Bio-Chelat Environmental Defense™ is a patented chelator based on polyaminopolycarbonicacid (EDTA) and physiological digestible salts. The most frequent heavy metals found in our bodies are mercury, lead, copper, cadmium, nickel, aluminium and manganese. The heavy metal ions, mostly lodged in the kidneys, the liver and the brain, will be pulled from the body tissue into the blood stream and excreted via the kidneys and stool.
