- Oral Reduced GSH (capsule/tablet)
- 2,000–3,000mg daily
- 10–20%
- 60–90 minutes
- Low cost, widely available
- Requires very high doses, inconsistent absorption, gastric breakdown
- Least efficient option. Only viable if liposomal/acetylated forms unavailable
- Liposomal Glutathione
- 500–1,000mg daily
- 60–80%
- 45–60 minutes
- High bioavailability, bypasses first-pass metabolism, stable in GI tract
- Higher cost than oral GSH, requires refrigeration post-opening
- Gold standard for oral supplementation. Best balance of efficacy and practicality
- Acetylated Glutathione (S-acetyl-L-glutathione)
- 50–70%
- Stable at room temperature, crosses cell membranes intact, good oral bioavailability
- Limited clinical trial data vs liposomal, slightly lower bioavailability than liposomal
- Strong alternative to liposomal. Ideal for travel or when refrigeration isn't practical
- Intravenous Glutathione
- 600–1,200mg per session, 2–3x weekly
- ~100%
- Immediate
- Direct delivery, 100% bioavailability, rapid plasma concentration increase
- Requires medical supervision, sterile preparation, injection site reactions possible
- Most effective for acute detoxification or heavy metal protocols. Not for routine use
- Sublingual Glutathione
- 200–500mg daily
- 30–50% (estimated)
- 15–30 minutes
- Bypasses first-pass metabolism, faster absorption than oral
- Limited clinical data, mucous membrane irritation in some users, inconsistent absorption
- Emerging option. Theoretically sound but lacks head-to-head trials vs liposomal
