For each supplement, the Semaine team spends hundreds of hours poring over clinical trial data, working to understand the biological mechanisms of action, and deciding which plant extracts to use.

To ensure the highest quality materials are used, we partner only with suppliers with transparent supply chains. Our especially rigorous testing program tests raw materials multiple times they go into a capsule (to test for things like heavy metals, pesticides and gluten), and then everything is tested again once the capsules are made.
