Are Tampons Toxic?
If you’re like most of us, you probably haven’t spent a lot of time thinking about what’s in your tampons. But, as Dr. Maggie Ney, the co-director of the Women’s Clinic at the Akasha Center in Santa Monica explains, it’s not quite that simple. Because the vaginal walls are incredibly permeable, any chemicals in a tampon can make it to the bloodstream, which isn’t great when we’re talking about tampons that you’ll use a lot of in your lifetime. Below, she explains more. (For more from Ney, see her piece for goop on perimenopause.)
A Q&A with Maggie Ney, N.D.
Can’t our bodies just eliminate the unwanted chemicals and toxins?
It would be great if there were a stop sign in our body for toxins not to penetrate. Our bodies are incredible and we have very sophisticated detoxification pathways in our liver to process and eliminate environmental toxins and chemicals. And it’s not just our liver that is constantly cleansing and detoxing; our kidneys, skin, lungs, and lymphatic system are all involved in cleansing and eliminating toxic by-products from the body. That being said, we are exposed to many toxins every day and we should be mindful of this and minimize the burden on our bodies when we can. Our bodies cannot effectively metabolize and eliminate all the toxins we are exposed to in the environment.
What about bleaching in tampons—does that pose a risk?
Tampon manufacturers and the FDA say that tampons are safe, and that the level of dioxins—a very dangerous chemical, and a by-product of bleaching—are so low that they pose no health risk. At one time, chlorine gas was used to purify the wood pulp which is used to make rayon. Tampons are made of rayon, in addition to cotton. This process did contribute to dioxins in tampons. Now wood pulp is purified using an elemental chlorine-free bleaching process that uses chlorine dioxide as the bleaching agent. This process can cause dioxins to be detected in trace amounts in tampons but the level is so low that it’s sometimes not even detectable. It is considered safe by FDA standards.
All that said, I do feel that tampon companies underestimate the effects of dioxin. And this is primarily because we’re not talking about a single tampon exposure. We are talking about thousands of tampons. Dioxin is one of the most dangerous chemicals on the planet. Even just a small amount can cause damage. So while the new bleach is definitely safer than other bleaches, we can’t assume that it is safe given the large amount of tampons women use over their lifetime. So while a single exposure, or even a handful of exposures may not be harmful, repeated exposure may be problematic—plus, dioxin can accumulate over time, so I prefer to avoid as much chemical exposure as possible.
And unfortunately, we’re not just talking about dioxin and glyphosate: We are exposed to chemicals and pesticides daily. They are in our food, water, clothing, cleaning supplies, cosmetics, water bottles, and even receipts. Some of these chemicals and pesticides can build up in the body. I know it can be overwhelming to think about. I hear people say, “What’s the point of making changes when you would need to live in bubble to truly protect yourself?” But I do think it can be empowering to know that there are simple choices we can make to limit our exposure. For example, buying organic tampons or choosing something entirely different to use during our periods can make a big difference.
Are there any other chemicals in tampons that we should be concerned about? Is it better to use something different entirely?
Generally tampons are made from cotton and rayon. Tampons are considered a “medical device” by the Food and Drug Administration and manufacturers are not required to issue a full disclosure of what is in their tampons. Tampons may have odor neutralizers, dyes, pesticides, and fragrances. If we are concerned about additives in our foods, we should be equally concerned about inserting them in our tampons—because the vaginal wall is so permeable, this allows toxins and chemicals like pesticides direct access to our bloodstream.
So what sort of menstrual products should we buy?
Again, this information should be empowering, as we know what to do to make better choices for our health. I wouldn’t worry about using a conventional tampon every once in a while when nothing else is available. But, when you have the opportunity, buy organic cotton tampons or pads. Santitary pads made with plastics have been shown to contain volatile organic compounds (VOCs). The best option here would be an organic, chlorine-free, non-applicator tampon or organic, chlorine free pad.
There are also a number of nontoxic and reusable (i.e., good for the planet) feminine hygiene products. Organic cloth pads are reusable and made from organic cotton, hemp, or bamboo. There are a number of different types of menstrual cups available, too. Menstrual cups are soft, flexible, and made from silicone. They are inserted into the vagina to catch menstrual flow and can be worn for up to 12 hours. Sea sponges are also free of additives and are reusable. It is definitely worth trying some of these methods—see which one works best for you.
