Drink Better, Focus Better
Enhanced Focus
When concentration is key, fixate on a coffee crafted with focus-inducing superfoods. Lion’s mane mushroom extract plus organic instant coffee help clear brain fog in just a few sips for the best mental pick-me-up.
Balanced Energy
Thanks to the L-Theanine, you won’t be going up and down on a caffeine rollercoaster when you drink your coffee or tea. Instead, you’ll feel stable and consistent energy.
Positive Mood
There are few areas of clinical research more active than the gut-brain connection. Functional mushrooms play a critical role in a healthy gut. They are rich in prebiotic fiber that feeds probiotics and supports a diverse, thriving microbiome. The gut microbiome produces key neurotransmitters like serotonin, dopamine, and GABA, which help regulate mood. A happy gut equals a happy mood.
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.
