Glutathione FAQs

Why is glutathione called the master antioxidant?

Glutathione recycles other antioxidants (vitamin C, vitamin E), neutralizes free radicals, and supports liver detoxification. It's involved in nearly every cellular protection pathway. Levels decline with age, illness, and chronic stress.

Does oral glutathione actually raise body levels?

Liposomal and acetylated (S-acetyl) glutathione absorb better than standard reduced glutathione. Studies on liposomal forms show measurable increases in blood glutathione. NAC, the precursor, is another well-supported route.

How much glutathione should I take?

250–500 mg/day of liposomal or S-acetyl glutathione for general support. Take on an empty stomach for better absorption. Pair with vitamin C and selenium, which support glutathione recycling.
