Glutathione
otherAntioxidant (oral/IV wellness)
Research status · Dietary supplement
Available as an oral supplement; IV glutathione is offered in wellness/aesthetic settings and is not FDA-approved for skin lightening or anti-aging. Evidence for many marketed uses is limited.
Glutathione is the body's major intracellular antioxidant. Oral supplements exist; IV glutathione is marketed for skin and 'detox' but is not FDA-approved for those uses, and safety of unregulated IV products is a concern.
