Research overview
Glutathione is a tiny, naturally occurring molecule made of just 3 amino acids (protein building blocks) that your own cells make constantly — it's often called your body's "master antioxidant." It's not something invented in a lab from scratch; rather, medical and cosmetic versions are made to be identical to what your body already produces, then given as a pill, IV drip, or injection (Forman et al., Mol Aspects Med 2009).
Mechanism under study
Think of glutathione as your body's built-in cleanup crew. It grabs harmful, unstable molecules (called oxidants) floating around your cells and neutralizes them before they can cause damage, kind of like a sponge soaking up a spill before it stains the carpet. It also helps escort out toxins and certain drugs from your system, and it's a way your cells deliver the amino acid cysteine where it's needed (Forman et al.; Aebi et al.).
Human evidence summary
A well-run 6-month study gave 54 people either 250 mg or 1,000 mg of oral glutathione daily and found the higher dose raised glutathione levels in blood cells by roughly 30-35%, and in cheek cells by a striking 260%; it also boosted certain immune cells' ability to fight off threats (Richie et al., Eur J Nutr 2015). But confusingly, a separate study giving people a single 3-gram oral dose found no meaningful rise in blood glutathione levels at all (Witschi et al., Eur J Clin Pharmacol 1992) — suggesting that a single dose behaves very differently from taking it consistently over months. As for the popular skin-lightening use given through an IV, a careful review of the science found there simply are no published studies proving it works or is safe for that specific purpose (Davids et al.).
Preclinical evidence summary
The existing profile data doesn't report specific animal studies for glutathione — the available research described here is entirely from human studies.
