Research Context

How does NAC work?

Replenishes intracellular glutathione, the body's main antioxidant defence system. Reduces oxidative stress and inflammatory cytokines. In PCOS, may improve insulin sensitivity and reduce androgen levels. In endometriosis, may reduce pelvic inflammation and oxidative damage to tissues. Also modulates NF-κB inflammatory signalling.
