How to Use Glutathione

Complete guide to Glutathione dosing, administration, timing, and protocol recommendations.

Quick Overview

Glutathione is the body's main intracellular antioxidant, a tripeptide of glutamate, cysteine, and glycine (often written GSH). It is sold as oral, IV, topical, and inhaled products and marketed for everything from detox and immune support to skin lightening, but its real, evidence-backed role is as a redox buffer that neutralizes oxidative stress and supports liver detoxification. Some clinical evidence exists for specific uses, while many popular claims, especially IV skin whitening, rest on weak or risky data.

Dosing Guidelines

Common Dose

500-1000 mg daily (oral or liposomal)

Frequency

1-2x daily

Dose Range

250-2000 mg daily depending on form

Note: Liposomal forms show better absorption than standard oral. IV provides rapid increases but effects fade after ~2 months. N-acetyl cysteine (NAC) is an alternative to boost endogenous GSH production. Consider with vitamin C for enhanced recycling.

Administration Method

Oral, liposomal, IV, or subcutaneous

Best Time to Take

Morning on empty stomach, or evening

Absorption may be improved on empty stomach. Some prefer evening to support overnight detoxification and cellular repair processes.

Protocol Duration

Ongoing supplementation or 4-12 week courses

Possible Side Effects

Not everyone experiences these. Individual responses vary.

  • Generally well-tolerated
  • Oral: bloating, mild cramping, gas
  • Oral: loose stools in some users
  • IV: injection site reactions
  • IV: rare cases of hepatotoxicity reported
