EDTA (Ethylenediaminetetraacetic acid) is an amino acid that binds to metals to allow them to pass through and out of the body. Due to this ability, intravenous EDTA has been used to treat various types of metal poisoning and other illnesses.

Prevents Free Radical Reactions

EDTA binds with certain metals involved in free radical reactions, thus reducing free radical damage. This helps prevent cholesterol oxidation, which promotes atherosclerosis.

Increased Blood Flow to Bodily Organs

Intravenous EDTA binds to calcium in plaque and the walls of the artery. This decreases the amount of calcium outside of the cells, which makes arterial walls more flexible. Greater elasticity of the arterial walls allows more blood to be delivered to organs.

Increased Tissue Flexibility

EDTA allows connective tissue to be more flexible because it reduces the coupling of disulfide and minerals.

Reduce Blood Clot Build-Up

EDTA reduces the production of platelets and blood clots that could block an artery by balancing the levels of prostacyclin and thromboxane.

Increases Flexibility of Red Blood Cells

EDTA makes red blood cell membranes more liquefied, which allows them to move through small capillaries more easily and increases oxygen delivered to tissues throughout the body.

Treats Metal Poisoning

Since EDTA binds to heavy metals in the body it can allow poisonous metals such as lead to be effectively eliminated from the body.
