In our open-label trial, 91% of people felt better their first period they took PMS & Period Support, and most users report that their periods get better with additional cycles. Clinical trial participants reported reduced bloating, milder cramps, fewer headaches and increased energy and better workouts during their first period using PMS & Period Support. 

We ask that you take your PMS & Period Support capsules for at least 2 months to determine whether they are effective for you. Our periods change from cycle to cycle, and stress from previous periods have been shown to impact how you feel now. Because of this, it can take a couple cycles for your body to full respond to the support that you are giving it now.
