NAC reduces TNF-alpha, an inflammatory molecule that causes insulin resistance, which helps the body's metabolism work better.

“There was a study that was published in sarcoidosis vasculitis and diffuse lung disease that showed that NAC suppressed TNF alpha by roughly 56% in immune cells. TNF alpha is a key inflammatory cytoine when you're talking about like obesity induced insulin resistance. There was a classic study that was in nature that showed that mice that were lacking TNF uh signaling were protected from insulin resistance and metabolic dysfunction. So if they knocked that out where that whole cytoine wasn't effective, it didn't have the same metabolic effect. So when NAC lowers this inflammatory cytoine, it's not just calming inflammation, it's restoring metabolic communication.”
