How much blood does your period underwear absorb?

Our Period Underwear absorbs about 25 mL (roughly the amount held by 3-4 regular tampons) of menstrual fluid. However, absorption is affected by many things, including your menstrual flow, position (sitting, standing, moving) and activity.

We recommend you use Period Underwear in the way that works best for you, which might require some trial and error. Some women prefer to wear period underwear as a back-up to other period care products, like pads, tampons, liners, or cup.
