Reusable menstrual cups have been around for decades, but they are just starting to pick up in popularity. Most people can’t shake their familiar comfort with tampons and pads, but a new study indicates that the cup is just as effective as the disposables and has no health risks. If you can get past the learning curve and “ick” factor, the menstrual cup is one of the easiest and most sustainable options for your period. Reusable cups are typically made from silicone or rubber and are inserted into the vagina.
