EDTA works as a chelator that will bind numerous heavy metals. It is not absorbed, but pulls toxins out of the blood and gradually "cleans out" the arteries. It is excreted by the kidneys, through the urine, when given by IV. It significantly improves nearly every modifiable cardiovascular disease risk factor. EDTA decreases tissue calcification, decreases plaque size (calcified plaque), and increases global blood flow. Side effects and allergies are extremely rare. If you read labels, you already know EDTA is added to many foods as an antioxidant preservative. Not only is it very safe, but most of us have already been exposed. EDTA is not absorbed orally, but will pass through the intestinal tract.
