While animal and in vitro studies suggest zeolite may have anti-cancer properties, there is no proof that zeolite helps prevent or fight cancer, as no human studies are published, according to Memorial Sloan Kettering Cancer Center. Zeolite is not an approved anti-cancer drug, and zeolite supplements are not approved as safe or effective.
The mineral zeolite contains aluminum and silicone compounds, states Memorial Sloan Kettering Cancer Center. Excluding the use of supplements, zeolites are used in detergents, as drying agents and in air conditioners. Supplements containing zeolite are marketed as a cure for cancer, autism and herpes. The Food and Drug Administration has submitted warning letters to the distributors of these products that contain misleading labeling. Side effects associated with zeolites include fibrosis, pneumoconiosis and mesothelioma. Inhaling zeolite powder is linked to causing cancer.
Individuals who are taking any medications should not take zeolite, as it binds with other substances and neutralizes stomach acids, causing improper absorption of medication, explains Memorial Sloan Kettering Cancer Center. Additionally, individuals who are transplant patients or those taking medications to suppress the immune system should not take zeolite, as zeolites can cause rejection. Zeolites also have an antioxidant effect and interfere with chemotherapy drugs, as well as decreasing the effectiveness of antibiotics and drugs that contain iron.
