N-acetyl cysteine

N-Acetyl-Cysteine (NAC) is a metabolite of the amino acid, cysteine. NAC is produced by the human body. It is rapidly metabolized into cellular glutathione, which provides immune support. In addition, NAC is a powerful antioxidant and a great detox agent. NAC also is a strong chelator, removing unwanted metal and toxins from the body. It has been used to provide respiratory support, cholesterol balance and heart health—the latter by reducing homocysteine levels.

Common Benefits

  • Helps immune support and cellular health.
  • Recommended as a antioxidant and detox agent.
  • Supports respiratory health.
  • May aid cholesterol balance and heart health.
  • It blocks AGEs (Advanced Glycation End-Products), which can accelerate age-related health problems.
