Chelation refers to the use of a substance that helps remove toxic minerals from the body. This is achieved through the use of a chelator such as EDTA, DMPS, DMSA or vitamin C. EDTA (ethylene diamine tetra-acetic acid) is the most common agent used in chelation therapy for cardiovascular disease at the clinic.
Chelation is a chemical reaction that results in a bond being formed between a metal ion and an organic molecule. The resulting complex, the metal bound to molecule, is called a chelate. It contains one or more rings of atoms in which the metal ion is so firmly bound it cannot escape. This allows the metal ion to be transported in the same manner as a prisoner, first handcuffed, then moved from one location to another.
In the presence of aging and disease, the cells ability to move metal ions through the system and eliminate them when they are in excess becomes progressively impaired. This is especially true for calcium.
Calcium has vital functions in the human body. But with chronic inflammation, calcium can get deposited into areas where it shouldn’t be. With hardening of the arteries or atherosclerosis, the walls of the blood vessels become stiffer as the disease progresses. The artery then has difficulty expanding and contracting to receive and push forward the blood. A decreased blood supply will over time lead to decreased cellular function. EDTA can move excess calcium out of the body.
Chelation has been scientifically proven to be effective in acute heavy metal poisoning. It has been used in clinical practice for over 30 years as a treatment for chronic low-level exposure to heavy metals such as lead and cadmium that, when elevated, are toxic to the human body. The bound substance is transported through the blood stream where it is then excreted from the body via the kidneys.
EDTA is given in a dose of 2000-3000 mg (adjusted to body weight, age and kidney function) intravenously along with a mixture of vitamins and minerals such as vitamin C, B complex, bicarbonate and magnesium. The solution is infused slowly over a 2 to 3 hour period. The half life for EDTA in the body is one hour (ie one-half is removed and filtered through the kidneys into the urine after one hour. Another half of what is left is removed after one more hour etc. Within 24 hours 99% of the EDTA is gone from the body).
Research on EDTA has shown the following positive effects:
- EDTA lowers blood calcium and thus stimulates the production of parathormone from the parathyroid glands. This mild pulse of parathormone is responsible for the removal of calcium from abnormal locations (e.g. arteries) and the deposition of calcium in locations (e.g. bones) where it should be. This accounts for the mild recalcification of osteoporotic bones seen with EDTA.
- EDTA stimulates the enlargement of small blood vessels, so that they serve the purpose of collateral circulation around a blockage, rendering the blockage irrelevant.
- EDTA controls free radical damage due to lipid peroxidation by serving as a powerful antioxidant.
- EDTA can remove abnormally located metal ions such as copper and iron that accumulate with age.
- EDTA removes lead, cadmium, arsenic and other metals restoring enzyme systems to their proper functions.
- EDTA enhances the integrity of cellular and mitochondrial membranes
- EDTA helps re-establish prostaglandin hormone balance. Prostaglandins are responsible for the balancing act between contraction and relaxation of arterial walls and between clotting and the free flow of blood. Prostaglandins are produced from fatty acids, therefore lipid peroxidation upsets the balance of these vital hormones. EDTA chelates out the catalyzing metallic co-enzymes and thus inhibits lipid peroxidation, also serving the same function as an antioxidant.
- EDTA reduces the tendency of platelets to cause coagulation too readily. This tends to prevent inappropriate thrombosis, which blocks coronary arteries during a heart attack.
- EDTA increases tissue flexibility by uncoupling age-related cross-linkages that are responsible for loss of skin tone and for wrinkling.
Clients report increased energy, decreased chest pain, increased activity tolerance, improved circulation in legs, warmer feet, less shortness of breath, the ability to walk long distances comfortably and improved brain function. Very often blood test results return to the normal range. After a series of chelation treatments, many persons have required less medication and avoided bypass surgery.
Most people feel well through the treatment. Some experience a drop in blood sugar levels so clients are advised to eat before and during a treatment. Sometimes the IV site will ache. This is relieved with the application of a heat pad.
After a treatment, the client may feel tired, light-headed or have a headache. These usually resolve by the next day. This is a result of the heavy metal detoxification process. Others immediately feel energized and clear-headed.
