Drink Better, Focus Better
Smooth Digestion
Your digestive system is like a second brain, with 100 million nerve cells linking your brain and gut. So when our digestion runs smoothly, so do our thought processes. Healthy gut, healthy mind.
Immune Support
In addition to helping with your gut microbiome, turkey tail mushroom extract is loaded with prebiotic fiber that helps feed the probiotics (good bacteria) in your gut. And ~70% of our immune system is located in our gut, so a healthy microbiome equals a strong immune system.
Probiotics
Each cup is packed with 1 billion CFU of heat-resistant probiotics, along with gut-nourishing prebiotics derived from yacon.
No Toxic Tea Bags
Say goodbye to microplastics and chemicals – our instant teas come in a convenient tea powder, free from toxins, fillers, and artificial ingredients.

Science-Backed Ingredients
This mighty wood-grown mushroom has prebiotics and research to support smooth digestion, one sip at a time. We extract our turkey tail from log-grown fruiting bodies: fully organic, with no fillers, grains or carriers.
Immune Support
The only probiotic we trust in our coffee because these 1 billion CFU of Bacillus subtilis (DE111®) will survive 5 minutes in boiling water, dissolves easily in water and are heavily researched.
Gut Health
This powerful Peruvian tuber is prebiotic-rich and supports a healthy microbiome so your gut can do its thing.
Prebiotic Fiber
Aside from its great flavor, organic ground ginger powder has extensive traditional use to support digestion so you can skip the mid-day bloat.
