A new study led by the University of California, Berkeley, and published in Environmental International evaluated the levels of 16 metals in 30 tampons from 14 brands sold across the USA (79%) and Europe (21%). The study found measurable concentrations of heavy metals in tampons, including lead, arsenic, and cadmium.
It is essential to emphasize that the test samples were found in truly low concentrations. This could be explained by the use of extremely low detection limits (MDLs) during testing, and as researchers suggest, the detected metals could be present due to systemic environmental pollution.
American researchers also mentioned that further research would be needed. The test samples were very small, and it is not yet possible to assess the extent to which (and if at all) metals at these concentrations could be absorbed into the body and contribute to any health problems.
However, we realize that this study has raised concerns about the use of tampons, and therefore we want to inform, reassure, and answer all questions from our customers. At Femvie, we welcome every new scientific publication that evaluates the safety of menstrual products. Honesty and transparency are very important to us, which is why we always share all information about the composition and origin of our products – and today will be no different.
Are Femvie tampons safe?
Manufacturers of intimate hygiene products are not required to disclose their exact composition, unlike food and cosmetics. Therefore, maximum caution is important when choosing tampons and pads. Our organic cotton tampons are certified according to the Global Organic Textile Standard (GOTS), which is the world's leading standard for textile processing, setting the bar for organic brands across various industries.
Independent third parties thoroughly test the entire supply chain before it undergoes GOTS auditing, meaning that even the purest organic cotton fibers are subjected to heavy metal testing. GOTS sets limit values for safe, low concentrations of these heavy metals, and we are pleased to announce that Femvie meets these limits.
GOTS certification guarantees:
- adherence to strict ethical requirements throughout the entire production process
- strict control of organic cotton cultivation and every subsequent step from the cotton field to the final product
- that the products contain no traces of GMOs, pesticides, heavy metals, or other harmful substances
- regular laboratory tests proving the absence of the above-mentioned substances
At the same time, FEMVIE tampons are regularly tested by the leading German independent testing agency Öko-Test and meet all strict criteria.
The study further suggests that a possible source of metals could be antimicrobial agents, which are often part of the production of intimate products. We can confirm that none of these substances are added to our tampons during the manufacturing process.
What are Femvie tampons made of?
Unlike conventional tampons freely available in drugstores, which may be exposed to pesticides or chlorine bleach during production, may be perfumed, and contain plastics and synthetic additives, Femvie tampons are made from 100% certified organic cotton. Nothing more. And it's no different with our pads. Pads are still the most popular form of menstrual protection. Femvie pads, like tampons, are made from 100% organic cotton, ensuring maximum comfort and protection.

100% safety, 100% comfort
Our pads and tampons are 100% safe for women's health. However, pure cotton also has many other advantages. Because they contain no synthetic substances or artificial dyes other than cotton, they are perfectly breathable, comfortable, and suitable even for the most sensitive skin.
Want to experience the difference for yourself? Switch to Femvie organic tampons and pads and experience a worry-free period.
