Lion’s Mane (Hericium erinaceus) is unique in the mushroom family both in appearance and function. Lion’s Mane Mushroom is extremely effective at stimulating Nerve Growth Factor (NGF) in the brain.

Known for its powerful effects as a “brain tonic”, Lion’s Mane is said to have been used as a tea for thousands of years by Buddhist monks. To enhance brain power and heighten their ability to focus during meditation.

Lion’s Mane, as a nootropic, is a powerful catalyst for brain cell regeneration, helping improve memory and cognition.

The primary active compounds in Lion’s Mane are hericenones and erinacines. Erinacines help your brain produce more Nerve Growth Factor. Erinacines easily cross the blood-brain barrier to boost the production of neurons.

Lion’s Mane helps:

  • Nerve Growth Factor. Lion’s Mane Mushroom helps prevent and treat nerve damage in the brain. Once past the blood-brain barrier, Lion’s Mane stimulates the production of enzymes that release Nerve Growth Factor (NGF). Nerve regeneration helps relieve neurodegenerative disease symptoms such as Alzheimer’s, dementia, and Parkinson’s Disease.
  • Neurogenesis. Lion’s Mane stimulates the repair and creation of neurons. Boosting neurotransmitters and signaling that affect memory, learning, recall, and mood.
  • Brain Optimization. Lion’s Mane helps eliminate brain fog. Restoring memory and mental alertness. And improves anxiety and depression symptoms.

What is Lion’s Mane Mushroom?

Lion’s Mane (Hericium erinaceus) is a medicinal mushroom proven to benefit the brain, nerves, and immune system.

Unlike other mushrooms sporting a cap and stem, Lion’s Mane has long, flowing, white tendrils. Resembling a lion’s mane. Other names include Monkey’s Head, Bearded Tooth, Pom Pom Blanc, Hedgehog Mushroom, and Satyr’s Beard.

Lion's Mane Mushroom grows on trees
Lion’s Mane mushroom (Hericium erinaceus)

This parasitic fungus grows hanging off logs and trees. It is native to North America, Europe, and Southeast Asia. In Japan, it’s called yamabushitake or “those who sleep in mountains”. Referring to the Shugendo sect of hermit monks and their long, flowing robes.

As a nootropic, Lion’s Mane has been shown to be particularly effective in stimulating Nerve Growth Factor (NGF) in the brain.

NGF is produced in the hippocampus throughout life. Modulating cholinergic receptors and neuroplasticity.[i] And is essential for learning.

Nerve Growth Factor is a special protein that helps regenerate neurons. Lion’s Mane contains two unique classes of NGF’shericenones and erinacines, which easily cross the blood-brain barrier.

Lion’s Mane, like other medicinal mushrooms, contains high amounts of the antioxidant beta-glucoxylan, as well as four other polysaccharides and polypeptides. Having a significant impact on enhancing your immune system. And decreasing tumor growth.

Lion’s Mane has also been studied for its potential to reduce amyloid plaques. These clumps of beta-amyloid proteins block signals between neurons. They are implicated in Alzheimer’s and other neurodegenerative diseases.

Lions’ Mane is also used to treat Lyme’s Disease and digestive tract issues.

Here we’re talking about Lion’s Mane Mushroom and its effects on brain health and chemistry.

Lion's Mane boosts nerve growth factor in the brain

How does Lion’s Mane Work in the Brain?

Lion’s Mane boosts brain health and function in several ways. But two in particular stand out.

  1. Lion’s Mane Mushroom stimulates the synthesis of Nerve Growth Factor (NGF). NGF is a protein that plays a major role in the maintenance, survival, and regeneration of neurons.

NGF is required by your brain to keep neurons strong and healthy. When various neurological disorders occur, your brain is unable to produce its own internal source of NGF.

In a study done in Kuala Lumpur in 2013, scientists showed that Lion’s Mane extract induced NGF synthesis and promoted neurite outgrowth.[ii]

  1. Lion’s Mane is effective in reducing anxiety and depression. Some even call it the “smart mushroom” for its ability to improve cognition, memory, and act as an antidepressant.

A study by researchers in Japan worked with 30 women. The female subjects had been complaining about menopause, depression, sleep quality, and other issues.

The women were randomly assigned to receive Lion’s Mane-laced cookies or a placebo for 4 weeks. The researchers found that Lion’s Mane “has the possibility to reduce depression and anxiety, and these results suggest a different mechanism from the NGF-enhancing action of H. erinaceus”. [iii]

How things go bad

Science once believed that the brain could not grow new brain cells. Once our brains develop during childhood and we reach adulthood, we have all the brain cells we’ll ever have.

