A Personal Journey
Meet Lauren and Matt, the wife and husband duo of Semaine.
Their personal journey led them to seek answers for Lauren's endometriosis and period cramps. With Matt's biology PhD, they developed the first PMS supplement you only take before and during your period, not all month long.

For Your Best Period Ever
Ingredients
ASHWAGANDHA
Discover Sensoril®, the patented vegan Ashwagandha extract crafted to lower cortisol (stress) levels, alleviate anxiety, boost mood, and aid in cramp relief by regulating inflammation.
BOSWELLIA
Introducing Casperome®, a patented Boswellia resin extract designed for enhanced absorption. Developed to alleviate inflammation, cramps, digestive discomfort, and headaches by targeting essential compounds known as prostaglandins.
CURCUMIN
Meet Meriva®. An advanced curcumin extract in a highly absorbable phytosome form, it supports a healthy inflammation response and is historically and clinically proven to enhance mood and soothe the intestines.
GREEN TEA CATECHINS
Experience Greenselect®, a green tea extract rich in catechins for powerful cell protection. Rigorously standardized for quality and caffeine-free, it boosts energy, and mental clarity, and supports overall well-being, particularly during menstruation.
MAGNESIUM
Our advanced magnesium formulation is crafted for optimal absorption. This essential electrolyte supports muscles, reduces inflammation for menstrual comfort, and helps regulate blood sugar while curbing cravings.
QUERCETIN
Quercetin is a powerful antioxidant, effectively neutralizing any harmful reactive molecules and enhancing your body's own defense mechanisms. It also combats inflammation and aids in maintaining balanced histamine levels, reducing the risk of headaches, and digestive issues.
RESVERATROL
We exclusively utilize the most extensively studied and highly bioactive form of resveratrol. This antioxidant, commonly found in red wine and dark chocolate, is expertly designed to neutralize free radicals associated with aging and chronic diseases, ultimately promoting cellular protection and overall well-being.
SILYMARIN
Introducing Siliphos®, a patented milk thistle extract enclosed in a unique sunflower lecithin-based phytosome. This encapsulation enhances absorption, supporting inflammation balance, stress reduction, liver function, and menstrual health.
VITAMIN D3
Our unique certified vegan Vitamin D3 is sourced from lichen, delivering all the benefits without the need for sheep wool extraction. Boost your immune system, combat stress, and potentially alleviate PMS symptoms with Vitamin D supplementation if you're deficient.

How to Take PMS & Period Support?
To have the best period ever, take 2 capsules up to 6 times per day, 2-3 days before your period begins.
Continue taking 2 capsules up to 6 times per day to help with mood swings, cramps, or bloating during your period.

Can I take more than one supplement?
We designed all of our supplements to work effectively together. We are complex humans, so we need different supplements at different stages of life. However, it's always a good idea to check with your doctor if you are starting any new supplement and taking one or more medications. We have a white paper that you can share with your doctor that explains the formulation, dosage, and clinical trial results so that they can help you make an informed decision: White Papers
