A recent scientific study has sparked conversations about menstrual products after researchers detected multiple metals in commercially available tampons. The findings have raised understandable questions about menstrual health, product safety, and whether tampon users should be concerned.
While the research is important, it’s equally important to understand what the study did—and did not—show. Detecting a substance in a product does not automatically mean it poses a health risk. More research is needed to determine whether these metals are absorbed by the body and, if so, whether they occur at levels that could affect health.
Here’s what the latest research tells us.

Researchers published in Environment International analyzed commercially available tampons sold in the United States to determine whether they contained naturally occurring or environmental metals.
The study tested for 16 metals, including:
Researchers also compared products with different absorbencies and from multiple manufacturers.
The goal of the study was to determine whether these metals were present—not to measure whether they enter the body or cause health effects.
The researchers detected measurable amounts of all 16 metals in the tampons they tested.
Some metals, including zinc, were found at relatively higher concentrations. The study also detected lead and arsenic, which attracted significant public attention because both are known to be toxic at sufficient levels of exposure.
However, finding a substance in a product is only one part of understanding potential health risks. The presence of a metal does not necessarily mean it can be absorbed by the body in meaningful amounts.
The researchers themselves noted that additional studies are needed to determine whether exposure occurs during normal tampon use.
At this time, health experts are urging caution—not panic.
The study provides valuable information about what was detected in tampons, but it does not demonstrate that using tampons is harmful or that the detected metals are absorbed into the body at levels that pose a health risk.
Several important questions remain unanswered, including:
Until further research is available, there is not enough evidence to conclude that tampon use increases the risk of disease because of these findings.
Although the study does not establish a direct health risk, it highlights the importance of continued research into menstrual products.
Millions of people use tampons throughout their reproductive years, making product safety an important area of scientific investigation.
The findings also contribute to broader conversations about transparency in menstrual product manufacturing and the need for continued research into women’s health.
Historically, many aspects of menstrual and reproductive health have received less scientific attention than other areas of medicine. Studies like this help identify questions that deserve further investigation.
There is no single menstrual product that is right for everyone.
Options include:
Each product has its own advantages and considerations related to comfort, convenience, cost, lifestyle, and personal preference.
If you have concerns about a menstrual product or experience irritation, discomfort, or unusual symptoms, speak with your healthcare provider.
Your menstrual cycle can provide valuable information about your overall reproductive health.
Paying attention to cycle length, flow, symptoms, and changes over time can help you better understand your body and identify concerns worth discussing with a healthcare provider.

The recent study identifying metals in tampons is an important step in understanding menstrual product safety, but it should be interpreted carefully.
Researchers confirmed the presence of multiple metals in the products they tested. However, the study did not determine whether these metals are absorbed by the body or whether they pose a health risk during normal use.
As additional research becomes available, scientists and health regulators will continue evaluating what these findings mean for menstrual product safety.
For now, consumers should rely on evidence-based information rather than alarming headlines and speak with a healthcare provider if they have concerns about menstrual health or product use.
Yes. Researchers detected multiple metals, including lead, arsenic, zinc, and others, in the tampon samples they tested.
Not necessarily. The study identified the presence of metals but did not determine whether they are absorbed by the body or whether they pose a health risk during normal use.
Current evidence does not support the conclusion that tampons are unsafe because of this study alone. If you have concerns, discuss them with your healthcare provider and choose the menstrual products that best suit your needs.
Researchers still need to determine whether the metals detected in tampons can be absorbed through vaginal tissue and whether repeated exposure has any meaningful effect on long-term health.
Tampons have been widely used since their creation in 1931, yet in 2024, experts say they might not be as safe as we thought. In a recent study by a group of scientists from the United States published in Environment International, tampons from top-rated brands were found to contain harmful metals in their products.
This has become a large conversation in the area of reproductive health, as individuals who are menstruating are now at risk of exposure to harmful and toxic metals.
This review summarizes the main findings of this paper and why there is concern for the preservation of reproductive health.
What Did They Look For?
There is little to no research on the presence of metals and metalloids in tampons and how their presence could affect women’s reproductive health. This research investigated the presence of the following sixteen metals in brand-name tampons:
arsenic, barium, calcium, cadmium, cobalt, chromium, copper, iron, mercury, manganese, nickel, lead, selenium, strontium, vanadium, and zinc.
Tampons of different absorbency levels (i.e. regular, super) were examined for the presence of metals and their concentrations. The cause for concern is upon the discovery of large concentrations of these harmful metals. This is because this would mean individuals who use tampons when menstruating are unknowingly putting themselves at risk of exposure to these metals and possibly causing damage to their reproductive organs and overall wellbeing.
What Did They Find?
From this study, it was found that all of these metals were present in all the tampons. Specifically, zinc, arsenic and lead were present in higher concentrations than the rest. These findings are alarming, especially the large presence of arsenic and lead as these metals are toxic to the human body. The other metals were present but in trace amounts. Trace metals are small amounts of metal that are present in a product. Typically, trace metals are present in many items such as cereals, and are not cause for large concern regarding overall health.
This study is groundbreaking, as it is one of the first published studies to discover these metals in tampons.
Should I Be Concerned?
When it comes to women’s reproductive health, this study has brought a new conversation to the table. Tampons are generally not the healthiest and safest feminine hygiene product yet they have become widely popular due to their discreteness and comfortability.
To completely rule out tampons as a safe option, more research will need to be conducted on the transfer of these metals onto the human body and the effects.
