What's inside
Real coffee & mushrooms. Nothing else.
Real, organic, single-origin Arabica from a family-run co-op in Honduras, medium roasted. Then we add 1 billion CFU of heat-resistant probiotics, prebiotic yacon, and organic turkey tail and chaga extracts to every cup. No fillers, no proprietary blends that hide the dose.
The taste
It tastes like coffee because it is coffee.
“Well-balanced and highly drinkable. Subtle fruit complexity complements caramelized sweetness.”
Scored 95.5 out of 100 by a certified Q grader. The mushrooms, probiotics and yacon are extracted and flavorless, so there is zero mushroom taste in the cup.
Q grader cupping evaluation · SCA standards · July 2026
Our organic Arabica coffee beans come from a small family-run co-op in Honduras, medium roasted for a smooth, sweet cup with regular caffeine. The turkey tail, chaga and probiotics are extracted and flavorless, so it tastes like good coffee because it is.
One cup. Everything your morning needs.
Real medium-roast coffee that is kind to your stomach.
Real organic coffee + probiotics + turkey tail + chaga, all in one cup.
Real results from coffee drinkers who thought coffee hurt their stomach
The only coffee that doesn't upset their stomach.
I've bought this coffee for my family members who struggle with gut issues and it's the only coffee that doesn't upset their stomach. Love to know they're getting the benefits from mushrooms and probiotics without sacrificing flavor! I cannot recommend more.
Improved digestion.
I started with Gut and soon recognized improved digestion and elimination. I have used many probiotics and pre biotics over the years, some very expensive, and did not really deliver the results I noticed using Gut.
My Favorite Ground Coffee!
I love the flavor of Ground Mushroom Coffee with Probiotics. Not only is it delicious coffee, but I also know I'm getting a dose of mushrooms AND probiotics to support my health! It's the real deal.
