"This is the best-tasting mushroom coffee that we’ve reviewed — it’s sweet without being syrupy, with just a touch of nuttiness and earthiness."
What makes Four Sigmatic unique?
We’ve spent over a decade perfecting our craft as pioneers in the functional coffee industry. Unlike coffee alternatives, we use real, organic coffee, enhanced with the benefits of healing mushrooms and adaptogens. Our coffee delivers clear, calm, and focused energy, all while addressing common coffee complaints-- It’s everything you enjoy about coffee, made even better.
When should I expect to see benefits?
Right away you should feel focused and more productive. After a few weeks you’ll start to notice that you are less likely to feel run down, or foggy. Functional mushrooms are safe to consume long-term and you’ll notice how much better you feel now if you try a cup of regular coffee after a month of your Think Ground Coffee.
Are these magic mushrooms?
Some might call the way they make you feel magic, but rest assured, these mushrooms are not psychedelic!
How much caffeine?
Each serving contains 90 mg of caffeine—giving you smooth, sustained energy with the same caffeine as a regular cup of coffee.
