If you found this page you are likely interested in learning more about menstrual cups. The internet is a great place to do so!
Unfortunately the internet is also a great place for misinformation to take hold and spread.
Having worked in the menstrual cup industry for a long time I feel like I can shed some light on the most common misconceptions.
I will try to do so in a way that will let you apply that knowledge to whatever brand of cup you are considering.

A lot of things that excite me can be quite boring on first glance: material science, FDA regulations, etc. but I believe understanding them better will help you evaluate statements and advertising you see online.

Take what is useful and skip over the rest, if you like! I am glad you came. Let me know, if you have any questions or new topic ideas!
