Lauren and Matt are the husband-and-wife duo of Semaine. Their journey led them to seek answers for Lauren’s endometriosis and period pain. Utilizing Matt’s biology PhD, they developed the first clinically studied PMS supplement for rapid relief. Now, Semaine is on a mission to inspire a future where women’s health and hormones are celebrated and understood.

How We Started

Plagued by extreme period pain ending in a confirmed diagnosis of endometriosis and emergency surgery, sisters Lar & Cath know a thing or two about menstrual discomfort. Lar regularly turned to NSAIDS and codeine just to make it through a workday. After extended NSAID use, she needed something different, so Matt set out to create a solution gentle enough for her stomach but powerful enough to zap her period pain.

And so Semaine was born. What started as a solution for painful periods has become a holistic approach to women’s health. Embracing customer feedback has given us the opportunity to provide better solutions and evolve with them. We’re here for every phase of your life.
