DMSA is the organosulfur compound with the formula HO2CCH(SH)CH(SH)CO2H. This colorless solid contains two carboxylic acid and two thiol groups, the latter being responsible for its mildly unpleasant odour. It occurs in two diastereomers, meso and the chiral dl forms. The meso isomer is used as achelating agent. The acid is most often used as a treatment for heavy metal toxicity, and is a water soluble and non-toxic substance.

DMSA is a chelator that is able to bind to metals in the body which can then be expelled through the urine. It will reduce levels of toxic metals like lead and arsenic but also essential metals like copper and zinc. Supplements are usually prescribed with DMSA to ensure levels of essential metals are not diminished along with toxic ones. DMSA capsules can be compounded in multiple strengths to meet each individual patient's needs.
