Chelation is a chemical process where a substance, called a chelator, binds to metal ions in the body. This binding forms a stable complex that can help remove harmful metals, such as lead or mercury, from the bloodstream. Chelation therapy is often used in cases of heavy metal poisoning. The chelation process can occur naturally in the body or be induced through medical treatments. Common chelators include EDTA and DMSA, which are administered through injections or oral medications. While chelation can be beneficial for detoxification, it should only be performed under medical supervision to avoid potential side effects.
