Heavy Metal Contamination in Tampons & Your Health Options
It is estimated that over 100 million cisgender women in over 120 countries use tampons during their menstrual cycle. Tampons, typically made from cotton and/or rayon, are generally considered safe menstrual products. However, a recent study conducted by researchers at the UC Berkeley School of Public Health has raised concerns about the presence of heavy metals in tampons, which could pose health risks.
The Study: Heavy Metals in Tampons
The study, published in the journal Environment International, evaluated levels of 16 heavy metals in tampons from 14 different brands purchased in the U.S. and the U.K. These metals included arsenic, barium, calcium, cadmium, cobalt, chromium, copper, iron, manganese, mercury, nickel, lead, selenium, strontium, vanadium, and zinc. Researchers found measurable concentrations of all 16 heavy metals tested, with lead being present in 100% of the tampons.
Differences Between Organic and Non-Organic Tampons
The study also compared heavy metal concentrations based on various factors, such as the country of purchase (U.S. vs. U.K.), store-brand vs. name-brand, and organic vs. non-organic. Non-organic tampons had the highest concentration of lead, while organic tampons contained the highest levels of arsenic. Despite these findings, the study did not provide clear recommendations on which type of tampon is safer, as heavy metals were found in all tampons tested.
Where Do These Contaminants Come From?
The presence of heavy metals in tampons can be traced back to various sources within the agricultural and manufacturing processes. Understanding these sources helps highlight the importance of stricter regulations and better practices.
Contaminated Soil:
Heavy metals such as mercury, lead, and cadmium are commonly found in contaminated soil. Agricultural practices that do not manage soil health can lead to the uptake of these metals by plants. Cotton and other plants used in tampon production can absorb these metals, which then end up in the final product.
Industrial Pollution:
Industrial activities, including mining, manufacturing, and waste disposal, contribute significantly to environmental contamination. These activities release heavy metals into the air, water, and soil, which can then be absorbed by plants grown in these environments.
Pesticides and Fertilizers:
The use of certain pesticides and fertilizers can introduce heavy metals into the soil. Over time, these substances can accumulate in the soil and be taken up by plants, including those used to make tampons.
Manufacturing Processes:
During the manufacturing of tampons, contamination can occur if the raw materials or production equipment are not properly managed. Metals can leach into the products during various stages of processing, from harvesting the raw materials to packaging the final product.
Water Sources:
Irrigation with contaminated water can also introduce heavy metals to crops. Industrial runoff and poor water management practices can lead to heavy metal contamination of water sources used for agricultural purposes.
Symptoms of Heavy Metal Toxicity
Exposure to heavy metals can lead to a range of health issues. Symptoms of heavy metal toxicity may include:
Chronic fatigue
Headaches
Digestive issues
Muscle and joint pain
Cognitive difficulties (e.g., memory problems, confusion)
Mood disturbances (e.g., anxiety, depression)
Immune system dysfunction
Testing for Heavy Metal Toxicity
If you suspect heavy metal exposure, several testing options are available and can be ordered by a naturopathic or functional medicine doctor. Testing for exposure to metals involves analyzing samples such as blood, urine, saliva, or hair. Various testing panels are available and offer comprehensive assessments of metal exposure and its effects on the body.
Metal Testing Type Overview:
Blood tests: Measure the current level of heavy metals in the bloodstream.
Urine tests: Detect the excretion levels of heavy metals.
Hair analysis: Provides a long-term view of heavy metal exposure.
Fecal tests: Evaluate the presence of heavy metals being eliminated through the digestive tract.
Here are some examples of heavy metals tests that are available:
Doctor's Data Hair Elements: This test uses a hair sample to evaluate recent and ongoing exposure to toxic metals and assesses the status of nutrient elements in the body.
Genova's Metabolomix+ Add-On: Toxic Element Clearance: A urine sample is analyzed for 20 potentially harmful toxic metals, providing insights into the body's ability to clear these elements.
Quicksilver's Metals Combo Test: This comprehensive test examines urine, serum, hair, and whole blood samples to determine exposure to toxic elements, deficiencies in nutrient elements, and levels of inorganic and methyl mercury.
Mosaic Diagnostics' Metals Red Blood Cell: A blood sample is tested to measure the presence and levels of elements critical to red blood cell function.
Genova's Elemental Analysis: This test processes a blood sample to identify levels of minerals and toxic elements, helping to determine the extent of exposure.
In addition to metals testing, a thorough evaluation includes a detailed health history covering diet and lifestyle practices, and an environmental history to pinpoint potential sources and types of exposure, such as ingestion, absorption, or inhalation.
Treatment for Heavy Metal Toxicity
Treating heavy metal toxicity involves several approaches that are highly tailored to your individual heavy metal burden, as well as which metals you test the highest for. These detox protocols can range from very intensive to a gentle supportive detox depending on your symptoms, test results, and personal preference.
Chelation therapy: Uses chelating agents to bind heavy metals and facilitate their excretion from the body.
Detoxification support: Enhances the body's natural detoxification processes through nutritional support, hydration, and liver function optimization. This may include supplements such as glutathione, sea kelps, and herbs such as hawthorne and milk thistle.
Dietary changes: Incorporates foods rich in antioxidants and nutrients that support detoxification, such as leafy greens, garlic, and cilantro.
Lifestyle modifications: Reduces further exposure to heavy metals by avoiding contaminated products and environments.

A Call to Action for Safer Tampon Guidelines
The findings of the UC Berkeley study underscore the need for stricter guidelines and better testing practices for tampons. Consumers are encouraged to reach out to tampon brands to inquire about their testing for toxic metals and to choose products with the lowest levels of harmful substances. Exploring alternative menstrual products, such as pads, menstrual underwear, or menstrual cups and discs may be beneficial, though these products can also contain harmful additives.
As awareness of the potential risks associated with heavy metals in tampons grows, it's crucial to continue research and advocate for safer menstrual products. Women should remain informed and proactive about the products they use, ensuring their choices support their health and well-being.
