One trial of glutathione injections found liver changes and a collapse
In the one placebo-controlled trial of these injections, eight of sixteen had disturbed liver tests, one went into anaphylaxis, and the lightening never reached significance.
What the study found
Eight of sixteen on injected glutathione had disturbed liver tests
That came from the one placebo-controlled trial of these injections for skin lightening. One person in it went into anaphylaxis, a whole-body allergic collapse, and the lightening never reached significance. Two US pharmacies recalled contaminated batches two weeks apart in August 2026.
The caveat · Thirty-two finished the trial
Thirty-two people finished that trial, and the gap between glutathione and placebo ran close to the significance line, so the honest reading is no proven benefit rather than proven uselessness. The August recall reports came from the pharmacies themselves rather than independent checking, and neither notice names a death or a hospital admission.
