PMS & Period Support

Rated 4.7 out of 5
Based on 103 reviews

We've experienced decades of bad periods and were tired of outdated, conventional period products. So we created the natural supplement we've all been looking for. Semaine PMS & Period Support works with your natural cycle, so you only need to take it when you are experiencing PMS or on your period.

Modify, skip or cancel anytime

Capsules packed full of 9 natural ingredients that help you have your best period ever. Semaine was created by founders who struggled with painful periods their whole lives and wanted a natural solution.

  • 100% vegan and plant-based
  • Ph.D. formulated
  • Gluten free
  • No sweeteners
  • Soy free
  • Caffeine free

Your solution to a healthier, happier period.

  • Plant-based, clinically studied ingredients
  • Designed around your natural cycle
  • Helps support your body to decrease bloating and cramping*
  • More energy, and better workouts*
  • Just for when you are experiencing PMS or on your period
  • Healthy support for when you need it*

In our open-label trial, 91% of people felt better their first period they took Semaine. Participants reported reduced bloating, milder cramps, fewer headaches and increased energy and better workouts.

Start taking Semaine when your cramps and other PMS symptoms begin, or 1-2 days before you start to bleed. For most people, taking 2 pills in the morning and 2 in the evening works well, though we frequently take 2 capsules with every meal. Continue taking capsules until your period ends (Semaine is safe to take all cycle so if you have discomfort around other times like ovulation, you can Semaine then too!).

Always formulated without soy, hormones, or synthetic fillers, Semaine PMS & Period Support is full of just the good stuff:

  • Vitamin D3 (as vegan cholecalciferal from lichen) - 60 mcg (300% DV)
  • Magnesium (as Sucrosomial® Magnesium) - 45 mg (11% DV)
  • Ashwagandha (as Sensoril®) - 66 mg
  • Boswellia extract phytosome (as Casperome®) - 126mg
  • Curcumin phytosome (as Meriva®) - 324 mg
  • Green Tea phytosome (as GreenSelect® Phytosome) - 126 mg
  • Quercetin phytosome (as Quercefit®) - 141 mg
  • Resveratrol (as trans-resveratrol) - 123 mg

amazing!!!

I was not able to take semaine on the days leading up to my period because my period is unpredictable and although I use a period tracker I never really know when it is coming. the first day of my period the cramps were intense and I had to take 2 capsules 4 times that day. all the following days of my period though, I have just had to take two capsules in the morning and two at night and the cramps have been minimal to nonexistent. Also I like that the pills don't have a strong scent or aftertaste. I tried another brand that had a very strong aftertaste that I didn't mind but I prefer not to have to deal with. So happy I don't have to rely on ibuprofen anymore!!

also I am usually incredibly nauseous on my period and I noticed I had 0 nausea! also my flow has always been heavy and the flow has significantly decreased. I am shocked.

Loved it!

Helped kick cravings and stabilize my mood. Just my first week so I’ll definitely be trying again next month. Wish it was easier to take, as having to remember 2 pills 2x/day can be tricky, but I just put them out on my dresser so I remembered.

That's great news about the reduction in cravings and stabilizing your mood! And we totally understand that taking two pills two times a day can be tricky! We recommend you take that many because you'll get enough of the anti-inflammatory properties that are in the supplement. That being said, if your pain isn't bad, try taking two pills just once a day or one pill twice a day. Let us know how it goes!

I’m so amazed

I haven’t felt this good in 6 months. I can’t believe how effective this is & how little pain I’m feeling. I feel like myself again! Honestly, idk how I would be able to live or function w/o Semaine!
