They contain L-Cysteine, an amino acid found in most protein-rich foods.
It has a role in maintaining the immune system and also acts as an antioxidant to protect the liver, lungs, and brain.
The ability of L-cysteine is to promote the metabolism of fats and the production of muscle tissue.
The addition of vitamin B6 improves metabolism, and helps speed up the absorption and assimilation of L-cysteine in the body. This makes it one of the most effective ways to take L-Cysteine.
