Calcium disodium (EDTA)

Calcium disodium EDTA is an odorless crystalline powder with a slightly salty flavor. It’s a popular food additive, used as a preservative and flavoring agent.

Calcium disodium EDTA works as a chelating agent. Chelation therapy uses calcium disodium EDTA to treat metal toxicity, such as lead or mercury poisoning. The substance binds to the excessive metal in your blood, which is then excreted through urine.
