EDTA Chelation vs Quercetin
A side-by-side research comparison of EDTA Chelation and Quercetin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | EDTA Chelation | Quercetin |
|---|---|---|
| Full name | Calcium Disodium EDTA (CaNa2EDTA) | Quercetin (Flavonoid Senolytic) |
| 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. | Selectively induces apoptosis in senescent cells by inhibiting pro-survival (SCAP/BCL) pathways, especially when paired with dasatinib. Also scavenges free radicals, inhibits mast-cell histamine release, and modulates NF-kB inflammatory signaling. |
| Molecular weight | 374.27 Da (disodium EDTA) | 302.24 Da |
| Half-life | ~1.5 hours (IV) | ~11-28 hours |
| Bioavailability | ~5% oral; 100% IV | Low; improved by phytosome/bromelain formulations |
| Typical dose | 1.5-3g IV over 1-3 hours | 500-1000 mg per day (daily) or high-dose pulsed (senolytic) |
| Frequency | Weekly or biweekly | Daily or intermittent |
| Route | Intravenous infusion | Oral capsule |
