In August 2024, researchers at Columbia University published a study that found measurable concentrations of 16 metals in multiple brands of tampons. The study evaluated levels of metals like cadmium, manganese, and arsenic in 30 tampons across 14 different brands. The study concluded that using tampons may be a potential source of metal exposure. We covered this publication in JULY 2024 before it was released! In response to the study, the FDA launched an investigation that includes 3 parts: 1. An independent literature review to learn more about data available regarding the presence of chemicals in tampons and possible health effects , 2. A laboratory study to evaluate metals in tampons and potential exposure people may experience when using them, and 3. Toxicity testing to identify potentially harmful substances and assess the risk of those substances being absorbed by the body. The literature review has been completed and was released by the FDA on Dec 23, 2024. Listen in for details.
