5 interactions related to nac

acetaminophen + n-acetylcysteine

N-acetylcysteine (NAC) replenishes hepatic glutathione, which the liver uses to detoxify the toxic acetaminophen metabolite NAPQI. NAC is the standard antidote for acetaminophen overdose, and routine co-use at supplement doses is considered protective rather than harmful.

nac + vitamin c

NAC supplies cysteine for glutathione synthesis while vitamin C reduces oxidized glutathione (GSSG) back to its active form (GSH) and directly scavenges aqueous-phase free radicals. The two work together to maintain a high GSH:GSSG ratio inside cells.

nac + selenium

NAC supplies cysteine for glutathione synthesis while selenium is the obligate cofactor in glutathione peroxidase enzymes, which use glutathione to neutralize peroxides. Without adequate selenium, the glutathione that NAC helps produce cannot be fully utilized in peroxide detoxification.

nac + glutathione

NAC (N-acetylcysteine) provides the rate-limiting cysteine substrate the body uses to synthesize new glutathione intracellularly, while supplemental glutathione directly replenishes the circulating and extracellular pool. The two work through complementary upstream-and-downstream mechanisms to support antioxidant defense and phase II liver detoxification.

alcohol + nac

N-acetylcysteine (NAC) is a glutathione precursor that supports the liver's primary antioxidant defense against acetaldehyde — the toxic intermediate of alcohol metabolism. Animal studies and small human trials show NAC reduces alcohol-induced oxidative stress and may modestly reduce hangover symptoms, though it does not prevent liver damage from heavy drinking.
