Neuroendocrine Theory Of Aging, Part II:
Adaptive Homeostat Dysfunction
Ward Dean, M.D.

Part I of the Neuroendocrine Theory of Aging introduced Professor Vladimir Dilman’s revolutionary theory of the causes of aging, as well as potential therapeutic approaches.

The central thesis of the Neuro-endocrine Theory is that the aging process is caused by an age-related loss of central (hypothalamic) and peripheral receptor sensitivity to inhibition by hormones and other signaling substances.

This loss of hypothalamic sensitivity results in a progressive shifting of homeostasis—the body’s regulatory system for maintaining internal balance—and altered levels of hormones, neurotransmitters, and cell signalers. These metabolic shifts are believed to cause aging and the diseases of aging.

With this new understanding, novel therapeutic approaches to delay and even reverse aging become obvious. All of these areas will be discussed at greater length in forthcoming issues of Vitamin Research News.

Stress and Its Relation to Diseases and Aging
Professor Hans Selye defined stress as the nonspecific response of the body to any demand made upon it.(1) Stress-producing factors, or stressors, can be physical (work and exercise), biological (viral, bacterial and fungal), environmental (heat and cold), and situational (job, family, etc).

And while there are numerous stressors, the responses they elicit from the body are very similar. Reactions to stress are totally nonspecific, and common to all types of stressors. Emotional stimuli are probably the most common stressors that most of us encounter in our daily lives—but they elicit the same physiological response that an encounter with a saber-tooth tiger did for our cave-man ancestors.

While excess stress can adversely affect human health, certain types of stress are actually good for us and can benefit our health. For example, most people today recognize the multiple physical and emotional benefits to be gained from physical exercise.

Physicians once treated heart attacks with enforced inactivity. Now, we know that early resumption of physical activity (stress) is often the key to a successful recovery. According to Selye, stress is “the spice of life.” Certainly a life free of stress and devoid of challenges would be filled with boredom and hardly worth living. The most memorable events in life tend to be those that are the most stressful—situations that require us to rise to a challenge and push past our normal limits. Selye asks, “Who would enjoy a life of no runs, no hits, no errors?” When stress becomes excessive, is damaging or unpleasant, we then properly refer to it as “distress.”

Consequently, when we say someone is “under stress,” we usually mean excessive stress, or distress. Clearly, an issue for those looking to survive (and enjoy) the best in life is not how to avoid stress, but how to best manage stress.

How the Body Reacts to Stress
Neuroendocrine
1. General Adaptation Syndrome (GAS)
The General Adaptation Syndrome (GAS) was first described by Professor Selye in 1936 (Fig. 1). The GAS involves three progressive stages. The first stage is the alarm reaction, characterized by surprise and anxiety when confronted with a new situation. During the alarm reaction, the adrenal medulla produces epinephrine and norepinephrine—the “flight or fight” hormones. Additionally, the adrenal cortex is stimulated to produce additional cortisol and related hormones.

The second stage is that of resistance, where we learn to efficiently cope with the stressor (adaptation). An ideal situation is one in which adaptation occurs and continues until the stressful situation resolves, with a rapid return to the resting state. If the stage of resistance is prolonged, or the response is excessive, hyperadaptosis can occur.(2,3) While everyone’s adaptational capacity (i.e., tolerance to stress) is different— what may “charge one person’s batteries” may totally devastate someone else— ultimately our capacity for adaptation is limited.

Consequently, the third stage of the GAS is that of exhaustion, involving a depletion of our energy reserves and loss of adaptational ability, leading to fatigue, or other symptoms or diseases. Just as a chain breaks at its weakest link, exhaustion of our adaptive capacity results in stress-induced disease.

2. Neuroendocrine Adaptation Mechanisms—the Adaptive Homeostat
Dilman described the system that enables the body to deal with stress as the adaptive homeostat. The adaptive homeostat consists of the hypothalamus-pituitary-adrenal axis (Fig. 2). In order to fully appreciate the significance of Dilman’s work and his sometimes-unfamiliar terminology, a review of basic endocrinology may be helpful.
Neuroendocrine
Stressors normally excite the hypothalamus to produce corticotropin releasing hormone (CRH). CRH in turn causes the pituitary to produce adrenocorticotropic hormone (ACTH), which induces the adrenal cortex to secrete glucocorticoids (principally cortisol) and DHEA.

ACTH also stimulates the adrenal medulla to secrete the “flight or fight” hormones, epinephrine and norepinephrine. As cortisol levels rise they have an inhibitory effect on the hypothalamus and pituitary, which in turn decrease CRH and ACTH production, respectively. Conversely, when blood cortisol levels decrease, hypothalamic activity increases, releasing CRH.

This increases pituitary ACTH output, which stimulates the adrenal cortex to increase blood cortisol levels. In this cyclic manner, equilibrium is maintained in the system.

Cortisol concentrations in the blood undergo cyclic, diurnal (circadian) changes—higher in the morning, and lower in the afternoon and evening. These changes are due to variations in CRH and ACTH output, as well as to changes in hypothalamic and CNS sensitivity to cortisol (these changes in hypothalamic sensitivity are very important). With normal diurnal rhythm, blood ACTH levels rise between 3 and 6 a.m., causing increases in blood cortisol. These peak levels gradually decrease, dropping to minimal levels by night. Under normal conditions, basal morning cortisol concentrations are twice those at night.

Effects of Cortisol
Cortisol is an anti-inflammatory, catabolic hormone, which is essential to life. Release of high amounts of cortisol for short periods enables the body to deal with stress. Cortisol elevates blood glucose, decreases protein synthesis, and promotes fatty acid mobilization, making these substances available for energy and for synthesis of other compounds needed by different tissues of the body. Cortisol also helps to control allergies and inflammation by stabilizing lysosomes. Cortisol has been described by Dr. William Jefferies, author of Safe Uses of Cortisone, as “the hormone of life,” as without it we would be unable to adapt to the various stressors of life.(4) However, when cortisol is produced in excess over a prolonged period, it can have a number of adverse, damaging effects.
Neuroendocrine
Hyperadaptosis
Prolonged periods of exposure to elevated levels of cortisol (such as occurs during chronic stress) cause a number of adverse effects in the body. These include elevation of blood sugar (diabetes), sodium retention (resulting in hypertension), suppression of immunity, gastric ulcers, headaches, loss of bone density (osteoporosis), heart attacks, loss of even more hypothalamic glucocorticoid (cortisol) receptors (creating a “vicious cycle”), and increased neuronal cell death in the brain.(5)

Dilman theorized that with increased age the hypothalamus becomes less sensitive to the inhibitory effects of cortisol. Thus, increasingly higher levels of cortisol are required to inhibit cortisol production and restore balance. Dilman conclusively demonstrated the adverse effects of aging on the adaptive homeostat in women by measuring cortisol levels in surgical patients of various ages before and after surgery.(6)

His study revealed that while there were no differences in basal cortisol levels in women of different ages, in older women cortisol levels rose faster, went higher, and remained elevated longer following surgery. This confirmed that the stress response is more intense and of longer duration with increased age (Fig. 3). Indeed, after age 40 many people undergo a characteristic change of appearance with age, as faces become moon-like and fat accumulates around the waist.
Neuroendocrine
These changes are usually accompanied by a relative loss of fat and muscle on the arms and legs. When severe, these changes cause the person to resemble someone with Cushing’s Syndrome. Cushing’s Syndrome results from chronic excessive exposure to cortisol (Fig. 4).

