Lion’s Mane in 60 seconds
- Hericium erinaceus, in Polish soplówka jeżowata, Japanese yamabushitake (mushroom of mountain monks), Chinese hou tou gu (猴頭菇, „monkey’s head"). The English „Lion’s Mane" refers to the white, cascading fruiting body resembling a lion’s mane.
- Bioactive compounds: hericenones A-K (mainly the fruiting body), erinacines A-K (mainly the mycelium; erinacine A crosses the blood-brain barrier), β-1,3/1,6-glucans above 30%, ergosterol, ergothioneine.
- Mechanisms described in the literature: hericenones stimulate NGF synthesis in glial cells (in vitro); erinacines raise hippocampal NGF in animal models; β-glucans activate Dectin-1 and TLR4 and modulate the gut-brain microbiota.
- Strongest clinical studies: a 16-week RCT (Mori 2009, n=30 with MCI, 3 g/day); a 4-week RCT (Nagano 2010, n=30 women, 1.5 g/day); a 28-day RCT (Docherty 2023, n=41 young adults, 1.8 g).
- In TCM it tonifies the Qi of the Stomach and Spleen and calms Shen (the mind). Sweet and bland taste, neutral nature. Meridians: Stomach, Spleen, Lung, Heart.
- Our raw material: a 10:1 H. erinaceus fruiting-body extract, standardised to above 30% β-glucans (EUROFINS lab), no maltodextrin, tested for heavy metals and pesticides.
What lion’s mane is and where it comes from
Soplówka jeżowata is the common Polish name for the mushroom Hericium erinaceus of the Hericiaceae family. In English Lion’s Mane (from the fruiting body’s resemblance to a lion’s mane), in Japanese yamabushitake (山伏茸, „mushroom of the yamabushi monks"), in Chinese hou tou gu (猴頭菇, „monkey’s head"). In Poland the species is strictly protected in the wild, so every extract on the market comes from controlled cultivation, not from forest foraging.
The mushroom grows on the trunks of deciduous trees, mainly beech, oak and walnut, in forests of the northern hemisphere. The fruiting body is white and fluffy, with downward-hanging narrow spines 1-5 cm long, resembling a cascade of icicles. In controlled cultivation it is grown on oak or beech sawdust enriched with bran, which gives a repeatable hericenone content and full control of contaminants.
Tradition of use
In Japan lion’s mane was used by the yamabushi monks, ascetic mountain practitioners of Shugendō, as a tonic supporting long meditation sessions and clarity of mind. The name yamabushitake comes from this tradition. In China, under the name hou tou gu, the mushroom was an ingredient of classical herbal formulas for „weakness of the Qi of the Stomach and Spleen", today interpreted as support for digestion and general weakness.
Modern science on Lion’s Mane began with two Japanese discoveries in the 1990s. In 1991 the team of Hirokazu Kawagishi at Shizuoka University isolated from the fruiting bodies a group of compounds that stimulated NGF production in glial cell cultures. He named them hericenones. In 1994 the same team identified a second class, the erinacines, present mainly in the mycelium. These two discoveries set off a wave of research, today exceeding 1500 peer-reviewed publications.
Bioactive composition, what is in the extract
Lion’s Mane is the only functional mushroom in which two key classes of bioactive compounds are split between the fruiting body and the mycelium, rather than accumulating in one part. This matters for understanding the extract market:
Hericenones A-K, aromatic compounds present mainly in the fruiting body. Four of them (C, D, E and H) most strongly stimulate NGF synthesis in astrocyte cells in vitro.
Erinacines A-K, diterpenoids present mainly in the mycelium and in small amounts in the fruiting body. Erinacine A is one of the few fungal compounds that crosses the blood-brain barrier in an animal model and raises hippocampal NGF.
β-1,3/1,6-glucans, polysaccharides activating Dectin-1 and TLR4 on dendritic cells. Standardised in our extract to above 30%. In addition ergosterol and provitamin D₂, ergothioneine (a natural antioxidant) and trace elements.
