You don’t need more stimulation. You need better energy

Feel the Shift

Your body doesn't need another stimulant.

It needs better input.

Flow Brew turns your daily routine into a nervous-system ritual. Supporting focus, calm, immunity and gut health with science-backed mushroom compounds.

A different kind of energy in 2 weeks

Backed by science. Found in mushrooms.

Beta-Glucans (Immunity & Gut Health)

  • What they do: Strengthen immune defence, support gut microbiota and help regulate inflammation - all of which influence energy, mood and resilience.
  • Found in: Reishi, Chaga, Lion’s Mane, Maitake.
  • Backed by: Over 300 clinical studies on immune modulation, gut health and prebiotic function.

Triterpenes (Stress & Hormonal Balance)

  • What they do: Adaptogenic compounds that help the body regulate stress, support cortisol balance and promote a calmer nervous system response.
  • Found in: Reishi, Chaga
  • Backed by: Studies show triterpenes help modulate the HPA axis and reduce stress-related physiological strain.


Ergothioneine & Antioxidants (Cellular Defence)

  • What they do: Protect mitochondria, reduce oxidative stress and support long-term cellular health. Key foundations for recovery, ageing well and sustained energy.
  • Found in: King Trumpet, Shiitake, Maitake
  • Backed by: Called the “longevity nutrient” ergothioneine plays a key role in cellular protection and antioxidant transport.


Neuroactives (Focus & Brain Health)

  • What they do: Support neurogenesis, memory, and mood by stimulating Nerve Growth Factor (NGF) and key brain signalling pathways
  • Found in: Lion’s Mane (hericenones & erinacines), Cordyceps (cordycepin), Rhodiola, L-Theanine
  • Backed by: Clinical research links these compounds to improved focus, mental clarity and reduced brain fog.

Beyond Mushrooms. The Science of Calm Energy.

Medicinal mushrooms have been used for centuries. What we now understand is why they work. The bioactive compounds found in mushrooms support the nervous system, brain, immune response and stress regulation, the foundations of real, sustainable energy.

This is not about stimulation. It’s about restoring balance, resilience and clarity at the biological level.

Designed to support regulation, not overload.

  • 100% fruiting-body extracts Only the part of the mushroom shown to contain the highest concentration of active compounds. No fillers. No mycelium on grain.
  • Dual extraction Used to unlock the full spectrum of compounds, including beta-glucans and triterpenes, so nothing important is left behind.
  • Independently tested for purity and potency Every batch is third-party verified for heavy metals, purity and bioactive profile.

Stronger foundations for long-term health

Supports immune function and gut health. Both closely linked to energy, mood and recovery.

Found in Reishi, Chaga, Lion’s Mane & Maitake.

A calmer response to everyday stress

Helps regulate the body’s stress response and cortisol rhythm, supporting emotional steadiness and nervous system balance.

Found in Reishi & Chaga mushrooms.

Clear focus without mental strain

Supports brain signalling, memory and cognitive clarity. Helping you stay present and mentally sharp without feeling wired.

Found in Lion’s Mane, Cordyceps, Rhodiola & L-Theanine.

Steady energy, built at the cellular level

Supports mitochondrial health and oxygen utilisation, helping the body produce energy more efficiently, without spikes or crashes.

Found in King Trumpet, Chaga & Shiitake mushrooms.

The evidence behind the blend.

Here are peer‑reviewed studies, clinical trials and real‑world user data that support our ingredients.

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.
