About This Brand

Four Sigmatic

Four Sigmatic was created by a group of friends with a passion for medicinal mushrooms. They left their well-paid jobs with companies like Google, Citibank, and Hewlett-Packard to work on their “mushroom mission.” In 2012 their journey began in the Nordic country, which they consider home.

This is perhaps my favorite discovery in the past year. I do not drink caffeine, but the chaga elixir gives me a great boost in the morning, and the taste is pleasantly earthy. Delicious with coconut milk! Plus chaga is known to have many amazing health benefits - read up!

Mega immune boost & tasty

Posted   by Meridith from DALLAS, Texas
After over 2 years drinking this regularly, my immune system loves me for it! As they also add rosehips for vitamin C, you can't go wrong. As it is mushroom extract powder, maybe you need to blend it for the taste. I love it heated in 4oz hot water though. I find it tastes better not any more watered down.
