NAC is an acetylated form of the non-essential amino acid L-cysteine.
N-Acetyl Cysteine (NAC) is an antioxidant, a sulfur-containing amino acid that the body needs to produce glutathione. Glutathione is an antioxidant enzyme produced in the body and has functions such as protection against free radical damage. Without glutathione, the body's immune system will be greatly reduced, making it difficult to defend against toxins and diseases.
