The Only Clinically Tested PMS Supplement
Semaine is the natural solution for PMS and period relief.
As part of our cycle, inflammation increases when we are menstruating. This causes cramping, bloating and PMS.
Semaine was designed with 9 powerhouse plant extracts and minerals to help your body when you need it the most, and we've conducted a clinical trial to show this.


"There have been many days where I laid in bed and prayed to die so the pain would stop on my cycle. I tried these for the first time this month and I feel alive."

"I’ve tried literally EVERYTHING when it comes to my period. I finally found these and they are a GAME CHANGER!"

"I can’t believe how much Semaine has helped me already!! Usually on my first day bleeding I can’t get out of bed and have to just lie on my heating pad, but today I’ve worked with no pain."
