EDTA Chelation Research Guide

Full name: Calcium Disodium EDTA (CaNa2EDTA)

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 EDTA Chelation 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.

Dosing Protocol

• 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

Potential Side Effects

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

2. 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.
