NOW Foods Glutathione 500mg delivers reduced glutathione, the body's primary intracellular antioxidant, at a clinically relevant dose to support cellular defense, oxidative balance, and liver function. Glutathione is found naturally in every cell and plays a central role in detoxification pathways. This product is well-suited for adults seeking antioxidant support or those with higher oxidative stress demands.
Why It's Worth Considering: NOW uses reduced glutathione (the active, electron-rich form) at 500mg per capsule, a dose commonly referenced in research, making it a straightforward and cost-accessible option in this category.

More category questions
Is oral glutathione effective or do I need IV?
Standard oral glutathione is largely destroyed by stomach acid. Three forms that DO work orally: liposomal glutathione (lipid-wrapped, bypasses digestion), S-acetyl glutathione (acetyl group protects the molecule), and Setria glutathione (patented reduced form with clinical absorption data). IV glutathione is the most direct route but requires clinic visits.
What does glutathione do for the skin?
Glutathione inhibits tyrosinase (the enzyme that produces melanin), resulting in skin brightening and more even tone. It also neutralizes free radicals that cause premature aging. Clinical studies show 500mg/day of oral glutathione produces measurable skin lightening within 4-8 weeks. This is one of the most popular uses in Asia.
How much glutathione should I take?
For general antioxidant support: 250-500mg liposomal or S-acetyl form daily. For skin brightening: 500-1000mg daily. For liver support: 500mg 2x daily. For detoxification protocols: 1000-2000mg daily (often combined with NAC and ALA). Take on an empty stomach for best absorption.
Can I just take NAC instead of glutathione?
NAC is more cost-effective for raising INTRACELLULAR glutathione levels. Direct glutathione supplementation is better for immediate systemic antioxidant support and skin benefits. The ideal approach is both: NAC (600mg 2x/day) for sustained intracellular production + liposomal glutathione (500mg) for direct systemic availability.
