WHAT IT DOES
Lion's Mane mushroom has been studied for its role in stimulating Nerve Growth Factor (NGF) — the protein essential for the growth, maintenance, and survival of neurons. Research suggests regular supplementation may support memory formation, processing speed, and mental sharpness, particularly during periods of sustained cognitive demand.
Cordyceps Sinensis has a long history of use in traditional Chinese medicine for energy and vitality. Research indicates it may support ATP synthesis — the fundamental currency of cellular energy. The result: reduced mental fatigue and more sustained output across long cognitive tasks, without stimulants or crash.
Reishi is among the most widely-studied adaptogenic mushrooms for its immunomodulatory and stress-buffering properties. By supporting a balanced cortisol response, Reishi protects against the cognitive drain of chronic stress — helping you think clearly under pressure and recover faster when demands are highest.

VERIFIED REVIEWS
"I've tried a lot of brain supplements. Most are just caffeine in disguise. Claros is different — I notice a genuine lift in focus without any crash. Three weeks in and I'm looking forward to taking it each morning."
"Three months in and still going. The effect is subtle but real — I'm sharper in meetings and faster to connect ideas. It's become a non-negotiable part of my morning."
"I switched to Claros after reading about Lion's Mane research. The fruiting body sourcing and clean formula set it apart from everything else I'd tried. No filler. No shortcuts."
ORDER
Take 2 capsules once daily, preferably with a meal. Each bottle contains 60 capsules — a full 30-day supply at the recommended dose.
Yes. All three mushrooms in the Claros formula — Lion's Mane, Cordyceps Sinensis, and Reishi — are sourced as organic whole fruiting bodies, not mycelium. Fruiting body extracts contain substantially higher concentrations of active compounds (beta-glucans, hericenones, triterpenes) than mycelium-based alternatives.
Adaptogens work cumulatively rather than acutely. Most people notice a subtle but real improvement in focus and mental clarity within 2–4 weeks of consistent daily use. Full effects typically become more apparent after 6–8 weeks of continuous supplementation.
Claros Cognitive Formula contains only organic mushroom fruiting bodies and standard capsule excipients (Brown Rice Flour, Gelatin, Magnesium Stearate, Silicon Dioxide). If you are under a physician's care or taking medication, consult your healthcare professional before use. If pregnant or nursing, do not use without consulting a physician first.

THE PROTOCOL
The Claros formula doesn't work like a stimulant — there's no switch, no crash. It works like a substrate: feeding the biological processes that govern how clearly you think, how long you sustain effort, and how resilient your mind is under pressure.
Lion's Mane stimulates the production of Nerve Growth Factor — the protein that governs how your neurons grow, form new connections, and survive under cognitive stress.
Cordyceps operates at the mitochondrial layer, optimising how your cells produce ATP. More mitochondria, running more efficiently, means more sustained output without a crash.
Reishi works upstream — modulating the hypothalamic-pituitary-adrenal axis so that chronic stress hormones don't silently degrade everything else the formula is building.
Why they're combined: Lion's Mane needs cellular energy to do its work. Cordyceps provides that energy. Reishi ensures the stress hormones that would otherwise sabotage both are held in check. The three are not substitutes for each other — they operate on different biological systems, in sequence. The formula works as a system, not a collection of ingredients.
This week is cellular logistics. The ingredients are being absorbed and distributed — visible effects, if any, are subtle. But the upstream chemistry is already underway.
Cordyceps Sinensis contains cordycepin — a molecular analogue of adenosine that interacts directly with adenosine receptors on your cells. Adenosine is the molecule that accumulates over the day and progressively signals fatigue; it's the reason you feel mentally slower at 4pm than at 9am. Cordycepin competes with adenosine at those receptor sites, partially attenuating the fatigue signal — particularly the afternoon cognitive drop that most people accept as inevitable. What you may notice this week: a subtle but real difference in afternoon clarity. Not a stimulant effect — more like the fog lifting slightly later than usual. Some people notice it in week one. For most, it becomes consistent by weeks two and three.
