EDTA Chelation (Calcium Disodium EDTA (CaNa2EDTA))

Category: Detox & Antioxidant. Status: FDA Approved (lead poisoning) / Off-label.

A synthetic amino acid chelator used for heavy metal detoxification. FDA-approved for lead poisoning and investigated for cardiovascular disease (TACT trial). Binds divalent/trivalent metals for renal excretion.

How it works

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.

Key facts

  • Molecular weight: 374.27 Da (disodium EDTA)
  • Half-life: ~1.5 hours (IV)
  • Bioavailability: ~5% oral; 100% IV
  • Storage: Room temperature. Sterile vials.

Dosing overview

  • Typical dose: 1.5-3g IV over 1-3 hours
  • Frequency: Weekly or biweekly
  • Duration: 20-40 sessions
  • Route: Intravenous infusion

Reported benefits

  • Lead and heavy metal removal
  • Reduced cardiovascular events (TACT trial)
  • Arterial calcium removal
  • Reduced oxidative stress
  • Improved vascular function

Possible side effects

  • Mineral depletion (zinc, calcium, magnesium)
  • Kidney stress
  • Hypocalcemia (rapid infusion)
  • Fatigue
  • Headache
  • Burning at injection site

Research

  • TACT trial: EDTA chelation and cardiovascular events (2019): Chelation therapy reduced cardiovascular events by 18% overall and 39% in diabetic patients with prior MI over 5-year follow-up.
  • EDTA and heavy metal body burden (2021): 30 IV EDTA sessions reduced urinary provoked lead by 70% and cadmium by 45% in occupationally exposed workers.
