EDTA Chelation vs TUDCA
A side-by-side research comparison of EDTA Chelation and TUDCA across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | EDTA Chelation | TUDCA |
|---|---|---|
| Full name | Calcium Disodium EDTA (CaNa2EDTA) | Tauroursodeoxycholic Acid |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | FDA Approved (lead poisoning) / Off-label | OTC supplement / Investigational |
| 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. | Acts as a chemical chaperone that reduces endoplasmic reticulum (ER) stress, inhibits apoptosis, protects mitochondria, improves bile flow and solubility, and provides neuroprotective and cytoprotective effects. |
| Molecular weight | 374.27 Da (disodium EDTA) | 571.81 Da |
| Half-life | ~1.5 hours (IV) | Variable (enterohepatic recirculation) |
| Bioavailability | ~5% oral; 100% IV | Moderate oral |
| Typical dose | 1.5-3g IV over 1-3 hours | 250-500 mg per day |
| Frequency | Weekly or biweekly | 1-2x daily |
| Route | Intravenous infusion | Oral capsule |
