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.)

What on Earth is a Four Sigmatic food?

It’s simple (and slightly nerdy). They’re the 100 most-studied, most nutrient-dense foods on the planet. Here’s a graph.

Science time: when you plot out nutrition, each “sigma” equals how far a food is from the average. Four Sigmatic foods are much, much, much, much better. You might even say they’re the best.

Chaga Drink


Magic has never tasted this good

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 humor.)

Founder of Four Sigmatic - Tero


Our founder is a Funguy (sorry)

This is Tero. He grew up in Finland on a family farm that’s been around for 13 generations. There he learned to appreciate the best off-the-beaten-track ingredients and the absolute worst puns. Tero started Four Sigmatic to share these feel-good Finnish traditions with the world.

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. In which case, stop by our FAQs.

We don’t do things by the book (in fact, we wrote our own)

We have a sauna in our office. We also have a bus named Mauri (the Mushroom Mobile) and Maisa, the electric Mushroom Moped (Mauri’s sister). They travel around the U.S. serving up elevated essentials on wheels. This stuff just makes sense to us—and it makes people feel really good. We believe in it so much, we wrote an actual book full of health-supporting, functional-ingredient recipes.
