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!

I've had a few cramps here and there, but overall Semaine has been a miracle
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
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!

love it!!

Semaine has helped make my periods shorter and the pain nonexistent. I struggle with irregular periods so I always take it the day my period starts and it still helps to prevent period pain. Definitely recommend!

My cycle experience has changed forever!!

I was skeptical at first because I tried so many different things to help relieve the pain and bloating. Every month, for years, I struggled to do simple daily activities. This is literally a miracle in a bottle. Thank you so much for changing my experience. I recommend this to everyone I know and I will always be a customer!!

IG Ad that didn’t backfire!

Over the past year I’ve tried a variety of products that claimed to tame, control, or get rid of PMS symptoms and menstrual cramps all together. All purchased via Instagram sponsored ads. Many of them either failed completely, or barely affected my body. Until Semaine! Before trying Semaine I would spend at least every other period in the ER, after 48-72 hours of vomiting, diarrhea, and extreme cramps. Dysmenorrhea has been my official diagnosis since 11 years old. Over the counter pain medicine and the various types of birth control never worked. Sometimes even made the problem worse.

Semaine is right in line with my holistic lifestyle choices. It’s vegan, all natural, and is fast acting! Everything I’ve been looking for in a health product. Since trying Semaine in September 2020. I haven’t vomited once on my period and my cramps are manageable enough to go to work. That’s HUGE! Taking my pain levels from a 10 to a 3! I have been recommending this product to every female I know, especially the women with painful periods. I even use them for my PMS migraines.

Worth it

My periods are unpredictable -- in terms of when I get them, how long they last, and how painful they are. There's always some pain, though; sometimes it's a little, sometimes it's a lot. So I wanted to experience two cycles on Semaine before leaving a review. I feel like it really did make a difference, in particular in relieving cramping. During this last round, especially, there were several times when I felt like I was right on the edge and about to drop off into serious cramps but never actually did. The cost of the pills is a little high, but I am going to keep using them. I appreciate the way Semaine brings down inflammation and cramping. I also appreciate the loyalty program and the way that can help reduce the cost. Thank you!

Game Changer

I've used Semaine thru two periods now and wow is it a game changer! My before periods involved lying on the sofa clutching the heating pad for dear life for two to three days straight, unable to move without extreme pain despite taking ungodly amounts of prescription pain medication. Taking 3-4 doses, or 6-8 Semaine pills a day has reduced my pain enough that I take about 75% less traditional pain medication and can actually go about normal life on day one. On day two I have to take it easier but can still function normally at work with dull background cramps that come and go. Day three pain is nonexistent. That's far more relief than any doctor has been able to offer, without all the negative side effects of standard meds. Also, I typically have nerve pain in my upper back from a car accident, and I've noticed that those issues go away while on Semaine. That's a huge bonus I'm super thrilled about!
