How it works

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.

Start Semaine when you feel cramps, and continue for one week.

That's it. Powerful, hormone-free and drug-free relief when you need it.

Lessens cramps, reduces bloating and headaches naturally.

Increases energy and boosts mood

Energy-boosting without the caffeine while also lowering stress levels.

We tested Semaine on ourselves for 18 months as our third cofounder Matt used his science background (and Ph.D) to formulate the most effective solution to our pain.
