DMPS
DMPS (Dimercaptopropane Sulfonate or 2,3-Dimercaptopropane Sulfonic Acid) is a sulfur-based, water-soluble chemical chelation agent. DMPS has been used for decades in Europe as a treatment for heavy metal intoxication and although primarily used as a chelator for mercury toxicity, it seems to have an affinity for pulling out various other metals (both harmful and helpful) as well. Available as a finished drug in Europe, DMPS is only available in the United States as a bulk chemical to be compounded by a pharmacist when (and only when) prescribed by a physician. Due to safety concerns and other risk factors, DMPS has not been approved by the Food and Drug Administration (FDA) and as such is still being researched and tested.

DMSA

DMSA (Meso-2,3-Dimercaptosuccinic Acid; also Chemet and Succimer) is another water-soluble, low-toxicity chemical chelation agent that contains sulfur. DMSA is primarily used as a chelator for lead (in children) and mercury toxicity, but to a lesser extent it also binds to other heavy metals in the body (such as arsenic and cadmium) as well as other essential elements. DMSA is usually administered orally and is available by prescription only. DMSA is thought to be a much safer chelation alternative than DMPS.

EDTA

EDTA (Ethylene Diamine Tetra-Acetic Acid) is an artificial amino acid that has been effective as a heavy metal chelating substance. EDTA first became known for its lead-chelating properties over 50 years ago, and today is an FDA-approved treatment for lead, mercury, aluminum and cadmium toxicity. EDTA also seems to help restore blood vessels blocked by calcium and other arterial plaque components. Because it may also remove certain minerals and other essential elements from the body, it is usually administered with supplemental vitamins and minerals. EDTA is considered essentially non-toxic with few major side effects.

NDF and NDF-Plus

NDF (Nanocolloidal Detox Factors) is a sulfur-less dietary supplement made from organic raw and whole food products whose main use is heavy metal detoxification and immune system support. (NDF-Plus is a stronger version that also contains fulvic acid complexes and other concentrates not provided in regular-strength NDF.) NDF binds to heavy metals using the alga chlorella, making its removal process different than that of other chelating agents. It also differs from most other chelators in that it eliminates metals predominantly through the urine, whereas the other chelators' primary elimination routes are through the bowels.
