Cysteine, L-Cysteine, NAC | Cysteine is a nonessential amino acid (protein building block), meaning that cysteine can be made in the human body. Cysteine is one of the few amino acids that contains sulfur. Cysteine is a component of the antioxidant, glutathione. Cysteine can also be converted into glucose and used as a source of energy. Cysteine strengthens the protective lining of the stomach and intestines, which may help prevent damage caused by aspirin and similar drugs. N-acetyl cysteine (NAC), which contains cysteine, is more commonly used as a supplement.
