Quick Summary
A tripeptide antioxidant made in the body, sold as an oral supplement and, separately, as a compounded injectable. Available from 48 vendors, priced from $19.00 to $323.84.
Research: Richie et al, Eur J Nutr 2015 (PMID 24791752) was a randomised, double-blind, placebo-controlled trial over 6 months. At 1,000 mg/day, glutathione rose 30 to 35% in erythrocytes, plasma and lymphocytes and 260% in buccal cells; at 250 mg/day the rises were 17% and 29%. That trial tested ORAL glutathione and says nothing about injected or compounded forms.
Side effects: The oral trial above is the only controlled source verified for this page and it published no rate table. For compounded intravenous glutathione the FDA has published two compounding risk alerts. The alert of 27 August 2026 reports at least 30 patients who experienced fever, chills, pain, dizziness, signs of shock and sepsis-like symptoms after intravenous glutathione, some of them hospitalised. The alert of 7 June 2019 reports seven patients who developed nausea, vomiting, lightheadedness, chills, body aches and sneezing within minutes of an infusion, one of whom had low blood pressure and difficulty breathing and was transferred to hospital, and a further patient admitted for a possible bloodstream infection. The FDA attributes both episodes to excessive bacterial endotoxin in dietary supplement grade glutathione powder used to compound injectables
Dietary supplementSold as an oral supplement. Compounded injectable glutathione is a different product with no controlled trial behind it. FDA's compounding risk alert of 7 June 2019 followed a 1 February 2019 warning not to use L-glutathione powder distributed by Letco Medical of Decatur, Alabama, to compound sterile injectables; FDA laboratory testing of that powder found bacterial endotoxin at up to five times the limit FDA calculated for the doses the patients received. FDA's alert of 27 August 2026 concerns glutathione supplied by Medisca Inc of Plattsburgh, New York, with two Texas pharmacies recalling injectable products over elevated endotoxin. FDA states that dietary supplement grade ingredients should not be used to make injectable drugs.
