Function: N-acetyl-cysteine is the acetylated form of L-cysteine which is more efficiently absorbed and used. It is also an antioxidant that is helpful against viruses. N-acetyl-cysteine has been used as a liver protectant and to break up pulmonary and bronchial mucus. N-acetyl-cysteine can boost glutathione levels in cells.
L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine from which L-cysteine can be produced in the body by a multi-step process. L-cysteine can act as an antioxidant, may prevent liver diseases, and can help to thicken the individual diameters of existing hair if taken regularly.
