Coffee with Probiotics

COFFEE + PROBIOTICS

Gut-supporting Morning Coffee

Your gut affects more than just digestion, it’s also a key part of our immune response, skin, and mood. A well-balanced gut can go a long way to helping you feel pretty fantastic overall. That’s why this delicious coffee blend contains 1 billion CFU of the hardy heat-resistant probiotic Bacillus subtilis, plus prebiotics from yacon, and the gut supporting mushrooms Turkey Tail and Chaga.

It’s all about routine! Since most people drink coffee in the morning, adding prebiotics, probiotics, and functional mushrooms to coffee is an easy way to elevate that cup of joe. Now you can incorporate gut support into your lifestyle and there’s no change to your coffee’s taste. Win-win! 

Ingredients: Organic and Fair-Trade Coffee, Organic Chaga Mushroom, Organic Turkey Tail Mushroom, Organic Yacon Juice Powder, Probiotic Bacillus subtilis

PROTEIN + MUSHROOMS + ADAPTOGENS

Everything your body needs to replenish and nothing it doesn’t. Not just for muscles, it has full-body benefits that include immune system and overall wellness support.  

But ... why mushrooms, adaptogens and protein? Because protein is the perfect vehicle for the nutritional benefits of these incredible mushrooms and adaptogens. Add it to your favorite smoothie, mix it with fruits and vegetables or drink it straight up in your favorite shaker.

TASTE TESTED

What about the taste?

We know, we know. Mushrooms. Sounds ... delicious, right? Well, actually, most people who try it think it is. We can talk all day about how good it tastes, but we’d rather let you taste it for yourself. So, we offer a 100% money-back guarantee.

Some people don’t like wine, some people don’t like jazz, and some people don’t like mushroom coffee. And that’s okay. Different strokes for different folks (and so on and so on, and scoobie-doobie-doo on).

We don’t want to force our coffee on anyone. So, if our coffee’s not your cup of tea, so to speak, send it back (shipping’s on us!), and you’ll get a full refund. In other words, it costs you zero to try. Nothing. Nada. Zilch.

Founder of Four Sigmatic - Tero

MEET TERO

Our founder is a Funguy

Meet Tero. He grew up in Finland on a family farm that’s 13 generations old (and the 14th generation is growing up fast). There he learned to respect Mother Nature and started Four Sigmatic with a bunch of other Funguys. Now we’re in over 65 countries, bringing feel-good Nordic traditions to the world.

The World's 100 Top Foods

We grew up in nature, foraging Chaga in our backyards, and eating all kinds of mushrooms for their benefits. Apparently most of the world doesn’t use mushrooms (or their mobile phones) in this way. So we decided to spread the word.

Four Sigmatic foods are the 100 most nutrient dense, most studied foods on the planet. And now they’re easy to add to your daily routines. We’re making these foods as easy as possible to eat and use and talk about. Because the world is asking more of you. Of everyone. We’d all feel a lot better doing that work if we got off the hamster wheel of coffee jitters and hangovers and sugar highs.

We don’t take ourselves too seriously. But our products are no joke. We only use the most studied ingredients from the most trusted sources. We geek out about our formulas and purity levels from our 3rd party testers so you don’t have to think about the science. Unless you want to. In which case, stop by our FAQs.