In many ways, age-related metabolic and physiologic changes in the adaptive homeostat resemble the body’s response to chronic stress and prolonged exposure to excess cortisol. Dilman coined the term hyperadaptosis to describe this state. He believed that aging itself is a chronic stressor, and that everybody suffers, to a greater or lesser degree, from hyperadaptosis.

Diagnosis
Diagnosis of hyperadaptosis is usually based on a spectrum of signs and/or symptoms listed in Table 1. These signs and symptoms are similar to those found in persons who suffer from hypoglycemia, hypothyroidism, chronic fatigue, and fibromyalgia—all of which may be related to hyperadaptosis.

Often, treatment is initiated on an empirical basis (i.e., “educated guesswork”), with no further testing, since treatment is relatively benign and the likelihood of improvement so high.

There are a number of tests that may contribute to the diagnosis, including blood or salivary tests of a.m./p.m. cortisol levels, and the DHEA-S/cortisol ratio. The low-dose dexamethasone-suppression test (used by many psychiatrists to evaluate depression) is considered the “gold standard.” These tests provide objective information on which to base the optimal therapeutic program.
Neuroendocrine
Prevention and Treatment of Hyperadaptosis —Therapeutic Approaches / Intervention Based on the Neuroendocrine Theory

Dilman proposed that the most effective approaches to delay (and even reverse) the aging process and ameliorate the diseases of aging were to:


  1. Restore hypothalamic (and peripheral) receptor sensitivity;
  2. Restore hormone levels to more youthful values by hormone replacement therapy;
  3. Prevent damaging effects of the hormones(3);
  4. Restore intracellular bioenergetics.

1. Restore Receptor Sensitivity
With regard to the adaptive homeostat, hypothalamic resensitizers that seem to be most effective include combinations of adaptogenic herbs such as: Siberian ginseng (Eleutherococcus senticosus), Manchurian thorn tree extract, Hawthorn extract, Echinopanax elatum, Schisandra, Rhapon-ticum carthinoides, Adjuga turkistanica; Aralia mundshurica, Rhodiola rosea Myricetin, Magnolia officinalis, Phelloden-dron amurense, and Ashwagandha (Withania somnifera). These are all contained in VRP’s premier line of adaptogenic formulas—AdaptaPhase® I and II, and Cortisol Control.

Other substances that restore cortisol receptor sensitivity include phosphatidylserine (100 to 300 mg per day); the anti-diabetic drug, Metformin (Glucophage) (500 mg two to three times per day), and the anti-epileptic drug, Dilantin® (100 mg twice per day).

All of the above-mentioned substances have been documented to enhance the body’s response to cortisol—essentially restoring the adaptive homeostat to a more youthful state.

2. Hormone Replacement Therapy
The three hormones which drop most dramatically with age are: 1) DHEA(8) (Fig. 5), 2) melatonin(9) (Fig. 6), and 3) pregnenolone. These are all integrally related to the adaptive homeostat. I recommend that these three hormone/dietary supplements be considered by virtually everyone after age 35.

Neuroendocrine


Melatonin, produced by the pineal gland, has been called “the anti-stress hormone,” due in large part to its ability to regulate rhythms of other hormones, and to its ability to blunt the negative effects of cortisol.(10) Melatonin dosages generally range from 750 mcg to 6 mg per day, at bedtime.

DHEA, the most abundant steroid in the body after cholesterol, is produced by the adrenals. Dosages of DHEA found to be effective usually range from 12.5 to 50 mg per day (lower doses for women, higher doses for men). Pregnenolone is an anti-inflammatory neurosteroid that is also produced by the adrenal glands. Levels of pregnenolone are believed to decrease as profoundly as DHEA. Replacement dosages range from 10 to 100 mg per day.

In order to mimic the body’s own hormonal cycles (DHEA and pregnenolone levels are highest in the morning, and lowest in the late afternoon and evening), I recommend that these hormones be taken first thing in the morning. Restoration and maintenance of melatonin, DHEA and pregnenolone to youthful levels can play a tremendous role in enhancing quality of life and preventing age-related degenerative diseases.

Although chronically elevated levels of cortisol are generally harmful, and relative hypercortisolemia occurs with age, there are times when additional cortisol is beneficial and necessary, such as when 1) an additional stressor is experienced that exceeds the body’s ability to adapt; or 2) the adrenals are exhausted due to overwhelming acute or chronic stress.

Adrenal support may be accomplished by the use of 1) low-dose hydrocortisone treatment (as outlined in Dr. William Jefferies’ book, Safe Uses of Cortisone), or 2) intravenous adrenal cortical extract (available from many physicians who administer chelation therapy). Nutritional supplementation with adrenal glandular supplements and/or glycyrrhizin may also be used.

Glycyrrhizin is a nutritional supplement extracted from licorice. By mimicking the effects of cortisol, glycyrrhizin offers users a safe and natural method for supplementing the body’s endogenous cortisol production to “give the adrenals a rest.” In doses of 25 to 100 mg per day, glycyrrhizin has been demonstrated to be of benefit in a wide range of conditions, including colds and flu, asthma, allergies, chronic fatigue, hypoglycemia and other acute stressful conditions.

Glycyrrhizin, and its “cousin,” cortisol, however, are like two-edged swords. In small to moderate doses, usually for short periods, they can be very beneficial. In excess, they can cause a number of adverse side effects. Consequently, it is very important to use the minimum effective dosage of glycyrrhizin, and to use it intermittently as needed (usually, for no more than one to two weeks at a time).

Periods of glycyrrhizin use should be interrupted by two to three weeks of non-use. Many people find that taking 25 to 100 mg per day of glycyrrhizin provides significant relief of symptoms of chronic fatigue, fibromyalgia, and other conditions that are related to “adrenal exhaustion.”

In order to mimic the body’s normal rhythm of cortisol, I recommend that glycyrrhizin be taken first thing in the morning, approximately 30 minutes before breakfast, and another (usually smaller) dose (if needed) before lunch. With glycyrrhizin, as with many supplements—more is not necessarily better. Only the minimum dose that produces the desired effect should be taken.

Whenever cortisone or glycyrrhizin support is used, I recommend that it be combined with one or more of the adaptogenic substances mentioned above to maximize the effectiveness and minimize the dosage and side effects of the supporting substance.

Vitamin E:
Still Beneficial After All These Years
James South, M.A.

Vitamin E has been safely used by tens of millions of Americans over the past 55 years, and it is one of the most popular individual vitamin supplements. In light of the recent trumped-up adverse publicity regarding vitamin E, here is a brief but reassuring overview of the many benefits of vitamin E supplementation.

