EDTA Chelation vs Ergothioneine
A side-by-side research comparison of EDTA Chelation and Ergothioneine across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | EDTA Chelation | Ergothioneine |
|---|---|---|
| Full name | Calcium Disodium EDTA (CaNa2EDTA) | L-Ergothioneine |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | FDA Approved (lead poisoning) / Off-label | OTC supplement |
| Mechanism | Hexadentate chelator forming stable complexes with Pb²⁺, Cd²⁺, Hg²⁺, and Ca²⁺ from arterial plaque. Metal-EDTA complexes are water-soluble and excreted renally. Also reduces oxidative stress from heavy metal catalyzed Fenton reactions. | 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. |
| Molecular weight | 374.27 Da (disodium EDTA) | 229.30 Da |
| Half-life | ~1.5 hours (IV) | Very long (weeks; retained in tissue) |
| Bioavailability | ~5% oral; 100% IV | Good oral via OCTN1 transporter |
| Typical dose | 1.5-3g IV over 1-3 hours | 5-25 mg per day |
| Frequency | Weekly or biweekly | Once daily |
| Route | Intravenous infusion | Oral capsule |
