The FDA has begun an independent investigation after a July study revealed the presence of heavy metals in tampons from 14 companies. The study, published in Environmental International, found 16 chemicals, including lead, cadmium, and arsenic, in tampons, raising concerns about their safety.

Sen. Patty Murray (D-WA) initiated the investigation with a letter to the FDA urging action. “Millions of women use these products every day,” Murray said. “We must ensure their safety and address any concerns.”

The presence of heavy metals like lead and cadmium is concerning, as these toxins can cause kidney disease, cancer, and fertility problems. With up to 86% of women using tampons regularly, the risks associated with these chemicals are significant.

The study, however, did not confirm whether these metals are absorbed into the body during tampon use. The FDA’s investigation will focus on determining if these chemicals can be absorbed through the vaginal wall, which would pose greater health risks.

As the FDA works on a detailed response to Murray’s inquiry, many women are left with questions about the safety of a product they use frequently. The FDA’s investigation will seek to provide clarity and ensure that women’s health remains a priority.
