Focus and memory have genuinely improved since starting this. I work in a demanding role and the difference in sustained concentration through long days is noticeable. Three months in and it keeps getting better.

The Experience
What You'll Feel
Week 1
Beta-Glucan Priming
Polysaccharide compounds from Reishi, Turkey Tail, and Shiitake begin interacting with gut-associated lymphoid tissue. The immune-priming process starts with the first dose — GALT receptors respond to beta-glucans within hours.
Week 2
Microbiome Response
Mushroom prebiotic fibres begin selectively feeding beneficial bacterial populations. Gut-immune communication improves as the microbiome responds to the polysaccharide compounds across all 10 species. Some notice reduced bloating or improved digestion.
Week 3
Immune Activation
NK cell activity begins to elevate meaningfully as Reishi and Turkey Tail beta-glucan accumulation continues. Upper respiratory defences strengthen. The immune-modulating effect is building in both speed and depth.
Week 4
Cognitive Sharpening
Lion's Mane NGF synthesis is now meaningfully elevated. Subtle but noticeable improvements in mental clarity, focus, and recall begin to emerge — particularly during cognitively demanding tasks or high mental-load periods.
Week 6
Energy Building
Cordyceps ATP production benefits are fully established. Physical endurance during exercise improves and daily energy becomes more consistent — a steadier, cleaner output without caffeine dependence or stimulant rebound.
Week 8
Full Stack Active
All 10 mushroom species are simultaneously active and synergistic. Cognitive clarity, immune resilience, sustained energy, and cellular antioxidant protection are all meaningfully elevated above pre-supplementation baselines.
Week 12+
Peak Performance
The full compound effect is established. NK cell activity, NGF synthesis, mitochondrial energy output, and Chaga antioxidant protection all continue to compound with daily use. Cognitive, immune, and energy benefits are now your daily standard.
The Formula
Why Our Mushroom+
Most functional mushroom supplements contain one or two species at low doses — enough to carry an ingredient claim on the label, not enough to produce meaningful benefits. Our formula combines 10 species in a single 2-capsule serving: four at full individual doses (266mg each: Cordyceps, Reishi, Shiitake, Lion's Mane) plus a concentrated proprietary blend of six further species including Chaga, Turkey Tail, and Maitake. Fruit body extracts are used throughout — ensuring the active beta-glucans and polysaccharides are fully concentrated and bioavailable, without the indigestible chitin content of raw mycelium powders that limits absorption in most competing products.
The Science
Evidence-Based Formulation
Every species in Mushroom+ is selected based on peer-reviewed clinical research — fruit body extracts at evidence-backed doses, covering cognitive support, immune modulation, energy metabolism, and antioxidant defence.
01
Hericium erinaceus (Lion's Mane) Significantly Improves Mild Cognitive Impairment — Double-Blind Placebo-Controlled Trial
A randomised, double-blind, placebo-controlled trial found Lion's Mane (Hericium erinaceus) significantly improved cognitive function test scores over 16 weeks through stimulation of Nerve Growth Factor synthesis — one of very few natural compounds capable of promoting neurogenesis and myelin repair in adult brain tissue.

Reishi mushroom enhances natural killer cell activity and modulates the immune response
Reishi (Ganoderma lucidum) contains beta-glucans and triterpenes that directly enhance natural killer cell cytotoxicity and macrophage activity. Clinical studies show significant improvements in immune cell counts after 4–8 weeks, alongside modulation of inflammatory cytokines supporting both immune activation and recovery.

Cordyceps improves VO2 max and exercise performance via enhanced ATP synthesis
A double-blind trial found Cordyceps sinensis significantly improved VO2 max and time to exhaustion versus placebo. The mechanism involves enhanced ATP synthesis via adenosine precursors supporting mitochondrial energy production, with statistically significant aerobic capacity improvements over the 12-week trial.

Chaga mushroom provides exceptional antioxidant protection and beta-glucan immune support
Chaga has one of the highest recorded antioxidant values of any natural compound, driven by melanin pigments and superoxide dismutase activity. Research shows significant reductions in oxidative stress markers and activation of innate immune pathways via beta-glucan polysaccharides.

Turkey Tail's PSK compound is the most clinically studied mushroom immune extract in the world
Turkey Tail contains PSK (Polysaccharide-K) — an immune compound with over 30 years of clinical research. PSK activates T-lymphocytes, natural killer cells, and macrophages simultaneously. The mushroom also provides prebiotic fibres that support gut microbiome diversity and the secondary immune response.

Shiitake's lentinan compound supports immune function and reduces LDL cholesterol
Shiitake (Lentinus edodes) contains lentinan — a beta-1,3/1,6-glucan with well-documented immune-stimulating activity. Clinical studies show regular Shiitake consumption significantly improves immune cell proliferation and reduces LDL cholesterol and oxidation, activating macrophages and enhancing natural cellular defence.

How to Take It
01
2 Capsules Daily
Take 2 capsules daily with a meal. Morning with breakfast is ideal for cognitive and energy support — the Cordyceps and Lion's Mane compounds are most effective when taken at the start of your day.
02
Consistency is Everything
Functional mushrooms work through accumulation. The beta-glucan and NGF benefits build over 4–8 weeks of daily use — not hours. Taking it sporadically won't produce meaningful results.
03
Allow 4–8 Weeks
Most people notice the immune and energy effects first (weeks 2–3), followed by cognitive improvements from Lion's Mane as NGF synthesis builds (weeks 4–6). Give it the full 8 weeks before judging the effect.

Used to pick up every cold going around the office. Two full winter months on Mushroom Plus and I haven't been sick once. That's genuinely unusual for me and the Turkey Tail immune support is clearly working.
Cleaner, more consistent energy without the afternoon caffeine crash. I stopped relying on a second coffee after starting this — didn't expect that benefit from a mushroom supplement but I'll take it.
Good product. The cognitive benefits from Lion's Mane take a few weeks to build rather than arriving quickly. Once they did, the improvement to focus and mental stamina was real and consistent.
I run regularly and the Cordyceps effect on endurance is real. VO2 max has improved and recovery between sessions is faster. Didn't expect a mushroom supplement to move the needle on athletic performance.
Sleep quality has improved alongside everything else — I think that's the Reishi. Ten species at meaningful doses in one capsule is exactly the comprehensive approach this category needs.
Ten mushroom species including Lion's Mane, Reishi, Chaga, Cordyceps, and Turkey Tail at proper doses. Hard to find this breadth and quality in one product at this price point.
Four months of consistent daily use and it's become a non-negotiable. The cognitive, immune, and energy benefits compound over time. A staple supplement I have no plans to drop.
