Are Tampons Toxic? What You Should Know
By SELENACARE Redaktion · 27 February 2025
Tampons are one of the most popular menstrual products – but are they really harmless? A recent study showed that tampons contain traces of metals. That raises questions: do tampons contain toxins? Are they harmful to your health? And what alternatives are there? In this article you'll find out everything you need to know.
Do tampons contain toxins?
Whether tampons are toxic is a question that keeps being discussed. Critics point out that many conventional tampons are made of bleached cotton and viscose. In the past, the bleaching agent dioxin in particular caused a stir, as it could potentially be harmful to health.
However, German health authorities give the all-clear: the residue amounts used today are so small that, according to the Federal Institute for Risk Assessment, they pose no health risk. Nevertheless, some studies have shown that tampons can also contain other potentially concerning substances.
Tampons and heavy metals – what does the science say?
A study by the University of California, Berkeley examined 30 tampons from 14 different manufacturers and found all 16 metals tested, including lead, arsenic and cadmium. Particularly interesting:
- Lead was detected in all tampons examined.
- Organic tampons contained higher amounts of arsenic, while non-organic products showed more lead.
- The concentrations of the metals varied depending on brand and origin.
Sounds worrying? The good news: according to experts, the amounts are so small that they probably pose no direct danger to health. An Öko-Test analysis found, for example, that a person would have to use around 180 tampons in a single day to absorb a critical amount of antimony.
What does that mean for you?
Everyone should choose the menstrual product they feel most comfortable with. If you have concerns, you can switch to certified organic tampons or sustainable alternatives.
Tampon alternatives: sustainable options for your period
If you'd rather not use tampons or are looking for a more environmentally friendly solution, you have many options today. Here are three proven alternatives.

Frequently asked questions about tampons
How long can you leave a tampon in?
A tampon should not be worn longer than 4–8 hours to minimise the risk of toxic shock syndrome (TSS).
How do I insert a tampon for the first time?
Relax, choose the right size and insert it gently, angled towards your lower back. A guide or a mirror can help.
Which is better, tampons or pads?
That depends on your personal preferences. Tampons are more discreet, while pads are easier to handle.
Where does the tampon go?
The tampon is inserted into the vagina. Correct placement ensures you can barely feel it.
Who invented the tampon?
The first modern tampon design was developed in 1931 by Dr. Earle Haas.
Do tampons contain heavy metals?
Yes, traces of metals such as lead or arsenic have been detected in tampons. However, according to studies, the amounts are so small that they pose no immediate health risk.
What does that mean for you?
Tampons are not fundamentally toxic, but they contain minimal amounts of metals. Science currently does not consider this a health risk. If you're unsure, you can switch to organic tampons or sustainable alternatives such as menstrual cups or period underwear. Whichever product you choose – what matters is that you feel comfortable. ❤️