In parallel, Reishi's beta-glucans — large polysaccharide molecules — are being processed by pattern recognition receptors in the gut-associated lymphoid tissue. This activates macrophages and natural killer cells in the innate immune system, and begins signalling an upregulation of anti-inflammatory cytokines including interleukin-10 (IL-10). The result is a shift in your baseline inflammatory state that won't be perceptible this week but compounds significantly over the following months.
Lion's Mane is sending its first signals. The hericenones in the whole fruiting body are crossing the blood-brain barrier and reaching astrocytes — the support cells of the nervous system — where they initiate NGF synthesis. But neurons respond on a different timescale from small molecules. The infrastructure is being prepared. The effects come in month one.
Cordyceps works at the level of mitochondria — the organelles responsible for converting oxygen and nutrients into ATP, the universal energy currency of cells. Its primary active compound, cordycepin (3'-deoxyadenosine), is a structural analogue of adenosine with two mechanisms of action at the cellular energy level: first, it competes with adenosine at A1 and A2A receptors, reducing the adenosine-mediated fatigue signal; second, it improves the efficiency of the mitochondrial electron transport chain, reducing the production of reactive oxygen species (ROS) during ATP synthesis.
Longer-term, Cordyceps upregulates PGC-1α — a transcriptional co-activator that drives mitochondrial biogenesis. More mitochondria means greater capacity to generate ATP. This structural expansion of cellular energy capacity, accumulated over 4–8 weeks, is what produces the lasting improvement in cognitive stamina. It's not a transient boost — it's a rebuilt energy infrastructure. The same reason trained athletes have more mitochondria than untrained ones: the body adapts structurally to sustained demand.
By the end of the first month, the biological changes are measurable — even if some remain below the threshold of conscious perception. Three distinct adaptation processes are now running in parallel.
Lion's Mane: NGF upregulation is now consistent. The hericenones present in whole fruiting body stimulate Schwann cells and astrocytes to secrete more NGF, which binds to TrkA receptors on neurons and triggers downstream signalling pathways that support myelination — the myelin sheath that wraps nerve fibres and governs transmission speed. Better myelin integrity means faster, more accurate neural signal conduction. The subjective experience: faster retrieval, improved word-finding, better working memory performance under cognitive load. This is also where research evidence is strongest. A 2009 double-blind, placebo-controlled trial (Mori et al.) found statistically significant improvements in cognitive function scores in participants supplementing with Lion's Mane after four weeks, with effects increasing through week 16.
Cordyceps: Mitochondrial biogenesis is underway via the PGC-1α pathway. Your cells are building new mitochondria — new organelles, encoded by nuclear DNA, assembled inside existing cells. The effect is most noticeable during sustained cognitive effort: the concentration plateau you'd normally hit at hour two or three of deep work arrives later, or becomes shallower when it does. This is not stimulant tolerance — it's genuine structural expansion of cellular energy capacity.
Reishi: The HPA (hypothalamic-pituitary-adrenal) axis has begun to adapt. This is the hormonal cascade that governs the stress response: under chronic activation, it keeps cortisol elevated beyond its useful alerting window. The triterpenes in Reishi — particularly ganoderic acids A and C — have been shown to inhibit cortisol synthesis at the 11β-hydroxylase level, helping cortisol return to baseline faster after stress exposure. The result: a more measured stress response, lower evening cortisol, and better sleep onset. Circulating IL-6 — one of the primary inflammatory cytokines associated with cognitive fatigue — has also measurably declined.
Lion's Mane contains two classes of bioactive compounds found nowhere else in nature: hericenones (in the fruiting body) and erinacines (in the mycelium). Because Claros uses whole fruiting body, the active compounds are hericenones — small, lipophilic molecules that dissolve in fat, cross the blood-brain barrier directly, and stimulate NGF synthesis in astrocytes and Schwann cells.
