WHY WE'RE LIKE THIS

Putting the fun (and the fungi) in functional foods

Ever heard of Chaga or Lion’s Mane? We’re from Finland, where slightly-secret ingredients like these have been helping people seize the day for centuries. We couldn’t contain our excitement—so we turned them into delicious daily favorites to share with the world. Now they’re as easy and enjoyable as saying “Chaga” out loud. (Try it.)
