Reduced L-Glutathione 150mg from Klaire Labs/SFI Health delivers glutathione in its biologically active, reduced form, the same form the body uses as a primary intracellular antioxidant. This formulation supports oxidative stress defense, liver function, and immune system integrity, and is particularly relevant for adults with elevated detoxification demands or compromised antioxidant status.
Why It's Worth Considering: Klaire Labs formulates to practitioner-grade standards with rigorous purity testing, and specifying the reduced (GSH) form matters, it bypasses the conversion step required by oxidized glutathione precursors, offering more direct cellular availability.

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.