I will only focus on five major areas of vitamin E’s benefits, but this by no means exhausts the areas of health and disease where vitamin E is known to provide benefit. In addition, the studies cited in each section represent only a sampling of the many favorable reports on vitamin E available in the published scientific literature.

Vitamin E: What Is It?
“Vitamin E” (VE) is a term used to designate a family of eight closely related fat-soluble antioxidants: alpha-, beta-, gamma- and delta-tocopherols, and alpha-, beta-, gamma- and delta-tocotrienols.(1) Traditionally, alpha-tocopherol or mixed tocopherols have been the main VE supplement forms sold in the United States. Recently, gamma-tocopherol and mixed tocotrienol supplements have also become available. VE occurs in both a natural form (called d-alpha tocopherol or RRR-tocopherol) and a synthetic form (known as dL-tocopherol or all-racemic tocopherol). D-alpha tocopherol has generally been the most popular form, and there are sound biological reasons for alpha’s popularity.

In recent years a protein made by the liver—alpha-tocopherol transport protein —has been discovered that selects d-alpha tocopherol for transport throughout the body, while leaving most of the other tocopherols and stereoisomers of synthetic E to be degraded and excreted.(2)

Even though gamma-tocopherol is more plentiful than alpha-tocopherol in the American diet, because of the action of the alpha-tocopherol transport protein, plasma levels of gamma-tocopherol are only about 10 percent as high as plasma levels of alpha-tocopherol.(2)

Gamma-tocopherol has been shown to be a more effective protector against toxic peroxy-nitrites than alpha-tocopherol, yet it has been shown that alpha-tocopherol “alone is sufficient to remove any peroxynitrite-derived reactive nitrogen species in vivo [in the body].”(1) The need for gamma-tocopherol to detoxify peroxynitrite only occurs if all alpha-tocopherol body stores are exhausted.(1) In addition, alpha-tocopherol has been shown to have many non-antioxidant functions shared little or not at all by the other tocopherols.(2) Thus, alpha-tocopherol can rightly be considered the “star” of the vitamin E family.

Vitamin E: Neuroprotector
Human, animal and in vitro (test tube) research has shown multiple ways in which alpha-tocopherol protects the brain and nerves. A study reported in 1997 found that natural alpha-tocopherol slowed the progression of Alzheimer’s disease. In the study, 341 patients with moderate Alzheimer’s were given selegiline (a prescription drug), alpha-tocopherol, placebo or alpha-tocopherol plus selegiline for two years. The primary outcome was the time to occurrence of “death, institutionalization, loss of the ability to perform basic activities of daily living, or severe dementia.”(3)

Alpha-tocopherol delayed the primary outcome for 670 days, compared to 440 days for the placebo.3 A prospective study of 633 persons 65 or older followed their health state an average of 4.3 years. At that time 91 of the participants had developed Alzheimer’s. None of the 27 VE supplement users had developed Alzheimer’s, compared with a predicted 3.9 cases among that group.(4)

A study that followed 958,000 subjects and their death rates from amyotrophic lateral sclerosis (ALS) from 1989 to 1998 found that those who used VE supplements for 10 years or more had a 62 percent lower death rate from ALS than those who used no VE, while those who used VE for less than 10 years had a 41 percent lower death rate from ALS than non-VE users.(5)

Several studies have shown that 1,600 IU VE daily can significantly reduce the abnormal involuntary movements in patients suffering from tardive dyskinesia, a neurological disorder caused by use of neuroleptic (antipsychotic) prescription drugs.(6,7) Based on the known biochemical pathology of Alzheimer’s disease, Prasad and colleagues have devised a protocol using VE along with other antioxidants to prevent/treat Alzheimer’s disease.(8)

Poulin and coworkers fed “high-dose” VE to “middle-aged” and “old” mice, and compared them to a control group of mice. They found that the VE regimen reduced the “normal” oxidative neuronal damage that occurs with aging, and subsequent neuronal cell death.(9) Hassoun and associates fed the toxin TCD-dioxin to rats, with or without extra VE or ellagic acid. Dioxin alone caused significant production of superoxide radical, lipid peroxidation and DNA strand breaks in the cerebral cortex and hippocampus, while VE provided significant protection against these effects, more than provided by the antioxidant ellagic acid.(10)

Conte and colleagues gave extra VE to some 11-month-old mice, while control mice got no extra VE. The mice were subjected to repetitive concussive brain injury, a known risk factor for developing Alzheimer’s disease. The VE-fed mice showed significant decrease in brain lipid peroxidation levels compared to control mice. Lipid peroxidation is especially a problem for the brain, since the brain contains the highest level in the body of the peroxidation (rancidity)-prone fatty acid, DHA. The VE-fed mice also did not show the increase in amyloid-beta peptide formation (a known major biochemical risk factor for Alzheimer’s) found in the control mice, and the VE-fed mice had a significant reduction in learning deficits compared to the control mice.(11)

When mice were subjected to electroshock-induced seizures, a significant increase in brain lipid peroxides was found. Both clobazam (an anti-epileptic drug) and VE reduced brain lipid peroxide after electroshock. Administering combined VE and clobazam significantly reduced the intensity and duration of the seizures, with only minimal seizures occurring.(12) Abd el-Fattah and associates found that giving VE along with aluminum to mice significantly reduced the loss of brain glutathione and increase in brain lipid peroxidation that otherwise would have occurred.(13)

Vitamin E: Immune Booster
VE is the chief fat-soluble antioxidant in human tissues—it is the “lipid soluble, chain-breaking free radical scavenger” that protects cell membranes.(14) When VE sacrifices itself to protect polyunsaturated fats in cell membranes, it becomes the (weak) tocopheroxyl free radical. This free radical VE is then reduced back to VE by vitamin C.(14) Thus, vitamin C and VE act synergistically to protect membranes from lipid oxidation and play a key role in protecting phagocytes (immune cells) from damage by self-generated free radicals, since immune cells have a high percentage of easily oxidized fatty acids in their membranes.(14) Phagocyte membrane auto-oxidation is a major immune problem—so much so that neutrophils typically die from oxidant auto-oxidation after killing just three to 20 bacteria.

A study published in 1998 gave 30 women (average age 72) 200 mg VE and 1,000 mg vitamin C per day for 16 weeks. Ten were healthy controls, 10 suffered from heart disease (CHD) and 10 had major depressive disorder (MDD).(15) The study found a 60-to-70-percent drop in serum lipid peroxides in the CHD and MDD groups, and significant increases in neutrophil adherence, chemotaxis/migration and phagocytic (germ-killing) activity in all three groups.

The phagocytic index—how many germs a neutrophil can kill before dying itself—rose 260 percent in the controls, 225 percent in the MDD group, and 1,000 percent in the CHD group (Fig. 1). The vitamins also lowered superoxide production in all three groups—a good thing, as aging usually leads to a major increase in superoxide production in phagocytes. Excessive superoxide production by neutrophils shortens their lives.

