Burnt Out? Your Nervous System is stuck...

Find your tincture

This isn’t a productivity problem. It’s nervous system dysregulation.

Our mushroom tinctures deliver concentrated, fast-absorbing compounds - directly into your system - to help your body find its way back to balance.

Real People. Real Shifts.

Why Mushrooms work when everything else hasn't...

Beta-Glucans (Immunity & Gut Health)

Beta-Glucans strengthen your immune system and support your gut, both directly linked to your energy, mood and ability to recover. Found in Reishi, Chaga and Lion’s Mane, and backed by over 300 clinical studies.

Triterpenes (Stress & Hormonal Balance)

Triterpenes help your body regulate its stress response, calming the HPA axis and supporting cortisol balance so your nervous system stops running on high alert. Found in Reishi and Chaga.

Ergothioneine & Antioxidants (Cellular Defence)

Ergothioneine protects your cells from the inside out, reducing oxidative stress and supporting the mitochondrial health that underlies real, lasting energy.

Neuroactives (Focus & Brain Health)

Neuroactives support brain signalling, memory and focus by stimulating Nerve Growth Factor. Clinical research links these compounds to clearer thinking, better mood and less brain fog. Found in Lion’s Mane and Cordyceps.

Beyond Mushrooms. Beyond Supplements

Most supplements ask you to trust the label. We ask you to trust the biology.
Tinctures absorb faster, dose more precisely, and deliver compounds in their most bioavailable form.

That’s why we moved to tinctures exclusively, because absorption is where most mushroom products fail, and we’re not willing to compromise on that.


But the tinctures are the foundation, not the whole picture. Pair them with the daily practices that support regulation, breath, movement, sleep, stillness and you build a new baseline over 90 days.

This is regulation, not stimulation.

Why Our Tinctures Actually Work...

Most mushroom products are weak, under-dosed or poorly absorbed.

Powders in particular struggle with bioavailability, the compounds exist, but your body can’t always access them.


We moved to tinctures because the science is clear = liquid extracts taken sublingually absorb faster and more completely than powders.

We made sure ours are the best available:


100% fruiting body extracts (not mycelium on grain). The actual mushroom, where the bioactive compounds live.

Dual extraction (hot water + alcohol). Unlocks beta-glucans AND triterpenes, most brands only extract one.

Independently tested for potency. Every batch verified. You get what the label says.

Sublingual delivery. Absorbed directly into the bloodstream, bypassing the digestive process that reduces the potency of powders and capsules.


If it doesn’t work at the biological level, we don’t sell it. That’s why we only create our own tinctures.

The Science That Actually Matters

We're not asking you to trust vague wellness claims. Here are peer-reviewed studies showing why these compounds work
for stress, focus, sleep and performance.

Lion’s Mane Cognitive Function in Adults

2009
In a 12-week placebo-controlled trial, daily Lion’s Mane supplementation was linked with improved scores on standard cognitive tests in older adults with mild memory problems. The authors concluded it may help maintain healthy brain function as we age.

Mushrooms, Mood & Sleep in Young Adults

2025
A recent double-blind study in healthy young adults tested a blend of Reishi, Cordyceps and Lion’s Mane. Participants taking the mushroom extract reported better sleep quality, improved mood and lower salivary cortisol compared with placebo, suggesting benefits for stress and recovery.


Cordyceps and Exercise Performance

2017
In a placebo-controlled trial, a Cordyceps-rich mushroom blend taken for three weeks improved markers like VO₂ max and time-to-exhaustion during high-intensity cycling. In simple terms: participants could push harder for longer after consistent Cordyceps use.


Reishi, Sleep and the Gut–Brain Axis

2021
Emerging research on Reishi (Ganoderma lucidum) shows it can influence the gut microbiome in ways that promote deeper, more restorative sleep in animal and early human studies. Together with reductions in stress and fatigue, this positions Reishi as a promising ally for nervous-system balance. 


Ready to fix your nervous system?

Add to water or directly under the tongue. 30 seconds. Done.

Commit for 90 days. Your nervous system will tell you the difference.

This is regulation, not stimulation. And it works.
