Formulation
Formula re: Contains
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 per-oxidase (one of the body's main antioxidant enzymes), which minimizes lipid peroxidation (fats turning rancid).
Formulation re: Does NOT Contain
Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.
