Research summary

Clinical research on NAC in healthy humans shows mixed but promising results. Studies demonstrate that NAC can reduce inflammatory markers including C-reactive protein and interleukin-6, lower homocysteine levels in a dose-dependent manner, and improve markers of oxidative stress. Evidence supports benefits for respiratory function, with some studies showing maintained lung function over 24 weeks compared to placebo deterioration. However, research also reveals important cautions: animal studies found that NAC supplementation in aged mice increased adenocarcinoma development in lung tissue, raising concerns about long-term safety in certain contexts. Most human clinical trials remain limited in scope, and long-term safety data in healthy populations is incomplete. Researchers recommend avoiding self-medication with NAC supplements pending results from ongoing clinical trials.