VitE


The study also found a massive increase in lymphocyte proliferation (formation of new white blood cells) in response to mitogen testing in all three groups. There was also a modest drop in serum cortisol in all three groups, especially large in the CHD group—cortisol being an immunotoxic stress hormone that often increases with aging.(15)

In 1990 Meydani and coworkers gave 32 healthy older adults either placebo or 800 mg synthetic VE for 28 days.(16 )They found that in the VE group: 1) VE content of plasma, macrophages and lymphocytes was significantly increased; 2) there was significant increase in delayed-type hypersensitivity—a skin test that measures cell-mediated immunity; 3) interleukin-2 production and mitogen responses were increased; 4) PGE2 (an immunosuppressive prostaglandin) production and plasma lipid peroxides were reduced.

The decrease in PGE2 was especially important. Lymphocytes from elderly people are more sensitive to the immunosuppressive effects of PGE2. Macrophages from healthy elderly people tend to make more PGE2 then those from healthy young people, and PGE2 suppresses production of interleukin-2, the most critical cytokine (immune “hormone”) for promoting optimal T lymphocyte activity.(16)

Moriguchi and coworkers fed rats high doses of VE (100 to 2,500 mg VE per kg diet).(17) They found that the number of alveolar (lung) macrophages and splenic lymphocytes increased significantly after just 10 days. Splenic lymphocytes’ response to mitogens (inducers of immune activity) and natural killer cell activity increased with increasing VE dietary content. Rats fed the highest VE dose had a five-fold increase in the ability of their macrophages to ingest and destroy sheep red blood cells.(17)

Wang and associates fed female mice 15-, 150- and 450-fold increases in VE compared to normal dietary levels, after the animals had been infected with a retrovirus that causes murine (mouse) AIDS, which is functionally similar to human AIDS.

VE significantly restored spleen lymphocyte production of interleukin-2 and interferon-gamma, two key immune proteins. The infection also elevated levels of IL6 and IL10, two immunosuppressive inflammatory cytokines, and all three VE levels returned to normal. VE restored retrovirus-suppressed natural killer cell activity.

VE also alleviated the AIDS symptoms of enlarged spleen and excessive gamma globulin levels. The retrovirus infection induced some tissue nutritional deficiencies, while VE largely restored the levels of some nutrients (Vitamin A, VE, zinc and copper) in the liver, intestine, blood serum and thymus gland.(18,19)

Moriguchi and Muraga published a major review on VE and immunity in 2000. They concluded: “In vitamin E deficiency most of the immune parameters show a downward trend, which is associated with increased infectious diseases and the incidence of tumors. In contrast, vitamin E supplementation has various beneficial effects on the host immune system. The decreased cellular immunity with aging or during the development of AIDS is markedly improved by the intake of a high vitamin E diet. In addition, VE plays an important role in the differentiation of immature T cells in thymus. Vitamin E deficiency induces the decreased differentiation of immature T cells, which results in the early decrease in cellular immunity with aging…. Conversely, VE supplementation induces a higher differentiation of immature T cells…which results in the improvement of decreased cellular immunity in the aged. Furthermore, VE supplementation induces the early recovery of thymic atrophy following x-ray irradiation. Taken together, these results suggest that VE is an important nutrient for maintaining the immune system, especially in the aged.”(20)

Vitamin E: A Diabetic’s Best Friend?
Millions of Americans suffer from diagnosed diabetes, most commonly type 2 (non-insulin dependent). Millions more suffer from undiagnosed diabetes, and millions also have “pre-clinical” (i.e., borderline, developing) type 2 diabetes. People with diabetes are at increased risk of heart disease, as well as increased risk of vision, kidney and nerve damage. Both human and animal studies have shown VE may provide metabolic benefit to diabetics.

Paolisso and associates compared type 2 diabetics and control subjects before and after four months of 900 mg Vitamin E per day. In diabetic subjects VE significantly reduced glucose area under the curve (improved glucose tolerance), increased glucose disappearance from blood, total glucose disposal and nonoxidative glucose metabolism. The researchers concluded, “administration of pharmacologic doses of vitamin E is a useful tool to reduce oxidative stress and improve insulin action.”(21)

Upritchard and coworkers fed 57 type 2 diabetics tomato juice, VE (800 IU per day), vitamin C or placebo for four weeks.22 They found that VE decreased susceptibility of LDL cholesterol to oxidation by 54 percent. Oxidized LDL is generally believed to promote cardiovascular disease. C-reactive protein levels fell 49 percent with VE use. The authors concluded, “[C-reactive protein] is a sensitive marker of systemic inflammation, and chronically high levels predict increased risk of future coronary events.”(22)

Tutuncu and colleagues gave 21 type 2 diabetics either placebo or 900 mg synthetic VE for six months.(23) They found that VE improved some electrophysiologic parameters in peripheral nerves after six months (diabetics are prone to peripheral nerve pain and damage).

Bursell and associates compared 36 type 1 diabetics with less than 10 years disease duration and nine controls in an eight-month crossover trial with 1,800 IU VE per day.24 Baseline retinal blood flow was significantly decreased compared to control subjects, but was significantly normalized after VE treatment. VE also significantly normalized elevated baseline creatinine renal clearance in the diabetic patients. “This physiological normalization in the early stages of diabetes could ameliorate the risk for development of retinal or renal [kidney] complications.”(24)

Jain and colleagues gave 35 type 1 diabetics placebo or 100 IU synthetic VE per day for three months.(25) Glycosylated hemoglobin and triglycerides were significantly reduced by VE. Blood glucose was 24 percent less in the VE group compared to baseline. There were no changes in the placebo group.

VitE


Paolisso and coworkers gave 25 type 2 diabetics 900 mg VE per day or placebo in a three-month crossover study.(26) VE reduced plasma glucose 10 percent, triglycerides 26 percent, free fatty acids 38 percent, total cholesterol 18 percent, LDL 22 percent and glycosylated hemoglobin 9 percent. The researchers concluded: “Daily vitamin E supplements seem to produce a minimal but significant improvement in the metabolic control in type [2] diabetic patients.”(26)

Davi and associates compared 62 type 2 and 23 type 1 diabetics to age-matched controls.(27) They tested for urinary levels of F2-isoprostane, a bioactive product of arachidonic acid (fatty acid) peroxidation. F2-isoprostane levels were twice as high for both type 1 and type 2 diabetics compared to controls.

Urinary F2-isoprostane was linearly correlated with blood glucose and urinary dehydro-thromboxane B2 (TXM). TXM is a metabolite of thromboxane B2, a prostanoid that promotes cardiovascular disease. Taking 600 mg VE per day for 14 days lowered urinary F2-isoprostane 37 percent and TXM 43 percent in the type 2 diabetics. The reduction was significantly correlated with an improvement in metabolic control.

Qiam and coworkers treated streptozotocin-induced diabetic rats for five weeks with VE and vitamin C.(28) They found that vitamin C plus VE significantly decreased glycated hemoglobin, glycated LDL, advanced glycosylation endproducts (AGEs) in the kidney, and MDA (a lipid peroxidation byproduct) in blood serum and the kidney. They concluded that joint supplementation by VE and vitamin C could protect the diabetic kidney from the damage induced by chronic hyperglycemia.(28)

Vitamin E vs. Cancer
Several human and animal studies have suggested a role for alpha-tocopherol E in cancer prevention. In one human study, 29,133 Finnish male smokers aged 50-69 received 55 IU synthetic E, beta-carotene, both agents, or placebo, and were followed for five to eight years.(29) During the follow-up period, 246 new cases of prostate cancer and 62 deaths from the disease occurred.

