Four Sigmatic Think Coffee

Four Sigmatic Think Coffee was one of the pioneers of the mushroom coffee trend, and their Think dark roast coffee is a classic for a reason. It features organic coffee blended with lion’s mane to improve focus and memory and chaga to boost overall mood and well-being. With over 17,000 ratings, it’s also the top-selling mushroom coffee on Amazon.

As far as taste, you’ll hardly notice there’s anything other than your favorite type of coffee in there. At 150 mg of caffeine, you won’t be giving up your regular cup of joe in exchange for the beneficial adaptogen compounds. While Four Sigmatic’s website says you’ll see improved focus in as little as seven days, I can attest that I felt the effects on the very first day.

Speaking of adaptogens, chill out with our favorite nonalcoholic canned cocktails.


  • Most similar to regular coffee (150 mg caffeine)
  • Contains 500 mg of log-grown lion’s mane and wildcrafted chaga for improved memory, focus and immunity
  • Utilizes fruiting bodies of mushrooms, not mycelium (roots)
  • Tastes like regular, dark roast coffee
  • USDA Organic


  • The serving (4 Tbsp per 12 fl oz) may be a little strong for some, but easy to adjust based on personal preference
