Glutathione: Antioxidant Support Under Physician Supervision

The Pep Club Medical Team3 min readUpdated May 12, 2026

What is glutathione?

Glutathione is a small tripeptide (gamma-glutamyl-cysteinyl-glycine) produced inside every cell of the body. It supports the cell's ability to neutralize reactive oxygen species, conjugate metabolic byproducts in the liver, and recycle other antioxidants such as vitamin C and vitamin E. Levels can vary with diet, alcohol use, environmental exposures, age, and chronic stress.

The glutathione preparations available through The Pep Club are compounded by a licensed compounding pharmacy and prescribed under U.S.-licensed physician supervision. Patients receive a personalized dose determined by their physician after a clinical intake.

Who can be considered

Patients evaluated for compounded glutathione typically describe fatigue, environmental-toxin exposure history, alcohol use, or post-illness recovery contexts. Eligibility is determined at consultation. Pregnancy, breastfeeding, known sulfur-compound allergies, and active asthma (for IV administration) are contraindications. The physician reviews all prior medications, including chemotherapy or acetaminophen use, before issuing a prescription.

Safety and follow-up

Safety note

The most commonly reported side effects are mild injection-site irritation, occasional headache, and mild gastrointestinal discomfort. Rare events include bronchospasm during IV administration in patients with reactive airway disease, and skin-tone changes with prolonged high-dose use. Patients are instructed to discontinue and contact the practice immediately if any breathing difficulty, rash, or unexpected reaction occurs. Follow-up consultations occur at the cadence determined by the prescribing physician.