NGF (Nerve Growth Factor) is not a neurotransmitter — it's a growth protein. It binds to TrkA receptors on neurons and activates a cascade of intracellular signalling (including the Ras/MAPK and PI3K/Akt pathways) that promotes axonal elongation, dendritic branching, and myelination. The significance: most cognitive supplements work by modifying neurotransmitter levels — a transient effect that vanishes when you stop supplementing. Lion's Mane supports the structural maintenance and growth of the neurons themselves. The improvements are more durable, and they compound over time.
This is also why the fruiting body matters. Mycelium-based products — cheaper to produce, widely used in mass-market supplements — contain significantly lower concentrations of hericenones and higher starch content from grain substrate. The neuroplastic effect depends on hericenone density. Claros uses only certified organic whole fruiting body.
Month three is where the cumulative biology becomes undeniable. Each of the three pathways initiated in week one and built through month one has now reached a new physiological equilibrium — and each one is reinforcing the others.
Lion's Mane: Sustained NGF signalling over 12+ weeks has driven measurable neuroplastic change. New synaptic connections have formed. Existing neural circuits have been reinforced through repeated activation and myelin deposition. Memory consolidation — the process by which short-term experiences are encoded as long-term memories, primarily during slow-wave sleep — is more efficient because the neural architecture supporting it has been maintained and extended. Human trials at 16 weeks (Saitsu et al., 2019) show continued and increasing improvement in cognitive function scores, with no plateau observed — the effects accumulate for as long as supplementation continues. The mechanism is not saturation: as long as neurons are being stressed and repaired, NGF-stimulated maintenance is active.
Cordyceps: Mitochondrial biogenesis is complete. Your cellular energy infrastructure has been rebuilt at the enzymatic level. The reduction in reactive oxygen species (ROS) during ATP synthesis has lowered oxidative stress across tissues — including neurons, where oxidative damage is a primary driver of age-related cognitive decline. The practical result: cognitive endurance is no longer the limiting variable in extended periods of sustained focus. The energy is available. The bottleneck has moved.
Reishi: The HPA axis adaptation is fully established. Cortisol follows a healthy circadian pattern: elevated in the morning for alertness and motivation, declining through the day, genuinely low by evening. This regulation has improved sleep architecture measurably: more Stage 3 slow-wave sleep, better REM proportion, fewer micro-arousals. The downstream cognitive consequences of improved sleep architecture are among the most robust findings in neuroscience — 20–30% improvements in memory consolidation, faster processing speed, improved emotional regulation, more consistent executive function. Reishi's sleep benefit is not sedative: it doesn't induce sleep by depressing the central nervous system. It removes a chronic hormonal interference with sleep that most people carry without knowing it.
By month three, the three systems are running in concert. The energy substrate is available. The neural architecture has been maintained and extended. The stress response is calibrated. What you've built over 90 days is not a dependency — it is a higher baseline.
Reishi's active compounds divide into two classes with distinct mechanisms: beta-glucans (long-chain polysaccharides) and triterpenes (particularly ganoderic acids A, B, C, and D). Each class acts on a different biological system.
Beta-glucans are immunomodulatory. They bind to Dectin-1 receptors on macrophages and stimulate a balanced, non-inflammatory activation of the innate immune system. The result is not immune suppression or stimulation but calibration: the immune system responds more accurately to actual threats, and baseline inflammatory markers (CRP, IL-6) decline toward optimal ranges. Chronic low-grade inflammation is among the most consistent findings in studies of accelerated cognitive ageing — Reishi addresses it at the signalling level.
Ganoderic acids work on the HPA axis via a specific enzymatic mechanism: they inhibit 11β-hydroxylase, the enzyme in the adrenal cortex that catalyses the final step of cortisol synthesis. By partially reducing the synthesis rate, they help cortisol return to baseline more quickly after stress exposure — without eliminating the cortisol response entirely, which would impair alertness and motivation. The practical effect: less cortisol overhang into the evening, faster sleep onset, deeper sleep, and faster cognitive recovery after high-pressure periods.
