A study led by University of California Berkeley researchers and published in the August issue of Environment International evaluated levels of 16 metals in 30 tampons from 14 brands and 18 product lines sold across the US and Europe. The study found measurable concentrations of all 16 metals assessed, including toxic metals such as lead, arsenic and cadmium. In response to this alarming report, and with concern for full transparency and to help to allay consumer concerns, Natracare, the world’s leading brand of sustainable period care products, is making their independent testing publicly available.”

As a precautionary principle and as part of Natracare’s annual organic certification audit, tests for detecting heavy metals as well as PFAS are commissioned to a third-party accredited laboratory,” said Natracare Founder Susie Hewson. “These test results of our GOTS certified organic cotton tampons show no detectable traces of heavy metals or other chemicals of concern and are publicly available to offer peace of mind and full transparency.”

The new study published in Environment Internationalhighlights the presence of toxic metals in many tampons, raising concerns about potential health risks—something Natracare has given voice to for over three decades. “We believe people who bleed deserve safe, natural options for their periods,” Hewson said. “Thirty years ago, we were concerned by what certain companies put in period products, and we actively supported Congresswoman Carolyn Maloney’sTampon Safety and Research Act of 1997, now called the Robin Danielson Menstrual Product and Intimate Care Product Safety Act, for this very reason. It was our outrage that led to the founding of Natracare and the last 34 years of campaigning for safe period care.”

“The findings of this study are tremendously valuable because they will not only drive pressure for better regulatory measures, but also give people the information they need to choose what is best for their bodies and to hold more companies accountable to doing the same, both of which we have advocated for since our inception in 1989,” said Hewson.

As a campaigning brand for over 30 years, Natracare’s founding philosophy has always been to make certified organic 100% cotton tampons to reduce unnecessary exposure to chemicals of concern. Natracare has earned several certifications for exceptional environmental and ethical quality. In fact, Natracare tampons are certified to the Global Organic Textiles Standard (GOTS)—the gold standard for organic tampons—adding an extra precaution to guarantee the safety and quality of Natracare tampons. The GOTS certification underscores Natracare’s commitment to health and sustainability.

GOTS has stringent regulations for testing and controlling residuals. The standard clearly defines “explicitly banned or prohibited for environmental and/or toxicological reasons in all processing stages of GOTS Goods,” and further states that “inputs shall be ‘heavy metal free.’ Impurities shall not exceed the limit values as defined.”

“Just as we fought for regulatory authorities to require tampon manufacturers to test for dioxin residuals, we continue to strongly support the need for regulations that require manufacturers to test accordingly for chemicals of concern and heavy metal residuals in tampons, for transparency,” said Hewson. “We share consumers’ concerns for the discovery of heavy metals found in some brands of tampons, and we fully support regulatory intervention of some determination to measure and establish levels of chemicals of concern and heavy metals detected in tampons. Such a framework exists for cosmetics; why not tampons?”

Helen Lynn, Environmenstrual campaign manager for Women’s Environmental Network (WEN), responded, “Dozens of metals, including lead, arsenic and cadmium, were found in tampon samples from brands purchased in the UK, US and the EU. The researchers tested both organic and non-organic samples but do not list the brands chosen.”

“We are exposed to background levels of metals through our diets and pollution,” Lynn continued, “but the researchers suggested additives to tampons like antimicrobials and/or anti-odor chemicals, whiteners or lubricants could be the source. Zinc and calcium were found in high concentrations, and these can be used for odor control, lubrication and as antimicrobial agents. But none of the tampons studied listed zinc as an additive, even those purchased in New York State, where there is a requirement, by law, to list all ingredients.”
