So, one single supplement probably won’t capture and alleviate every single symptom, Tolentino says. Instead, you’ll have to asses which supplement or supplements you may want to try—but first, you have to take note of what you’re experiencing in the first place.

“Checking in with yourself, like monitoring the type and frequency of your PMS symptoms, documenting any noticeable patterns—these clues can be so helpful to your healthcare team to formulate a thorough plan to address your ongoing PMS,” Tolentino says. 

So if your cramps are really bad one day and gone the next, write that down. If you feel more anxious than usual, write that down. If you can’t fall asleep for hours for no other reason, write that down. Then, you’ll have an easier time picking out which ingredients and supplements may be helpful for your unique PMS experience.
