N-Acetyl Cysteine

Meaning

N-Acetyl Cysteine, commonly abbreviated as NAC, is a synthetic derivative of the naturally occurring amino acid L-cysteine and is clinically recognized as both a potent mucolytic agent and a critical precursor for the body’s primary antioxidant system. Its vital physiological role is the efficient replenishment of intracellular glutathione, the major endogenous antioxidant responsible for protecting cells against oxidative stress and facilitating crucial detoxification processes. Therapeutic applications range from respiratory conditions to supportive care for liver and metabolic health.
