You might have heard some confusing things about tampons and lead. Let's clear things up with a quick look at common myths and the real facts!

Fact: Just because we can find something doesn't mean it's harmful!
Our super sensitive tools can detect tiny amounts of substances everywhere – we call these trace elements. What truly matters for safety, is ‘Exposure’ (or in the case of heavy metals, how much gets into your body).
Fact: Not true!
Your menstrual fluid (your period) has special helpers that grab onto or bind tiny substances, like lead. This "binding" means most of the lead gets stuck, is absorbed into the tampon, and isn't available to be absorbed by your body. It gets carried away when you remove the tampon.
Fact: Did you know that tiny amounts of lead can be found throughout the environment and in our bodies?
In fact, trace amounts can even be present in menstrual blood. During your period, your body sheds blood and tissue that may contain these naturally occurring trace amounts of lead. The amount of lead that can be present in menstrual blood is often greater than the microscopic amounts that have been detected in some tampons. Even when present in a tampon, very little, if any, absorbs into your body.
Fact: Only a very, very small amount of lead, if any, actually leaves the tampon.
To picture how small that is, one nanogram is like a single drop of water in an Olympic-sized swimming pool—making any potential exposure negligible. Most of it stays trapped within the tampon and is thrown away when you're done.
Fact: New research has looked closely at lead in tampons!
Scientists now have a much better understanding of how your period fluid interacts with these elements, giving us a clearer picture of what truly happens with lead during tampon use.
Fact: This research reaffirms that tampons are safe when used as intended!
It adds to what we already know and shows that any trace elements are at levels that simply don't affect your health.
Fact: To truly understand safety, you have to look at the whole picture!
To understand whether chemicals are actually dangerous, scientists look at factors like how much is released, how it interacts with your body, and how it behaves once it’s in your body. This research shows that there is very little potential exposure, making the overall risk extremely low.