Now we know that neurons can regenerate. But that doesn’t mean they will regenerate. A number of health issues can contribute to neurodegeneration.declining nerve growth factor

↓ Decrease in Nerve Growth Factor = Decrease in Long-Term Potentiation affecting long-term memory[iv]

↓ Brain cells die and are not replaced

Neuroplasticity declines, resulting in poor memory

Neurotransmitters decline, resulting in anxiety, poor mood, and depression

All of these age-related changes are contributing factors to neurodegenerative diseases like Alzheimer’s, Parkinson’s, and others. And anxiety, depression, and mood disorders that affect quality of life.

Lion’s Mane benefits

At least a dozen peer-reviewed studies have been published on Lion’s Mane benefits to brain health since 1991. Dr. Kawagishi of Japan was the first to identify the properties of Nerve Growth Factor in Lion’s Mane Mushroom.[v]

In one double-blind, placebo-controlled trial, researchers in Japan worked with 50 – 80-year-old men and women. All suffered from mild cognitive impairment.

The trial subjects received four 250 mg tablets containing 96% dry powder of Yamabushitake (Lion’s Mane) three times a day for 16 weeks. The men and women were tested at 4, 8, 12, and 16 weeks.

In each testing period, subjects who had used Lion’s Mane showed significant improvements in cognitive scores. And their scores increased while supplementing with Lion’s Mane. But 4 weeks after stopping Lion’s mane supplementation, their cognitive scores decreased significantly.

The researchers concluded that Lion’s Mane Mushroom is effective in improving mild cognitive impairment.[vi]

How does Lion’s Mane feel?

You may not experience the effects of Lion’s Mane Mushroom supplementation immediately. But many users report a boost in mood and mental energy with continued use of Lion’s Mane.

Lion's Mane boosts moodSome report that it increases depth perception. And an improvement in the sense of smell.

Others testify to improved decision-makingproblem-solving, and learning. Likely due to Lion’s Mane’s ability to improve neuroplasticity.

The consensus is that Lion’s Mane Mushroom can lessen anxiety, reduce depression, and improve concentration.

Lion’s Mane Clinical Research

Lion’s Mane Mushroom has been used as a food and herbal medicine since ancient times in East Asia. And scientific research has reported that Lion’s Mane promotes Nerve Growth Factor in petri dishes, as well as in animal and human test subjects.

Lion’s Mane Prevents Cognitive Dysfunction

In this study, researchers examined the effects of Lion’s Mane on amyloid β(25-35) peptide-induced learning and memory deficits in mice. The amyloid β(25-35) peptide is implicated in diseases such as Alzheimer’s.

Mice were injected with the peptide on days 7 and 14 of the trial. And they were fed a diet containing Lion’s Mane for 23 days of the experiment. The results showed that Lion’s Mane prevented the short-term and visual recognition memory reductions normally induced by the amyloid β(25-35) peptide.

They concluded that Lion’s Mane Mushroom “may be useful in the prevention of cognitive dysfunction”.[vii]

Lion’s Mane Induces Nerve Growth Factor

In this trial, mice were fed Lion’s Mane 5% freeze-dried powdered extract for 7 days. Researchers found an increase in the level of Nerve Growth Factor (NGF) in the hippocampus of the mice. Concluding that Lion’s Mane “contains active compounds that stimulate NGF synthesis”.[viii]

Lion’s Mane Repairs Nerves

In this rat study, Lion’s Mane extract promoted neuronal regrowth after injury. Rats with gluteal nerve damage were able to walk again after consuming water containing Lion’s Mane extract.

The researchers concluded that Lion’s Mane regenerates damaged nerve cells. In this case, the reversal was so profound that the rats went from being totally disabled to walking again.[ix]

Lion's Mane prevents cognitive dysfunction

Lion’s Mane Dosage

Wondering how much Lion’s Mane to take? Dosing Lion’s Mane Mushroom depends on the extract’s strength.

For Lion’s Mane 10:1 extract (30% polysaccharide), the daily dosage is 500 – 1,000 mg taken 1 to 3 times per day. This means that if you choose a daily dose of 1,000 mg of Lion’s Mane extract, you should take 500 mg in the morning and another 500 mg at noon.

Other retail extracts of Lion’s Mane range from 300 mg to 3000 mg, dosed 1–3 times per day. Check the label and see what the manufacturer recommends. And when first using the supplement, start with the lowest dose and see how your body reacts.

Lion’s Mane Side Effects

Lion’s Mane Mushroom is non-toxic and considered very safe. So, very few side effects have been reported.

Some neurohackers report itchy skin from higher doses. Likely attributable to a boost in Nerve Growth Factor.

Lion’s Mane has been tested in animals, with no side effects or toxicity even at doses up to 5 grams per kilogram.

Best type of Lion’s Mane to buy

Lion’s Mane Mushroom (Hericium erinaceus), when used as a nootropic supplement, is usually offered as an extract. In powdered form, or in a capsule.

