Zeolite: Investigation of the Effectiveness and Safety as an Oral Chelating Agent for Heavy Metals. A comparison between different commercially available preparations

This case study was performed to evaluate the effectiveness of clinoptilolite zeolite (“zeolite” herein) as an oral chelating agent for heavy metals. Zeolite is a hydrated aluminosilicate with symmetrically stacked alumina and silica tetrahedra which result in an open and stable three dimensional honey comb structure with a negative charge. The negative charge within the pores is neutralized by positively charged ions (cations) such as calcium. Historically, zeolite has been used as a commercial absorbent, and more recently in the dietary supplement industry as a detoxifier.
