Seeking Health NAC Supplement provides N-acetyl-L-cysteine — the rate-limiting precursor for glutathione biosynthesis. NAC directly supplies cysteine to support the body's own glutathione production, as well as providing independent antioxidant, mucolytic and liver detoxification benefits.

Frequently Asked Questions

What is NAC and why is it important?

N-acetyl cysteine (NAC) is the rate-limiting building block for glutathione — the body's master antioxidant. NAC both supports glutathione production and has independent antioxidant effects, making it one of the most clinically studied supplements available.

How does NAC compare to taking glutathione directly?

NAC supports the body's own glutathione synthesis, while direct glutathione supplements provide it pre-formed. Both approaches are complementary. NAC has the additional benefit of independent mucolytic (mucus-thinning) effects and direct antioxidant activity.

What conditions have been studied with NAC?

NAC has extensive clinical research in respiratory conditions (COPD, bronchitis), liver protection, kidney protection, mental health support (OCD, addiction), neurodegenerative conditions, and as an antidote for paracetamol overdose.

How should I take Seeking Health NAC?

Take as directed by your healthcare professional. Typical supplemental doses range from 600-1800mg daily. NAC is best taken away from meals for optimal absorption and should be used with adequate hydration due to its mucolytic effects.
