Activated Charcoal vs EDTA Chelation
A side-by-side research comparison of Activated Charcoal and EDTA Chelation across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Activated Charcoal | EDTA Chelation |
|---|---|---|
| Full name | Activated Charcoal (Binder) | Calcium Disodium EDTA (CaNa2EDTA) |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | OTC / Medical device | FDA Approved (lead poisoning) / Off-label |
| Mechanism | Adsorbs toxins via van der Waals forces on its massive activated surface area. Binds mycotoxins (aflatoxin, ochratoxin), bacterial endotoxins (LPS), pesticide residues, and various organic compounds, preventing GI absorption. | 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. |
| Molecular weight | 12.01 Da (elemental carbon) | 374.27 Da (disodium EDTA) |
| Half-life | Not absorbed - passes through GI tract | ~1.5 hours (IV) |
| Bioavailability | Not absorbed systemically (GI binder only) | ~5% oral; 100% IV |
| Typical dose | 500-1000 mg | 1.5-3g IV over 1-3 hours |
| Frequency | 1-2x daily away from meals/supplements | Weekly or biweekly |
| Route | Oral capsule or powder | Intravenous infusion |
