Dimercaptosuccinic acid is an sulphur compound that is commonly used as a natural chelating agent.
Pure DMSA can be used as a food supplement for both humans and animals.
Chelation is the word used to describe the way certain ions and molecules bind with metal ions, a process which when carried out internally, leads to the expulsion metal ions from the body.
This can be useful to help remove toxic metal elements from the body such as lead, mercury and arsenic. While this process of removing toxic heavy metals from the body can be useful in detoxification, chelation also removes nutrient minerals from the body. For this reason metal chelation should always be used under the direct supervision of a healthcare professional as specific mineral supplementation is required.
