What it is

Glutathione is a small molecule made of three amino acids that your cells produce naturally. It’s one of the body’s main internal antioxidants.

Why it’s used in IV therapy

Usually given as a quick “push” at the end of a drip, marketed for detox, skin glow, and anti-aging.

What the evidence says

Your liver makes glutathione continuously and doesn’t need an infusion to “detox.” Small studies on IV glutathione for skin lightening show inconsistent results, and safety data at the doses and frequencies some clinics use is thin. Claims that it reverses aging, prevents cancer, or preserves memory are not supported by human evidence and are the kind of statements regulators scrutinize.

Side effects and cautions

Generally well tolerated in short-term studies. Because many glutathione products are compounded, sourcing matters — ask whether it comes from an FDA-registered outsourcing facility or licensed pharmacy.
