About Four Sigmatic

This stuff comes naturally to us

We started back in Finland, where saunas outnumber cars and people love coffee as much as they love nature. So much so that our grandparents brewed a coffee replacement out of mushrooms during WWII. (More on this later.) 

FUNCTIONAL MUSHROOMS AND MORE

Our Finnish grandparents brewed mushrooms when they couldn’t get coffee. Turns out those mushrooms—Chaga—are a powerful, immune-supporting Four Sigmatic food. That gave us an idea.

We searched for more exhaustively-studied, practically-magic Four Sigmatic ingredients to add to our daily go-tos. Guess what? Organic coffee plus Chaga is chaga-bly delicious and remarkably good at balancing caffeine. Goodbye, jitters and sugar highs! (And hello, somewhat regrettable sense of humour.)

RIGOROUSLY RESEARCHED AND LAB-TESTED

RELISH THE RESULTS OF OUR ROCKET SCIENCE

As you might have guessed, we don’t take ourselves too seriously. But our products are no joke. We source the world’s very best ingredients. We also work with 3rd party testers to geek out about formulas and purity levels, so you don’t have to think about the science. Unless you want to.
