De-Stress Your Cup
Stress Relief
Stress is part of life, but there are things we can do and add to our routine that help manage it so it doesn’t impact our brain and body functioning. Adaptogens, like reishi and tulsi, help you adapt to those everyday stressors.
Sense of Calm
Reishi mushroom has been used for 5,000+years for its plethora of benefits, namely its ability to help calm and relax the nervous system. Without being sedative, it gently moves our nervous system from sympathetic (fight or flight) into parasympathetic (rest and digest), supporting homeostasis and equilibrium of mind, body and spirit.
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.

A.K.A. Queen of mushrooms. But don’t worry, no royal status needed to enjoy the benefits of this stress-supporting super mushroom. (Royalty doesn’t believe in filler grains).
Calm
This Ayurvedic herb is a celebrity in the adaptogen world–and for good reason. It’s been used for generations to support so many conditions we can’t fit them all here, but stress relief is one of our favorites.
Stress Relief
Chamomile and lavender are two calming herbs that make for a very relaxing ritual. Both carry a gentle nervine that helps with relaxation and aiding a sense of calm. We pre-extracted the chamomile so you can mix it straight in cold water.
