Ergothioneine vs Glutathione (IV/IM)
A side-by-side research comparison of Ergothioneine and Glutathione (IV/IM) across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Ergothioneine | Glutathione (IV/IM) |
|---|---|---|
| Full name | L-Ergothioneine | L-Glutathione (Reduced, Injectable) |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | OTC supplement | Compounded / Prescription |
| Mechanism | Accumulates via the OCTN1 transporter in mitochondria and other high-stress cellular compartments, where it scavenges reactive oxygen species, chelates metals, protects DNA and mitochondria, and preserves other antioxidants. | Directly conjugates with toxins, heavy metals, and reactive oxygen species via glutathione S-transferases. Regenerates vitamins C and E. Maintains thiol redox status. Supports Phase II liver detoxification. |
| Molecular weight | 229.30 Da | 307.32 Da |
| Half-life | Very long (weeks; retained in tissue) | ~2-3 hours (IV bolus) |
| Bioavailability | Good oral via OCTN1 transporter | 100% (IV); ~60% (IM); ~5-10% (oral) |
| Typical dose | 5-25 mg per day | 600-2000 mg IV push or 200-600 mg IM |
| Frequency | Once daily | 1-3x weekly |
| Route | Oral capsule | Intravenous push or intramuscular injection |
