Behind the Brand

Semaine Health was founded by twin sisters Lauren and Catherine Lee in addition to Lauren’s husband, Matt Crane. From their teenage years, Lauren and Catherine both constantly suffered from severe period pains and were eventually diagnosed with endometriosis in their late 20s. Even after undergoing multiple surgeries to remove the endometriosis, they still experienced immense pain during their periods. Lauren and Catherine took ibuprofen with codeine to help alleviate the discomfort but quickly grew fed up with the terrible side effects. Having witnessed his wife’s struggles for over a decade, Matt — a researcher with a PhD in Biomedical Engineering — decided to take matters into his own hands. He spent hundreds of hours researching plant extracts that were clinically proven to reduce period-related inflammation, experimented with blends of various plant powders (including curcumin, green tea, resveratrol, and magnesium), and started adding them into Lauren’s morning smoothies. One year later, Lauren experienced her first pain-free period.

Knowing that they had something special, Lauren, Matt, and Catherine decided to quit their jobs and commit full-time to Semaine. They conducted an independent third-party clinical trial to prove their product’s efficacy, set up an Indiegogo campaign to fund their first production run, and officially launched the company in March of 2020. Starting with their solutions for PMS and period pain, the Semaine team is working to address the lack of research around and remedies for period-related conditions. At the same time, they are shedding light on the inequalities in healthcare for women and striving to ensure that women’s health is taken seriously.

Meet the Maker

What has been your most unforgettable moment (good or bad) while building your company? - +

We've had some really great moments over the years, but our favorite is the daily comments we get from our customers about how much our products have helped them. It's what motivates to keep innovating and figuring out ways to make our products even more accessible to as many people as possible.

What is your favorite thing to do in your free time? - +

We all love to read and are all currently reading What Fresh Hell is This by Heather Corinna. It's this incredible mix of humor and education about perimenopause and menopause - everyone should read it! We're also big fans of shopping at our local farmer's market on the weekends.

What is an essential part of your daily routine? - +

Taking our supplements, of course! Ha! But also some sort of exercise - even if it's just a walk around the neighborhood. Entrepreneurship is intense and it's so important to pry yourself away from your computer and move a bit every day.

What is your biggest pet peeve? - +

How often women's health symptoms get dismissed by the medical community and society as a whole.

What is one thing most people don’t know about you? - +

All three of us have lived in Scotland at some point in our lives. If it wasn't so dark in the winter, we'd all move back in a heartbeat!

What do you want to be remembered for? - +

Providing solutions and support for people who either feel like they've been dismissed or ashamed for what's going on with their bodies.
