DMSA (DiMercapto Succinic Acid)

Oral Chelation for Arsenic, Cadmium, Lead and Mercury

DMSA (meso-2,-3-dimercaptosuccinic acid) is a water soluble sulfhydryl-containing metal chelator that binds to arsenic, cadmium, lead and mercury. It is effective when taken orally and has been used since the 1950's as chelator of heavy metals in the body.

According to Ward Dean, M.D., "Research confirms this substance’s efficacy and safety, and supports its use as the premier oral metal chelator for mercury and its efficacy for other heavy metals. DMSA’s water-solubility, oral dosing, large therapeutic window and low toxicity make it the chelator of choice for many applications."

Although DMSA has a low toxicity, side effects can include rash, nausea or vomiting. Discontinue use of product and consult an holistic physician if these symptoms occur. Do not use during pregnancy or childhood except under the supervision of a physician.

Dr. Myatt's Note: This is the chelator I recommend for use with a 6-hour urine mineral test to detect the presence of heavy metals in the body. When using DMSA on an ongoing basis for oral chelation, please use under the guidance of an holistic physician.
