Clinical Description
N-Acetylcysteine (NAC) is a powerful antioxidant and precursor to glutathione, the body’s master antioxidant. Each capsule provides 500mg of pharmaceutical-grade NAC. NAC replenishes glutathione levels, supporting liver detoxification, cellular protection, and immune function. It’s clinically proven to support respiratory health by thinning mucus and is used in hospitals for acetaminophen overdose. NAC also supports mental health, reduces oxidative stress, and may improve insulin sensitivity.

What are the side effects?
NAC is generally well-tolerated. Some people may experience mild nausea, especially on an empty stomach. Taking with food usually resolves this. NAC has a characteristic sulfur smell, which is normal.
When will I see results?
For respiratory health (mucus thinning), effects may be noticed within 1-3 days. For liver support and antioxidant benefits, allow 2-4 weeks. For mental health benefits, 4-8 weeks of consistent use may be needed.
Is this safe for long-term use?
Yes, NAC is safe for long-term use. Clinical studies show safety with continuous use for months to years. It's commonly used long-term for liver support, respiratory health, and antioxidant protection.
Can I take this with other supplements?
Yes, NAC combines well with most supplements. It's particularly synergistic with vitamin C, selenium, and milk thistle for liver support. Avoid taking with nitroglycerin without medical supervision.