MindLab Pro with Lion's ManeLion’s Mane Mushroom can be found in some of the higher-quality pre-formulated nootropic stacks. For example, Click for Mind Lab Pro® contains 11 brain-enhancing nootropic compounds, including Lion’s Mane with the full fruit spectrum, including hericenones and erinacines.

I recommend Mind Lab Pro® because it addresses all aspects of anxiety resistance, memory, and cognitive enhancement, stabilizes mood, and promotes brain repair and maintenance.

This premium nootropic stack is designed to influence neurotransmitter levels, cognitive energy, brain waves, neuroprotection, and regeneration. See my Mind Lab Pro review for a detailed report.

When choosing a Lion’s Mane supplement, there’s debate over the best extraction method to achieve the mushroom’s full medicinal benefits. Some say your best option is a hot water extraction. Another says alcohol extraction. Another claims both are necessary.

But when it comes to mushrooms, saying that one is “more potent” than another is just too simplified to be true. This is as much an art as it is a science.

Much more important is choosing a supplement that includes Lion’s Mane Mushroom mycelium. In this mushroomthe fruiting body does not contain erinacines, which are compounds that boost Nerve Growth Factor (NGF).

The nootropic benefits of hericenones, found only in the mushroom’s fruiting body or top, help support your immune system and eliminate the Amyloid β(25-35) peptide implicated in diseases like Alzheimer’s.

The challenge is getting a Lion’s Mane Mushroom extract that contains the full spectrum found in both the mycelium and fruiting body. But the mushroom must be grown in liquid and not on a solid substrate like grain. Otherwise, you’ll get ground-up grain without the important erinacines needed for increased NGF.

Look at the manufacturer’s literature and marketing material and find out how their Lion’s Mane is grown. And read reviews on shopping sites and forums.

Types of Lion’s Mane available:

  • Plain Lion’s Mane: Pure, powdered mushroom. Often freeze-dried and the cheapest form available. Can be added to water, juice, or smoothies.
  • Lion’s Mane Extracts: A more potent form of mushroom. Often presented as 14:1 or 10:1 extracts (14 pounds or 10 pounds reduced to 1 pound of extract).

You will get 500 mg Lion’s Mane full-spectrum extract in Click for Mind Lab Pro®

If you want a standalone Lion’s Mane Extract, I recommend Real Mushrooms’ organic Lion’s Mane Extract

  • Standardized Lion’s Mane: Processed to provide exact levels of active ingredients. You can get Lion’s Mane standardized to 30% and 50% polysaccharides (including the active secondary metabolites hericenones and erinacines).
  • Lion’s Mane tea: Since this mushroom is popular in the kitchen, the taste is acceptable. But it’s hard to get a handle on how much of the active ingredient you’re actually getting.
  • Amycenone®/PLM-Fraction: This “branded” product is standardized to 0.5% Hericenones and 6% Amyloban. It seems to target a lesser-known Lion’s Mane active ingredient–Amyloban–which is positioned as a mushroom compound that fights beta-amyloid proteins. Originating in Japan, it is extremely expensive and may be found in a supplement called Amyloban®3399.

And if you decide to pick your own, before consuming any wild mushroom, make sure that it is accurately identified. Mushroom poisoning is a real problem if you pick the wrong one.

Nootropics Expert Recommendation

Lion’s Mane 500 – 2,000 mg per day

Nootropics Expert Tested and ApprovedI recommend using Lion’s Mane as a nootropic supplement.

Your body does not make Lion’s Mane on its own. So you need to take it as a supplement.

Lion’s Mane is especially helpful for regenerating brain cells. It prevents neurodegenerative diseases like Alzheimer’s and Parkinson’s.

And it boosts long-term potentiation for memory and mental sharpness. By stimulating Nerve Growth Factor.

Lion’s Mane also helps boost mood, tame anxiety, and relieve depression. For a better quality of life.

We suggest starting with a dose of 500 mg daily. The best human study used 3000 mg per day. But another researcher found that lower concentrations may stimulate NGF better than higher concentrations.[x]

Start at 500 mg per day and see how it works for you. If you don’t experience a benefit, boost Lion’s Mane in small increments of 250 mg per day until you notice an improvement. And make sure you are using a supplement containing mycelium and fruiting bodies grown in a liquid medium.

You can buy individual Lion’s Mane supplements. Or you could try my favorite pre-formulated nootropic stack, Click for Mind Lab Pro®, which includes the full spectrum, including hericenones and erinacines found in Lion’s Mane Mushroom.

Mind Lab Pro contains a synergistic blend of 11 brain-enhancing nootropics covering all aspects of cognition and brain health. See my full Mind Lab Pro review for more.

Lion’s Mane is a great complement to a nootropic stack that includes AniracetamCDP-Choline, and Omega-3s for an immediate cognitive boost.

