L-Cysteine is a crystalline free-form amino acid that is active in many body processes. L-Cysteine works in the liver to protect the body from harmful substances and may help to prevent oxidation of tissues. L-Cysteine, along with L-glutamic acid and glycine, is the rate-limiting precursor in the synthesis of glutathione peroxidase (one of the body's main antioxidant enzymes), which minimizes lipid peroxidation (fats turning rancid).

Supports sports performance and good health, while at the same time helping the liver detoxify

  • Helps the body rid itself of ammonia, a by-product of intense exercise
  • Helps the body recover after a workout

Suggested Use 1/4 teaspoon per day between meals. If you experience stomach irritation, take with meals.
