From the Finnish countryside to your kitchen

For 11 years, Four Sigmatic has been serving up mushroom and adaptogen packed blends to improve your life. But our roots go back even further, all the way to WWII in Nordic land rich with lakes, forests, and lots of mushrooms.

"We started as a hard-to-understand brand ‘on shrooms’ but now we're doubling down on our true calling of delivering you mental performance and wellbeing."

Foraging mushrooms has always been an Isokauppila family tradition. The day our grandparents decided to blend their favorite mushrooms into their daily brew, a better morning ritual was born.


Based on the 100 most-studied, most nutrient-dense foods on the planet, each “sigma” represents how far a food is from an average nutritional value. Four Sigmatic foods are beyond better. You might even say they’re the best.
