View press release

Public Citizen petitioned the Food and Drug Administration (FDA) to ban the sale of all dietary supplements containing the chemical cesium chloride or any other cesium salt because they present a significant and unreasonable risk of illness or injury. Cesium can cause serious, life-threatening adverse cardiovascular events, and the FDA has declared cesium chloride to be unsafe for human use. These products have been promoted as treatments for cancer, despite the lack of evidence demonstrating cesium’s proposed cancer-treating properties.
