How Mushrooms Support Nervous System Regulation
Functional mushrooms have been used for centuries to support stress resilience, and modern science is now catching up.

Reishi is known as the “queen of mushrooms” for its calming effects. It helps regulate the HPA axis (your body’s stress-response system), supports parasympathetic tone, and promotes deeper, more restorative sleep.
Lion’s Mane supports brain health by stimulating NGF (nerve growth factor), which plays a key role in repairing and regenerating neurons—improving focus, memory, and emotional regulation.
Cordyceps helps regulate energy and adapt to stress by supporting mitochondrial function and balancing cortisol.
Adaptogenic synergy: These mushrooms work together to help your body respond to stress more intelligently—buffering spikes in cortisol, enhancing neuroplasticity, and calming the nervous system from the inside out.
Each mushroom in this stack is included at therapeutic levels, using fruiting body extracts only—no fillers, no mycelium on grain. Just pure, potent support.

From our Founder, Tonya:
This tincture stack was developed from my own healing journey.
For years, I lived in a constant state of overstimulation, burnt out, anxious, and reactive. On the outside, I was high-functioning. On the inside, my nervous system was running on empty. I didn’t know it at the time, but so many of my symptoms (including IBS) were rooted in dysregulation.
When I began working with functional mushrooms and adaptogens intentionally, everything started to shift. I stopped managing symptoms and started addressing the root. Nervous system support became the missing piece in my healing, a foundational tool for long-term resilience, digestion, and emotional balance.
I created this stack for anyone who's done with surface-level solutions. It’s a protocol for real, physiological support, grounded in science, designed for modern life. If you’re feeling stretched thin, stressed out, or stuck in a cycle of burnout and bloating, this is for you.
This is root cause care, in mushroom form.