Among those getting VE, there was a 32 percent lower incidence of prostate cancer, and a 41 percent lower death rate, compared to those not getting VE. Over 991,000 U.S. adults were monitored from 1982 to 1998 in the Cancer Prevention Study II.(30) During follow-up 1,289 bladder cancer deaths occurred. Regular VE supplement use for more than 10 years was associated with a 40 percent lower risk of bladder cancer mortality.

Twenty-five rats fed a VE-sufficient diet and 20 rats fed a VE-supplemented diet for 12 months were treated with the kidney-cancer-causing agent iron nitrilotriacetate for the first three months.(31) After 12 months, 11 of 25 E-sufficient rats (44 percent) developed kidney cancer, while just one of the 20 E-supplemented rats (5 percent) developed cancer.

Sixty male hamsters were divided into six groups.(32) They were all treated with DMBA (7,12-dimethylbenzanthracene) to induce oral cancer. The control group got no added antioxidants, while the other five groups got either beta-carotene, synthetic VE, vitamin C, glutathione, or a combination of all four, given orally by pipette. The combination gave the greatest reduction in tumor burden, while beta-carotene, VE and glutathione also individually significantly reduced tumor burden.

The most interesting results with regard to cancer and VE come from studies done with a specific form of VE: d-alpha tocopheryl succinate. This is the form of VE typically used in dry (non-oily) VE supplements. In vitro studies have shown d-alpha tocopheryl succinate to be effective in killing (by apoptosis) or reducing proliferation of various cancer cell types, including prostate, breast and gastric cancer.(33-42) Using injected d-alpha tocopheryl succinate, colon cancer, melanoma, breast cancer and liver metastases were inhibited in test animals, with 80 percent inhibition of transplanted tumor cells in many cases.(43-48)

The most exciting results, however, have occurred with d-alpha tocopheryl succinate in oral form. It had been assumed that when it was given orally, it would be hydrolyzed by intestinal enzymes into VE and succinic acid, yet in vitro and animal studies indicated that the intact d-alpha tocopheryl succinate molecule was necessary to work its “anticancer magic.”

Yet Prased and colleagues have reported that d-alpha tocopheryl succinate given orally to humans was found intact in blood plasma.(49) Several animal studies have also found that given orally, it could significantly reduce tumor burden (50) or colonic aberrant crypt foci.(51) Exon and associates also found that “[d-alpha tocopheryl succinate] accumulates in most tissues following dietary exposure.”(51)

Oral d-alpha tocopheryl succinate in combination with other micronutrients and radiation or surgery has also shown encouraging results.(49) Kumar and coworkers also found that it enhances radiation damage to cancer cells, but reduces radiation damage to normal cells.(52) On an anecdotal basis, I have observed several people who have incorporated 1,200 to 2,000 IU d-alpha tocopheryl succinate into a natural anti-cancer regimen with excellent results and no side effects.

Vitamin E: Good For The Heart
Vitamin E has traditionally been promoted as a heart-healthy supplement, yet the published studies reveal a somewhat mixed picture. Three large-scale prospective studies have shown significant apparent benefit from VE supplementation. In one study, 87,000 female nurses aged 34 to 59 who were initially free of diagnosed cardiovascular disease and cancer were followed from 1980 to 1988.(53)

During that period 437 nonfatal heart attacks and 115 deaths due to coronary disease occurred. After statistical adjustment for age, smoking status, risk factors for cardiovascular disease and use of other antioxidants, those who took at least 100 IU VE per day for two years or more had a 41 percent lower incidence of major coronary disease than those who didn’t.

In another study, 39,910 male health professionals 40 to 75 years old, who were initially free of diagnosed coronary heart disease, diabetes and hypercholesterolemia, were monitored from 1986 to 1990.(54) Men who took at least 100 IU VE per day for two or more years had a 37 percent lower risk of developing heart disease than those who didn’t. Among those who used VE and had never smoked, the heart disease risk was 48 percent lower compared to non-VE users.

In yet another study, 11,178 persons 67 to 105 years old were studied from 1984 to 1993.55 Use of VE reduced risk of all-cause mortality 34 percent, coronary heart disease mortality 47 percent, and cancer mortality 59 percent. Adjustment for alcohol use, smoking history, aspirin use and medical history did not significantly change the results.

The GISSI trial involved 11,324 Italians who had survived a heart attack.56 Although initial results seemed to show no benefit from taking 330 IU synthetic VE daily, subsequent analysis comparing only VE and placebo, leaving out other treatment groups, found a 20 percent reduction in cardiovascular deaths, a 25 percent reduction in coronary deaths, and a 35 percent reduction in sudden death.

In the CHAOS trial, 2,002 subjects with proven coronary atherosclerosis received VE (400 or 800 IU) or placebo.(1) After an average of 510 days, those getting VE had a 77 percent reduction in the risk of nonfatal heart attack.

In the SPACE trial, 196 hemodialysis patients with pre-existing cardiovascular disease were given 800 IU VE or placebo per day.(57) After an average of 519 days, five of 97 VE patients (5.1 percent) had suffered a heart attack, while 17 of 99 placebo patients (17.2 percent) had suffered a heart attack, producing a 70 percent risk reduction among VE-users.

However, three other trials, including two very large studies (with 9,500 and 20,536 people) failed to find any benefit from VE in cardiovascular disease.(58-60)

Vitamin E: Heart-Protective Mechanisms
Given the mixed picture from prospective and clinical trials, a skeptic might consider Vitamin E’s heart benefit doubtful, at best. And if these trials were our only source of knowledge concerning VE’s heart benefit, one might reasonably side with the skeptics. Yet a vast amount of scientific research into VE’s mechanisms have uncovered so many ways VE (primarily alpha-tocopherol) protects heart/arteries:

• VE has been shown to reduce LDL oxidation and macrophage uptake of oxidized LDL.(61-63)
• VE has been shown to reduce endothelial cell (artery lining) injury.(61-63)
• VE reduces adhesion molecule expression,(61-63) which in turn reduces immune/endothelial cell adhesion.(61-63)
• VE reduces inflammatory cytokines and chemokines.(61-63) VE decreases smooth muscle cell proliferation.(61-63) VE reduces platelet aggregation and thrombus formation. (61-63)
• VE increases endothelial nitric oxide production, promoting arterial dilation (opening).(61-63)
• VE increases prostacyclin (PGI2) production, which protects artery linings, relaxes blood vessels and opposes abnormal clot formation, while reducing clot-promoting, vasoconstrictive TXA2 production.(61-63)

All of the preceding are generally believed to be important issues in the development or prevention of heart disease. Many of these VE benefits occur through nonantioxidant mechanisms of alpha-tocopherol.(1) Thus, given the positive prospective and clinical trials on the one hand, and the multitude of known heart/artery-protective VE molecular mechanisms on the other hand, VE (especially alpha-tocopherol) may still be presumed to be the “heart protector.”

