Now
FEM. reinvests 10% of its profits every year into the research women's health still needs.
Our story
Why we started FEM.
We started FEM. because we kept hearing the same story: women whose symptoms were dismissed, who waited years for answers, or who were told it was 'just hormones'. Part of the problem is that women's bodies have been studied far less than men's. We can't fix that alone, but we can help. So alongside making snacks fortified for women, we reinvest 10% of our profits every year into women's health research, so more can be understood and more women get the answers they deserve.
How it works
10% of profits. Every year.
-
You buy a box