This is why a fruiting-body extract and mycelium on grain are two different products. The fruiting body delivers hericenones and a fuller β-glucan profile. Mycelium on grain contains erinacines only partly and is 70-85% grain substrate, which dilutes the profile. Aloha Fungi works only with the fruiting body.
How lion’s mane works: three mechanisms
Mechanism 1. Hericenones and NGF synthesis in glial cells
The best-described mechanism in the literature and historically the first. Hericenones, especially variants C, D, E and H, stimulate NGF (Nerve Growth Factor) synthesis in glial cell cultures (astrocytes) in a dose-dependent way. NGF is a protein essential for the differentiation, maturation and survival of cholinergic neurons.
The mechanism has an important limitation: hericenones cross the blood-brain barrier poorly after oral intake. Most of the effect must act indirectly, through modulation of the peripheral nervous system or through cells in the gut wall (the gut-brain axis).
Mechanism 2. Erinacines, BDNF and crossing the blood-brain barrier
Discovered a few years after the hericenones and potentially more clinically important. Erinacines are small-molecule diterpenoids which, unlike hericenones, cross the BBB in an animal model. In Lai 2013 (rats) oral supplementation raised hippocampal NGF after 7 days. Erinacine A also showed an effect on BDNF (Brain-Derived Neurotrophic Factor) in an animal model.
Erinacines occur mainly in the mycelium and in smaller amounts in the fruiting body. A well-executed fractional extraction of the fruiting body contains enough erinacines, whereas a fruiting body + mycelium-on-grain combination often simply means dilution with starch.
Mechanism 3. β-glucans, the gut-brain axis and microbiota modulation
The newest in the literature and the fastest-growing research direction. β-1,3/1,6-glucans activate Dectin-1 and TLR4 on dendritic cells of the gut wall. This triggers cytokine cascades that may influence central neurotransmission through the vagus nerve and metabolic signals. In addition, Lion’s Mane shows a prebiotic effect on Lactobacillus and Bifidobacterium.
We still do not know to what extent the observed effects result from a direct influence on the brain and to what extent from modulation of the gut-brain axis. Most likely from both, in proportions that vary from person to person.
What lion’s mane does not do
Lion’s Mane does not cure Alzheimer’s disease or other neurodegenerative diseases. NGF and BDNF support is a physiological mechanism described in studies of the raw material, not a pharmacological intervention in an ongoing pathology. Nor does it raise IQ or memory in healthy adults in a way measurable by standard intelligence tests. It does not replace antidepressant or anxiolytic medicines. It is also not an acute stimulant like caffeine; the observations described accumulate over weeks and months.
How to take lion’s mane: the protocol
Time and serving
In the morning or at noon, up to 2 pm. Lion’s Mane is subtly activating, so in the evening it may make it harder to fall asleep for sensitive people. If you work shifts, adjust the time to your circadian rhythm.
In the cited RCTs effective doses range from 1.5 g/day (Nagano 2010) to 3 g/day (Mori 2009). In practice 1-3 g of extract a day is used. Prevention and everyday concentration: 1-1.5 g/day. Targeted protocols: 2-3 g/day. Above 3 g there is no strong evidence of greater efficacy and gastric tolerance may worsen. Do not exceed the recommended daily serving.
With what and for how long
Hericenones are lipophilic, so they absorb better in the presence of fat: morning coffee with a little fat (ghee, MCT, cream), cacao on plant milk, oatmeal with nut butter, an avocado smoothie. β-glucans and ergothioneine do not require fat.
The classic rhythm is 5 days on, 2 days off. Full cycle: a minimum of 90 days of regular use. Lion’s Mane is a classic example of a mushroom where regularity yields observation and occasional use does not.
What to observe over time
1-2 weeks: subtle changes in the quality of concentration, sometimes a quicker „start" to morning work, a slight change in digestion (prebiotic effect).
2-4 weeks: an easier return to demanding tasks.
8-12 weeks: a fuller observation in line with Mori 2009.
Four weeks after stopping, the difference fades (Mori 2009), which is an argument for regularity and a long cycle. It is worth noting subjective indicators: quality of concentration morning and afternoon, clarity of thinking, digestion and regularity.