Vitamin E and Friends
VE works at least in part through its antioxidant activity (Fig. 2). When alpha-tocopherol quenches a free radical, it becomes a (weak) tocopheroxyl radical. Vitamin C or CoQ10 (coenzyme Q10) can restore the tocopheroxyl radical back to alpha-tocopherol, but then they become oxidized also. Glutathione can restore vitamin C, but then it is oxidized. The “linchpin” of the antioxidant network, which can restore all the others, is lipoic acid.(64) While R-lipoic acid may be the superior form of lipoic acid, alpha-lipoic acid is still effective as well.(64)

Therefore, the ideal way to take VE is to combine it with either vitamin C or CoQ10, and either alpha-lipoic or R-lipoic acid. Several studies have shown VE plus CoQ10 to be more effective than VE alone.(65,66) Packer and associates’ classic article on lipoic acid as the direct or indirect recycler of oxidized VE, vitamin C, CoQ10 and glutathione indicates the importance of lipoic acid for optimal maintenance of the antioxidant network.(64) For those who can afford it, the truly optimum way to take VE is with vitamin C, CoQ10 and lipoic acid.

Why Test Hormones?

Jay H. Mead, M.D., and Erin Lommen, N.D.

Why do I need hormone testing? One size does not fit all when it comes to hormones. For decades Western medicine has prescribed Hormone Replacement Therapy (HRT) as if everyone needed the same thing and the same amount. Nothing could be further from the truth. Your hormones are like your fingerprints and in order to achieve optimal health, you need to know what your specific imbalances are. To find out about your hormonal status you’ll need to have lab tests performed. But what kind? There are several ways to test (saliva, serum and urine), but the state-of-the-art testing is through saliva. This is because it measures only the active portions of your hormones and it is these portions that determine how you feel. So if you’re seeking bio-identical hormone replacement (BHRT), you’ll need to know active hormone levels. In addition, if using a topical (transdermal) hormone preparation for treatment, saliva testing is the most accurate tool to measure and monitor your hormone status. Which Hormones Need Testing? The Five Major Players The major players in the sex hormone arena are estradiol, progesterone and testosterone. The main adrenal hormones are DHEA and cortisol. These five hormones will provide crucial information about your deficiencies, excesses and daily patterns, which then results in a treatment approach specifically tailored for you and one far more beneficial than the old “shotgun” approach. Below is a brief description of each of these five hormones to refresh your memory about what each one does and how they interact. Estrogen There are three forms of estrogen made by the body: estrone, estradiol and estriol. The form used in past hormone replacement therapies has been estradiol, often in the form of concentrated pregnant mare’s urine (Premarin®). It is a proliferative hormone that grows the lining of the uterus. It is also a known cancer-causing hormone: breast and endometrial (uterine) in women and prostate gland in men. However, it will treat menopausal symptoms such as hot flashes, insomnia and memory-loss. With the bio-identical formulas, estriol is matched with estradiol (bi-est) to provide protective effects and additional estrogenic benefits. The other major protector in keeping estradiol from running amok is progesterone. Progesterone Progesterone is called the anti-estrogen because it balances estradiol’s proliferative effects. It is considered preventive for breast and prostate cancers as well as osteoporosis. In addition, too little progesterone promotes depression, irritability, increased inflammation, irregular menses, breast tenderness, urinary frequency and prostate gland enlargement (BPH). Testosterone Testosterone is an anabolic hormone (it builds tissue) essential for men and women. Testosterone is necessary for bone health, muscle strength, stamina, sex drive and performance, heart function and mental focus. DHEA DHEA is an important adrenal hormone, which is essential for energy production and blood sugar balance. DHEA is a precursor to other hormones, mainly testosterone (in women). Cortisol Cortisol is your waking day hormone (highest in the morning and lowest at night). It is necessary for energy production, blood sugar metabolism, anti-inflammatory effects and stress response. Common Imbalances Some of the common imbalances identified through testing include estrogen dominance, estrogen deficiency, progesterone deficiency, androgen (testosterone) and DHEA excess or deficiencies, adrenal dysfunction (hyperadaptosis and adrenal fatigue). State-of-the-Art Saliva Testing Vitamin Research Products is pleased to announce the transition to a new form of saliva testing. This testing is accurate, easy to collect and FDA-approved, and it offers rapid results (turn-around-time) and requires a much smaller sample size (one fifth the volume previously required). Sample collection takes only two to three minutes. Four samples are collected and pooled to give a more accurate reflection of hormone levels (hormones fluctuate dramatically throughout the day, thus one sample does not reflect your average levels). The exception is cortisol, which has its own daily rhythm, and is measured before the samples are pooled. This state-of-the-art saliva testing is an easy and helpful way to determine your levels as you aim to achieve optimum hormone balance.

Veterinary Myth: Pets in Pain

Randy Aronson, VMD

I have heard a number of what I call “veterinary myths” in my exam rooms and on my radio talk shows. While some are harmless, I want to do my best to dispel those that run contrary to pets’ well-being. For example, I often hear, “My dog/cat is very slow to rise from lying down and will limp intermittently throughout the day. I don’t think he is in pain—he’ll chase toys or run after birds or rabbits.” I respond to this by informing my clients that most pets will not cry out or whine in pain. The aforementioned signs are the clinically significant signals that your pet is hurting. When your pet becomes excited, a release of epinephrine or adrenaline can completely override discomfort and he can appear pain-free. I have had animals walk into our veterinary hospital on broken limbs, just because they were excited! Here are some warning signs that pets are in pain: 1. Slowness in getting up after resting 2. Exercise intolerance or not being able to walk or play like they used to 3. Limping 4. Discomfort when you touch their back, neck or limbs (flinching, head turning or ear twitching). Addressing Joint Pain Here are some things to consider in helping your dog or cat with chronic joint inflammation or osteoarthritis: 1. Eliminate obesity and effectively manage the animal’s weight. There is a huge correlation between being overweight and joint disease. Discuss some grain-reduced, whole-protein diet alternatives with your veterinarian. 2. Introduce an exercise program. Again, under your veterinarian’s supervision, discuss play-time, walking or swimming exercises. We even teach dogs and cats to walk on a treadmill. There are veterinary conditioning or rehabilitation hospitals just for these types of programs. 3. Institute nutraceutical or vitamin supplementation to your pet’s existing diet. I always add a joint-supportive product to my feeding regimen (like VRP’s Nutri-Joint for Pets). 4. In addition, decrease the inflammatory response in affected joints and increase the fluid cushioning. To do so, supplement the diet with the anti-inflammatory proteolytic enzyme combination UniZyme™ and fatty acids such as those in VRP’s Natural Whole Food Concentrate for Dogs (it’s good for cats, too). Also, add EthylEPA™ (pinprick a gelcap and squeeze it into the food) or Neptune Krill Oil. I also recommend a daily anti-aging nutrition supplement—RejuvaPet, for example. 5. Do your best to provide an orthopedically sound place for pets to sleep. There are many beds and cushions available—even some with magnets that will help their aching joints. Avoid having your pets rest on cold floors or areas outside the home. 6. Consider some alternative modes of therapy such as acupuncture, chiropractic and homeopathy. In my experience, these therapies have been very helpful in alleviating pain. I always recommend to my clients to watch their pets closely to assess the treatments or nutritional support we have chosen. Observation is the best way to determine what’s working to help your pet enjoy the best health possible. Dr. Aronson is Director of VRP’s Veterinary Division. By blending Eastern and Western philosophies, he has helped animals and animal-lovers for more than 20 years in his veterinary practice, as well as through his radio call-in show and published columns.

