What Semaine Users Are Saying

I'm in the middle of taking Semaine and I see a BIG difference in how I feel. Last month I was tortured by cramps, and this month is SO much better!

Kaitlyn, Atlanta GA

I've had a few cramps here and there, but overall Semaine has been a miracle and I'm going to order more right now so I'm ready for next month!

Lauren, Salem MO

I always want to take ibuprofen or Aleve but know they will never help, so I never do – but Semaine did!

Diane, NYC

I had energy all day – felt refreshed compared to feeling sluggish and irritable all day. Plus my cycle was shorter!

Christina, Atlanta GA

I don't dread starting my period again after my second pregnancy this summer because I know I'll be able to take Semaine to manage the pain and discomfort.

Lena, Detroit MI

The thing I've noticed most is my energy level. I've had so much energy for all my work and was literally dancing in my office!