What to combine lion’s mane with: synergy protocols
Lion’s Mane + Cordyceps: morning and focus
The most popular protocol for people doing intensive mental work. Cordyceps tonifies Kidney Yang and supports energy economy, Lion’s Mane supports NGF and clarity of thinking. Cordyceps 1 g in the morning, Lion’s Mane 1-1.5 g in the morning. Duration: 8-12 weeks.
Pair with:Cordyceps
Lion’s Mane + Reishi: day and evening
A classic daily protocol. Lion’s Mane in the morning (CNS activation), Reishi in the evening (HPA-axis regulation, wind-down). Lion’s Mane 1-2 g in the morning, Reishi 1-2 g in the evening. Duration: 8-12 weeks.
Pair with:Reishi
Lion’s Mane + Tremella: the neurotrophic axis
A complementary NGF axis. A classic protocol for people 50+ aimed at memory. Lion’s Mane 1-2 g in the morning, Tremella 1 g in the evening. Duration: 12 weeks.
Pair with:Tremella
Lion’s Mane + Chaga: antioxidation
Chaga is the strongest antioxidant among functional mushrooms, Lion’s Mane supports neuroplasticity. Lion’s Mane 1-2 g in the morning, Chaga 1-2 g in the morning or before noon. Duration: 8-12 weeks.
Pair with:Chaga
Lion’s Mane + Coriolus: the gut-brain axis after infection
Coriolus rebuilds the microbiota and stimulates innate immunity, Lion’s Mane supports clarity of thinking. Lion’s Mane 1-2 g in the morning, Coriolus 2 g before noon. Duration: 8-12 weeks.
Pair with:Coriolus
Lion’s Mane in Traditional Chinese Medicine
Lion’s Mane in the classical Chinese and Japanese Materia Medica occupies a place different from most functional mushrooms. It is not a Qi tonic in the classical sense (like Cordyceps or Reishi), but a mushroom combining support for digestion and mental work.
This is a frame of cultural observation, not a medical diagnosis. Concepts such as Qi, Shen or meridian do not correspond one to one with Western anatomy or physiology.

Frequently asked questions
- Is soplówka jeżowata the same as Lion’s Mane?
- Yes. Hericium erinaceus = Lion’s Mane (English) = soplówka jeżowata (Polish) = yamabushitake (Japanese) = hou tou gu (Chinese). One species, many cultural names.
- How does a fruiting-body extract differ from mycelium on grain?
- The fruiting body is the „fruit" of the mushroom, where hericenones and a fuller β-glucan profile concentrate. Mycelium is most often grown on grain (rice, oats), where the final product is 70-85% grain substrate. Aloha Fungi works only with the fractionally extracted fruiting body.
- After how long will I notice a difference?
- In the Mori 2009 RCT measurable changes appeared gradually over 8-16 weeks. Subjective first signals usually 2-4 weeks. We recommend a protocol of at least 90 days with regularity.
- Can it be taken with coffee?
- Yes, combining it with coffee is common and no interactions are described. Hericenones absorb better with fat, so coffee with a little MCT, ghee or cream is a good pairing.
- Is Lion’s Mane addictive?
- No. The described mechanism of action does not involve dopaminergic pathways or addiction receptors. After stopping, the observed effect fades within 4 weeks (Mori 2009), with no withdrawal syndrome.
- Are there Polish studies on Lion’s Mane?
- Yes. The first Polish RCT (HECOG, NCT07405632) at SWPS University in Warsaw was completed in October 2025 (n=85, 8 weeks). The results were not yet published at the time of writing this page (May 2026). Research on mushroom polysaccharides is also conducted by prof. Bożena Muszyńska at Collegium Medicum UJ.
- PRIME or LONGEVITY to start?
- LONGEVITY by default, as the gentler everyday line. Choose PRIME if you run an intensive, targeted protocol, already know Lion’s Mane and want a higher concentration of active fractions. Individual matching during a free consultation.
