Calling all people who are using birth control, this may be the most important thing you hear today!
There's just so many things women using contraceptives have to be aware of. Now you're gonna go ahead and tell them their breakfast time is about to be ruined as well - good luck!
If you are a lover of grapefruit, well we hate to be the bearer of bad news but apparently, the citrusy goodness lowers the effectiveness of birth control methods. According to science (thanks science) grapefruit targets your estrogen, lowering levels of some scientific thing call CYP3A, which is responsible for metabolizing medications. The change in CYP3A impacts the way your body controls medicine into the bloodstream.
There are a whole lot of other scientific things that we would totally be faking that we knew so instead, just take this as your PSA, be wary of grapefruit and your contraceptive methods!