Hi. Is it true that reishi and Lion’s Mane affect DHT? If it is true, how much? Is there any way to avoid it? Taking pregnolone, for example.

    David Tomen
    June 5, 2025

    I have not seen any evidence that either mushroom affects DHT. If you find something please let me know. Just keep in mind that evidence needs to be a peer-reviewed clinical study and not someone person’s blog.

Hi David,
¿What quantity do you recommend for lion’s mane in powder form?
I hope my English is good: )

    David Tomen
    April 6, 2025

    Lili, your English is perfect!

    Regular powdered Lion’s Mane Mushroom recommended dosage up to 3 grams or 3,000 mg per day. And it is best to use a small scale to weigh it like this one: https://geni.us/6qB0s

Hi David, I ask to my supplier about the ratio of lion mane extract. they say the ratio is 5:1.

Should I increase the dosage (1000~2000mg/day) or better yet, find another supplier? The problem is that in my country there is only 1 that supplies extracts :(. Or maybe there are recommendations from suppliers who are used to shipping to Indonesia? Thanks in advance.

    David Tomen
    December 3, 2024

    Risky, they key is getting a Lion’s Mane extract that includes both the fruiting body and mycelium. Because you have one of two active compounds in each part of this mushroom which is unique compared to other nootropic mushrooms which is the fruiting body only. That is more important that the ‘ratio’.

      Rizky
      December 12, 2024

      Oh, I see, thank you!

Hi David

I bought Lion’s Mane Mushroom(30% extract) that is all it says on the labels if it’s 14:1 or 10:1 extract or what i don’t know. They say to take 2 x 1000mg in the morning but i want to start with one like you said. Start with the min dose and see how it reacts with my body.

The question i have is does Lion’s Mane Mushroom(30% extract) have any effect on serotonin and dopamine like does it increase serotonin and dopamine levels? Is it safe to take with antidepressants?

I don’t see you mentioning that it increases serotonin and dopamine but on other websites they say so so i just want your opinion if i can take it with SSRI’s?

    David Tomen
    August 6, 2024

    Anthony, Lion’s Mane is not contraindicate with any drug that I have been able to find. And no, it does not increase dopamine or serotonin. But Lion’s Mane stimulates the repair and creation of neurons. Which may affect how those neurotransmitters work in your brain.

      anthony
      August 10, 2024

      Hi David

      Not sure what your saying. Are you saying that Lion’s mane repair and creates neurons that help release serotonin and dopamine in time those neurons will release more dopamine or serotonin in your brain. Does it do the same with gaba receptors?

      Just want to be clear so i can take Lion’s mane and SSRI’s without any worry about serotonin syndrome?

        David Tomen
        August 13, 2024

        Anthony, Lion’s Mane Mushroom can NOT produce Serotonin Syndrome no matter how you use it.

June 6, 2024

I am curious on how to consume lion’s mane for the health and nootropic benefits. I am growing some from a kit and I intend on eating them, as I have heard they are quite tasty. The alleged tastiness, in fact is what made me interested on them and I found about all of those possible positive effects later.

But everywhere I look, I see people recommending either a lion’s mane extract or a powder made from the dry mushrooms. It seems that all authoritative published research on it has also utilized a powder or an extract, rather than the fresh mushrooms. I am now left in doubt: how much lion’s mane would I need to eat per day to get the same benefits as the powders/extracts? Does cooking them destroy the hericenones and erinacines?

Further, I have seem claims that lion’s mane tea was the traditional way of consumption. would making this tea be a better way to get the nootropic effects than just eating them?

    David Tomen
    June 10, 2024

    Eduardo, you will get more of the benefit from an extract of a herb or mushroom because the active compounds are more concentrated. But fresh is great and will still provide the nootropic benefits you read about in the review above. Making a tea from Lion’s Mane is one way of consuming it. Another is simply using it as is. Cooking them will not destroy the hericenones and erinacines as long as it is not really high heat.

Thanks David for your suggestion,
the company Genius does not deliver to Germany, but I found Genius mushrooms on iherb, it is a combination between lion’s mane, reishi, and cordyceps, do you know if there is any contradiction between reishi, cordyceps and ssri, because i did not find them on the nootropics list on your website, I already tested lion’s mane so i know it is not contradicted with ssri.
thanks a lot for your help.

    David Tomen
    March 29, 2024

    Rooney, there are no contraindications between nootropic mushrooms.

Rooney
March 21, 2024

Hello David,

can you recommend another brand of Lion’s mane, I tried that of real mushroom, unfortunately, I got stomach pain after one hour of taking it, I would like to try one else, is it difficult to find one which contains both fruiting body and mycelium.
Thank you very much

    David Tomen
    March 21, 2024

    Rooney, try this one: https://geni.us/TLp2w. It is very difficult to get both active compounds in a Lion’s Mane extract supplement. But that one has great reviews so worth trying.
