Heavy metals are, unfortunately, present in the air, water, and food supply.
of severe acute lead, mercury, arsenic, and cadmium poisoning are rare; however,
when they do occur an effective, non-toxic treatment is essential. In addition, chronic,
low-level exposure to lead in the soil and in residues of lead-based paint; to mercury in
the atmosphere, in dental amalgams and in seafood; and to cadmium and arsenic in
the environment and in cigarette smoke is much more common than acute exposure.
Meso-2,3-dimercaptosuccinic acid (DMSA) is a sulfhydryl-containing, water-soluble,
non-toxic, orally-administered metal chelator which has been in use as an antidote to
heavy metal toxicity since the 1950s. More recent clinical use and research substantiates
this compound’s efficacy and safety, and establishes it as the premier metal chelation
compound, based on oral dosing, urinary excretion, and its safety characteristics
compared to other chelating substances.
