When in my cycle should I start taking Semaine Health PMS & Period Support?

To get the most of all the supportive goodness in PMS & Period Support, you should start taking it 1-2 days before you start bleeding or as soon as your PMS symptoms start.

If you are using birth control pills, start PMS & Period Support when you switch over to the placebo pills. Or if you use something like the NuvaRing, start Semaine when you take the ring out.
