Frequently Asked Questions

  • NAC is the precursor to glutathione, the body's master antioxidant. It's used for liver detoxification, respiratory health (thins mucus), mental health (OCD, addiction, depression), immune support, and protecting against oxidative damage from toxins, alcohol, and environmental chemicals. It's also the standard ER treatment for acetaminophen overdose.

  • For general antioxidant support: 600mg 1-2x daily. For liver support: 1200-1800mg/day. For respiratory health: 600mg 2-3x daily. For mental health (OCD, addiction): 1200-2400mg/day (clinical study doses). Take on an empty stomach for best absorption.

  • No, NAC is a precursor that your body converts INTO glutathione. NAC has better oral bioavailability than direct glutathione supplements (which are largely destroyed in the stomach). NAC is generally more cost-effective for raising intracellular glutathione levels than oral glutathione, though liposomal glutathione is a viable alternative.

  • Yes. NAC is well-tolerated for long-term daily use at standard doses (600-1800mg). It's water-soluble and excess is excreted. Common side effects are mild GI upset, which resolves by taking with food. There's no evidence of tolerance or need for cycling.

  • NAC supports alcohol metabolism by boosting glutathione, which is depleted during alcohol detoxification. However, timing matters: take NAC BEFORE drinking (at least 30 minutes prior), not after. Taking NAC after alcohol may actually increase liver toxicity by interfering with the detoxification sequence.