Vitamin Wars Update

James South, M.A.

As reported in previous articles, the hourglass is rapidly emptying as our vitamin freedoms are seemingly slipping away before our eyes. Below are a few more late-breaking examples. Germany: Bad Science On January 20, 2005, the recently established German Federal Institute for Risk Assessment released a 341-page report attacking the safety of commonly available nutritional supplements, claiming that a “safe” level of vitamin C is only 225 mg; a safe level of vitamin B6 (pyridoxine) is only 5.4 mg; and a safe level of vitamin B12 (cobalamin) is only 9 mcg! This ridiculous report, full of pseudo-science, will add further fuel to the WHO/FAO/Codex attempt to set “safe upper potency limits” for supplements at levels only slightly above the current U.S. FDA RDAs (recommended daily allowance). NNFA: Siding with “Big Pharma” In the December 2004 issue of NNFA Today, the legal firm that represents National Nutritional Foods Association (NNFA), wrote a question-and-answer article dismissing any concerns about Codex, the EU Food Supplements Directive, etc. The NNFA is the trade group that allegedly represents the interests of the U.S. health food and vitamin industry and health food stores. Unfortunately, the NNFA has become dominated by the pharmaceutical industry, and continues to push the “big Pharma” line that Codex will have no effect on the American vitamin industry. That’s why it is imperative for vitamin consumers to educate their local health food store personnel on the Codex issue. Many Vitamin Research News readers have contacted me and told me the vitamin buyers/experts at their local health food stores had no awareness at all about the Codex issue when they were asked about it. Europe: More of the Same On January 25, 2005, the Alliance for Natural Health (ANH) presented its case against the EU Food Supplements Directive to the European Court of Justice. ANH director Rob Verkerk observed that the government supporters of the anti-supplement EU regulations did little to counter the legal and scientific challenge ANH presented to the Court. The Court is expected to release its ruling on the matter in June 2005, just shortly before the EU anti-supplement regulations are set to go into effect in August 2005. ANH still needs help with its legal bills in mounting this defense of supplement freedom. You can help online at www.alliance-natural-health.org. If the EU Food Supplements Directive is not overturned, the USA will be the last bastion of vitamin freedom left in the world. How much longer do you think it will last here? Remember: under its GATT, NAFTA, WTO and, probably soon, FTAA (Free Trade Area of the American) treaty agreements, the United States is required to continuously work to “harmonize” its regulations with the rest of the world.

Resveratrol Inhibits Development of Mammary Tumors in Mice
Breaking News 2/14/05
VRP Staff

Researchers report in the International Journal of Cancer that resveratrol, a component of red wine, inhibited the development of mammary tumors in mice and reduced the mean number and size of tumors in the animals. Past studies have indicated that resveratrol may possess anti-cancer activity on the basis of its in vitro effects on tumor cells and its effects in vivo on rodents transplanted with tumors or treated with carcinogens. Consequently, in the current study, the Italian researchers investigated resveratrol’s effects on the development of mammary tumors appearing in an experimental model of mice and breast cancer. Resveratrol supplementation delayed the development of spontaneous mammary tumors, reduced the mean number and size of mammary tumors and diminished the number of lung metastases in the mice. The researchers noted that resveratrol’s mechanism of action may be a result of its ability to downregulate the expression of a gene associated with breast cancer. Resveratrol also increased apoptosis in the cancer cells. Reference: Provinciali M, Re F, Donnini A, Orlando F, Bartozzi B, Di Stasio G, Smorlesi A.

Silymarin May Support Skin Health, New Review Indicates
Breaking News 1/31/05
VRP Staff

In a review of the medical literature published in the January 2005 issue of the International Journal of Oncology, researchers concluded that Silymarin, a plant flavonoid isolated from the seeds of milk thistle, shows promise in protecting the skin against damage from ultraviolet radiation. Several environmental and genetic factors are involved in skin cancer induction, the reviewers noted. However, exposure to chemical carcinogens and solar ultraviolet (UV) radiation are primarily responsible for several skin diseases including skin cancer. Chronic exposure of solar UV radiation to the skin leads to basal cell and squamous cell carcinoma, and melanoma. “Chemoprevention of skin cancer by consumption of naturally occurring botanicals appears a practical approach and therefore world-wide interest is considerably increasing to use these botanicals,” the researchers wrote. “Sunscreens are useful but their protection is not ideal because of inadequate use, incomplete spectral protection and toxicity.” Consequently, the reviewers looked at past published studies on Silymarin. They observed that Silymarin, in animal studies, has been shown to protect against skin cancer in animals exposed to chemical carcinogens as well as against skin cancer caused by UV radiation. In a number of studies, topical treatment resulted in inhibition of skin cancer in mice treated with chemical tumor promoters or exposed to UVB radiation. In addition, evidence gathered from at least one animal study suggests that Silymarin consumed orally may also afford protection against skin cancer. The reviewers note that a wide range of in vivo studies indicate that Silymarin possesses antioxidant, anti-inflammatory and immune-modulating properties that may lead to the prevention of skin cancer during in vivo animal models. “The available experimental information suggests that Silymarin is a promising chemopreventive and pharmacologically safe agent, which can be exploited or tested against skin cancer in the human system,” the researchers concluded. “Moreover, Silymarin may favorably supplement sunscreen protection and provide additional anti-photocarcinogenic protection.” Reference: Katiyar SK. Silymarin and skin cancer prevention: anti-inflammatory, antioxidant and immunomodulatory effects (Review). Int J Oncol. 2005 Jan;26(1):169-76.

CarnoSee Benefit after Six Months?

Question:

Dear Dr. Dean, I didn't get to start CarnoSee eyedrops until I was 58 1/2 years old. Is there any evidence that using it past 6 months will continue to improve a cataract? I'm 4 1/2 months into the program, but my right eye needs more help than I think another 1 1/2 months will give it.— Mr. K.



Response:

Dear Mr. K., There is no limit to the length of time you can use CarnoSee™. Most clinical studies of carnosine and N-acetyl carnosine lasted no more than six months. That seemed to be the time required for clinical improvement to be clearly demonstrated. However, I don’t know of any reason that it would not be of continued benefit beyond six months; in fact, I believe that it would be. Many people continue to use CarnoSee after their vision has improved, to maintain the benefit and prevent recurrence of their cataracts. Ward Dean, M.D.

