Key Takeaway
Review of clinoptilolite zeolite found some evidence for heavy metal binding in animal studies, but limited human research and potential for binding essential minerals warrants caution.
Summary
This comprehensive review examines the safety and medical applications of clinoptilolite zeolite, the form most commonly used in supplements.
While in vitro and animal studies show zeolite can bind heavy metals and certain toxins, human clinical evidence remains limited. The review notes concerns about potential binding of essential minerals and the need for more rigorous human trials.
