Disodium EDTA
Also known as: Edetate Disodium, EDTA, Ethylenediaminetetraacetic Acid Disodium Salt, Calcium Disodium EDTA, Na2EDTA
Effective Dosage
No established oral supplement dose; IV chelation used 3g per infusion in clinical trials
What the Science Says
Disodium EDTA is a synthetic chelating agent — a chemical that binds to metal ions like lead, calcium, and other heavy metals. In medical settings, it is given intravenously to treat heavy metal poisoning, such as lead toxicity in children, where it effectively lowers blood lead levels. It also appears in food products as a preservative and in topical antiseptic formulations as an antimicrobial helper ingredient.
What It Doesn't Do
Does not prevent heart attacks or reduce cardiovascular events — two large, rigorous clinical trials (TACT and TACT2) found no benefit for heart patients. Does not improve quality of life in heart disease patients. The original TACT finding of modest benefit was not replicated in the follow-up TACT2 trial. Does not 'detox' your arteries or reverse atherosclerosis in any proven way. Oral EDTA in supplements is not the same as IV chelation therapy used in hospitals.

Absorption & Bioavailability
Poor when taken orally — EDTA is poorly absorbed from the gut. Clinical chelation therapy is administered intravenously precisely because oral absorption is inadequate for therapeutic effect.
Red Flags to Watch For
- Oral EDTA supplements cannot replicate IV chelation therapy — the doses and delivery method are completely different
- IV EDTA chelation carries real risks including kidney damage, low calcium levels, and electrolyte imbalances
- TACT2 (2024) definitively failed to replicate the modest benefit seen in the original TACT trial — the evidence base for cardiovascular use has collapsed
- Found in 379 registered supplement products despite no proven oral benefit for any condition studied in clinical trials
- Marketing claims about 'arterial cleansing' or 'cardiovascular detox' are not supported by the clinical trial evidence
- Children are especially vulnerable to risks from unregulated chelation products — only use under strict medical supervision for confirmed heavy metal poisoning