Alternatives to Adderal for ADHD

Question:

Dear Dr. Dean, My 23-year-old son has been taking Adderall®XR for a few years now for ADHD (Attention Deficit and Hyper-activity Disorder). I have concerns with him being on this medication and the band-aid effect. I think it helps him focus and get things done, but he also is zombie-like and gets agitated easily. He would be interested in a natural approach that would also benefit his health. Can you help? — Ms. B.



Response:

Dear Ms. B., There are several approaches that may help. First, I suggest VRP’s DMAE 100 Plus. Have your son work up to a maximum of five capsules per day. Excessive DMAE is harmless, but may cause a headache or jaw tightness, due to excessive formation of acetylcholine. Another approach that may help him to reduce his Adderall is to take 500 to 1,000 mg of L-Tyrosine (Tyrosine Caps) or L-Phenylalanine in the morning, on an empty stomach. These amino acids act as neurotransmitter precursors for the same neurotransmitter system that is augmented by Adderall. A third approach is to try Lithium Orotate, in a dose of one or two capsules twice per day. Please note that these suggestions are not mutually exclusive, and that he can try these together, or separately, although I suggest that he start with one product at a time, for a week or so, to see if he can identify which ones help the most.

Hepatitis C and Cirrhosis

Question:

Dear Dr. Dean, I have had hepatitis C for 30 years, and now have cirhossis as a result of this virus. Please recommend products to purchase for my condition. Thank you. — Ms. M.



Response:

Dear Ms. M., First, I recommend VRP’s HepatoGen™ —a combination of nutrients designed to optimize liver function. Mild silver protein (VRP’s Silver Liquid)—oral and intravenously—has also been shown in some patients to help reduce the viral load. I also recommend anti-fibrotic/anti-cross-linking agents like Oral ChelatoRx, as well as AGEBlock, Benfotiamine AGE Inhibitor, and 1 to 2 grams of Carnosine each day. I hope these suggestions help. Ward Dean, M.D.

Alternatives to Andro

Question:

Dear Dr. Dean, Can you shed some light on the disappearance of andro (androstenedione and androstenediol) products? For those of us who have become accustomed to their use, is there a comparable/viable alternative? Also, can we expect an andro re-appearance to the marketplace? Your response may well determine how I approach my personal physician, who suggested andro in lieu of testosterone therapy. — Mr. G.



Response:

Dear Mr. G., I do not see the likelihood of andro returning to the marketplace as long as the current “anti-anabolic steroid” hysteria prevails (the Food and Drug Administration has banned andro products). We are working on a natural alternative that appears to elevate testosterone levels to a significant degree. In the meantime, however, you might revisit the issue of testosterone replacement therapy with your physician—either as injectable testosterone cypionate, 200 mg every 3 to 4 weeks (a very safe, conservative regimen), topical cream or gel, or natural testosterone troches, available from most compounding pharmacies. To control excess estrogen produced by higher testosterone levels, I recommend I3C (Indole-3-Carbinol) or BioDIM®, to help metabolize the estrogen, plus Resveratrol, a natural aromatase inhibitor, which will help prevent the conversion of testosterone to estrogen. If cost is no concern, I suggest Arimidex (a powerful prescription aromatase inhibitor) at a dose of about 1 mg twice per week. Ward Dean, M.D.

Statin Required to Reduce LDL?

Question:

Dear Dr. Dean, My good cholesterol (HDL) is high, but my bad cholesterol (LDL) is higher than my doctor wants. Despite the fact that my HDL/LDL ratio is low-risk, my doctor wants to put me on statins. I take a regimen of vitamins: Extension B-Plex (B-complex), Vitamin C (1,000 IU), Vitamin E (400 IU), CoQ10 (250 mg), Calcium/Magnesium, Green Tea Extract, Alpha-Lipoic Acid and Extend One multimineral. It doesn’t seem to matter to my doctor that my good cholesterol is high. Any suggestions? — Ms. I.



Response:

Dear Ms. I., Your physician is merely abiding by the latest mantra to use statins to bring your LDL to some very low level, which depends to a great degree on what article he has read most recently. I agree with you that the complete lipid picture is more important than isolated numbers. If you decide to keep your doctor happy and lower your LDL, before going on a statin, I would exhaust other potential lipid-lowering strategies. If you haven’t used high-dose Niacin, I recommend trying that first. Inositol Hexanicotinate (IHN, a form of Vitamin B3) is a non-flushing form of Niacin, usually effective in doses ranging from about 1,500 to 3,000 mg per day. See my articles on the lipid-lowering effects of Niacin on VRP’s website (www.vrp.com). Ward Dean, M.D.

Venous Insufficiency and Stasis Dermatitis

Question:

Dear Dr. Dean, Regarding the reddish/brownish discoloration of stasis dermatitis, how does one minimize or eliminate and get skin tone back? — Mr. E.



Response:

Dear Mr. E., “Stasis dermatitis” is caused by venous insufficiency. This may be due to “incompetent” valves in the veins of the lower legs, or poor muscle tone in the veins, causing poor blood return from the lower legs. There are several things you can do. The first is to simply give your legs a little assist from gravity several times daily, by lying down on the floor, with your feet elevated on a chair or against the wall. This, of course, causes a rapid return of blood from the lower extremities. Another effective approach is to use VRP’s Vein Support Formula. The ingredients in Vein Support Formula cause an increase in the tone of the veins, resulting in less “pooling” of blood, and enhanced venous return. Additionally, Bioflavonoid Complex with Quercetin may help reduce capillary fragility, which may also enhance venous integrity. Ward Dean, M.D.

Nutritional Aids to Orthopedic Surgery Recovery

Question:

Dear Dr. Dean, My 48-year-old husband will soon be undergoing laparoscopic repair of the L. supraspinatous tendon. Would Myosin™ and UniZyme™ be recommended for use during the post-surgical period? In addition to using OKG (ornithine alpha-ketoglutaric acid), are there any other substances you would recommend to facilitate healing? — Ms. H.



Response:

Dear Ms. H., Using Myosin and UniZyme™ should help relieve inflammation and speed healing. Also, in addition to OKG, you might consider additional Vitamin C, L-Lysine and L-Proline (several grams of each every day) to help the formation of connective tissue. Ward Dean, M.D.

Brittle, splitting fingernails

Question:

Dear Dr. Dean, My nails were always so strong. However, for the past year, all but my thumbnails have gotten very weak and soft. They are splitting and peeling. I now wear nail polish to protect the ends, otherwise they will chip and and peel even more. I have tried the Healthy Hair Caps, but that did not seem to help much. I think it is strange that my thumbnails continue to thrive and be strong. Do you have any suggestions as to what to take to strengthen them? Would taking an amino acid help? Thank you so much. — Ms. S.



Response:

Dear Ms. S., I agree that it seems strange that it is only your fingers, and not your thumbs. Do your fingers regularly contact some chemical that your thumbs do not? Fingernails are very similar to joints—i.e., they’re made of cartilage. Nutri-Joint is comprised of substances known to enhance cartilage formation. Gelatin, a time-honored dietary supplement, for nail health may also help. Let me know how you do. Ward Dean, M.D.
