What’s Really in Your Tampons?
For decades, tampons have been the go-to menstrual product for millions of people. They’re convenient, discreet, and widely available—but are they safe?
A groundbreaking 2024 study from researchers at UC Berkeley and Columbia University just revealed that many tampons may contain toxic heavy metals like arsenic, lead, cadmium, and mercury. Yes, the same metals linked to cancer, infertility, neurological issues, and hormone disruption.
The most alarming part? These metals were found in all types of tampons, including organic and name-brand products, across both U.S. and international markets.
Why It Matters More Than You Think
Tampons are worn internally for hours at a time, and the vaginal wall is one of the most absorbent parts of the body. That means toxins found in menstrual products can make their way into your bloodstream more quickly and directly than through skin contact elsewhere.
“We found concentrations of all metals we tested for, including toxic metals like arsenic and lead,” said Dr. Jenni Shearston, lead author of the UC Berkeley study.
These metals are known to contribute to:
-
Cognitive damage
-
Hormonal disruption
-
Organ and reproductive system harm
-
Increased cancer risk
And here’s the kicker: there’s currently no regulation requiring tampon brands to test or disclose the presence of these metals.
How Do These Metals End Up in Tampons?
There are several possible sources:
-
Cotton grown in polluted soil or water
-
Fields located near industrial sites or chemical contamination
-
Manufacturing additives like whiteners, pigments, and antimicrobial agents
Regardless of how the metals get there, the result is the same: potentially toxic exposure through a product used by millions each month.
Meet Saalt: A Clean Revolution in Period Care
At Dwell Refine, we’re passionate about championing wellness and sustainability. That’s why we’re proud to partner with Saalt—a brand that’s redefining period care from the inside out.
The Saalt Story
Saalt began with a phone call.
When CEO and co-founder Cherie Hoeger learned that her aunt in Venezuela couldn’t find pads or tampons due to years of shortages, she immediately thought of her five daughters—and how fragile access to basic period care really is.
“Our dependence on disposables kept me up at night,” Cherie said. “There had to be a better way.”
That call sparked a movement. Within months, Cherie was sourcing reusable products for friends and family. But when she couldn’t find any that met her standards, she started designing her own.
In 2018, Saalt was born, with a mission to create high-performance, reusable period and body care products that are better for both bodies and the planet.
