Delicious, effortless, and no new habits required.

Why People Are Switching.
99% of our customer reviews are 4 or 5 stars.
Most mushroom coffee asks you to pick a side: something that tastes drinkable, or something dosed high enough to matter. We refused to make that trade. Craft coffee flavor AND 5,000mg of dual-extracted fruiting body mushrooms.

The flavor is amazing, but the best part is that the benefits of these mushrooms is absolutely real. My expectations were blown out the
door!
Tastes Great! I feel much calmer and more
focused.
Still curious? 🍄
Will I taste the mushrooms in the coffee?
Nope, not at all! While the mushroom concentrates themselves can be earthy and bitter, we take pride in the fact that our products are meticulously formulated to address this; resulting in super smooth, flavorful beverages that consistently receive praise for great taste. No muddy flavor here.
What are functional mushrooms?
All mushrooms serve a function, either as nourishment or as part of the ecosystem. Functional mushrooms are mushrooms with specific benefits to health. Functional mushrooms have studied benefits in the body. Most of these mushrooms work best as part of your daily routine. They contain beneficial polysaccharides, known as beta-glucans, and many contain beneficial triterpenes as well. Each functional mushroom has a slightly different set of actions in the body. In addition, they are antioxidants, adaptogens, and balance the body and the immune system.
Can I ingest too many mushrooms?
Mushrooms are food and have been consumed as both food and as medicine for many millennia. That being said, mushrooms are extremely safe in very high amounts, even in amounts 10 times higher than what is found in one of our servings!
Will this make me “trip”?
Sometimes people ask us if our mushrooms are the psychedelic (or magic) kind. They're not! But we think they're pretty magical nonetheless. Medicinal mush- rooms (sometimes called functional or adaptogenic) support overall wellness including brain function, immunity, and emotional calm and well-being. Each medicinal mushroom has a different positive effect. Most are potent antioxidants and create homeostasis, or balance, in our body, mind and immune system. Yay!
Why 5,000mg?
Most mushroom coffees land between 500 and 2,000mg per serving. We formulate at 5,000mg because that is the level our team believes is worth putting in a daily cup.
What is dual extraction?
Water pulls out the beta-glucans, alcohol pulls out the compounds water cannot reach. Doing both captures a broader
spectrum than either alone.
