Whether you’re a “foodie,” self-proclaimed “health nut,” or just like to be in the know about natural foods and substances that are good for the human body… the lion’s mane mushroom needs to be on your radar.
Lion’s mane is a rather unusual looking fungus with a flowing white, hair-like appearance that’s beloved as both a tasty edible mushroom and a medicinal mushroom in Japan and China. It’s also found in North America and was known to the native people who used it in powdered form for its ability to treat and heal open wounds.
Similar to many other varieties of medicinal mushrooms, lion’s mane prefers to grow on fallen hardwood trees, especially the beech tree. Its scientific name is Hericium erinaceus while it’s also commonly known as yamabushitake in Japan and hóu tóu gu in China. You might also hear it referred to by other names including:
- Satyr’s Beard
- Monkey Head Mushroom
- Bearded Tooth Mushroom
Whether you’ve never heard tell of it, or have seen it for sale at a farmer’s market or Asian food store and wondered, what is lion’s mane mushroom good for?… you’ll want to read on to discover these 7 key lion’s mane mushroom health benefits.
Lion’s Mane Mushroom Studies: What the Research Shows
Scientific research over the past few decades has demonstrated that phytochemicals (natural, plant-based compounds) found within Hericium Erinaceus have some substantial benefits for health, including significant antioxidative activity.
The key compounds that appear to be chiefly responsible for the wide range of health benefits of lion’s mane mushroom are:
- beta-glucan polysaccharides
Lion’s mane mushroom is also known to be immunomodulatory, meaning that it can stimulate or suppress the immune system to enable it to better respond to threats.
Researchers have also reported cholesterol-lowering, nerve-protecting, nerve-regenerating, anti-diabetic, and anti-cancer properties. Want to discover more about the studied health benefits of lion’s mane? Let’s dive in!
#1. Lion’s Mane and the Nervous System
While a great deal of research has been done on this unusual mushroom, the “lion’s share” of that research (if you’ll pardon the pun) has been centered around its impact on the nervous system.
The nervous system comprises the brain, spinal cord, and the nerves that travel through the body. Everything works together to send and transmit nerve impulses, which are signals that control almost every function in the human body.
When an injury occurs to the brain or spinal cord, it can take a long time to heal. Excitingly, research on lion’s mane mushroom (let’s abbreviate that to LMM) has found that it helps to speed recovery from these types of injuries.
First off, LMM stimulates the production of nerve growth factor (NGF), a protein that stimulates nerve cells to grow. LMM also has neuroprotective properties and helps regenerate damaged cells.
LMM has also been widely studied with regard to its ability to help diseases of an aging nervous system, including:
- Parkinson’s disease
- Alzheimer’s disease
Since pharmaceutical companies have spent billions on finding medications to cure or at least relieve the symptoms of these serious health conditions with limited success, any progress in this area is incredibly promising. It’s important to point out, however, that the research into LMM’s potential benefit for these specific diseases is still preclinical (i.e., studied in test tubes and with laboratory animals).
Many Studies into
Researchers conducting studies on lion’s mane mushroom extracts have reported the following benefits in relation to the brain and nervous system:
- Provides potent antioxidants that afford anti-inflammatory protection to nerves [1,2].
- May improve mild cognitive impairment, both in animals and in people [3-5].
- Induces the secretion of nerve growth factor (NGF), a protein involved in the regulation of growth, maintenance, and survival of nerve fibers [6-8].
- Has neuroprotective properties [9-12].
- May help protect against and ease the symptoms of Alzheimer’s disease [13-16].
- Exerts a positive influence on the fatty material that wraps protectively around nerve cells and helps to transmit electrical signals from nerve to nerve. Known as myelin, it is the loss of this protective fatty layer around nerve cells that leads to diseases like Multiple Sclerosis and other neurodegenerative diseases .
- May promote nerve healing and regeneration following injury [18-20].
- May ease the symptoms of diabetic neuropathy .
- May help protect against the progression of aging and degeneration of the nervous system .
- May help to prevent the death of nerve cells and brain damage after seizures or stroke [23,24].
- Is easily absorbed by the brain and body as lion’s mane compounds have the ability to cross through the protective blood-brain barrier .
#2. Lion’s Mane and Depression & Anxiety
Antidepressants have become one of the most widely prescribed medications across the globe . The most popular variety is known as Selective Serotonin Reuptake Inhibitors (SSRIs), which enhance the neurotransmitter serotonin in the brain.
SSRIs are prescribed not only for depression but also for anxiety, eating disorders, obsessive-compulsive disorder, and a number of other mental health conditions.
A potential problem with SSRIs, however, is that they tend to come with a long list of side effects. Some of the more common SSRI side effects include :
- skin rashes
- muscle and joint pain
- digestive upset
- diminished sexual interest
Lion’s mane mushroom (LMM) has been reported to have anti-depressant activity, both in preclinical animal studies and human trials. The mycelia of the mushroom contain the phytochemical erinacine, which has been shown to help with the creation of neurotrophic factors in the brain .
Neurotrophic factors influence the growth, survival, and other functions of neurons (nerve cells). This action of erinacine has been hypothesized to play a role in depression.
Also, as noted before, LMM also stimulates the synthesis of nerve growth factor (NGF) which has an effect on brain and nervous system function .
A small 2010 human trial  found that only four weeks of taking LMM by 30 menopausal women reduced depression and anxiety in this group.
In an effort to better understand the effects of LMM on the brain and nervous system, a 2018 animal study  found that four weeks of administration promoted the generation of new nerve cells in the hippocampal region of the brain. (The hippocampus is involved in higher cognitive function, memory, and behavior). Researchers also found that LMM extracts reduced anxiety and depression in test animals.
Another 2018 animal study  reported that administration of LMM increased levels of the neurotransmitters norepinephrine, dopamine, and serotonin in the brain. LMM also blocked inflammatory pathways and regulated neurotrophic factors (as discussed above).
A 2019 human clinical trial  found that LMM given to 77 overweight or obese volunteers prone to binge eating decreased levels of depression, anxiety, and improved sleep after only eight weeks.
#3. Lion’s Mane and Hearing Loss
With so many studies demonstrating that LMM has profound effects on the nervous system, it’s no surprise that scientists have begun investigating if it can also help the nerves associated with hearing.
Presbycusis, the most common type of hearing loss, caused by the natural aging of the auditory system, has been shown in studies to often precede the onset of clinical dementia. Scientists also believe this hearing loss may also be an early warning signal of the onset of Alzheimer’s disease .
Human studies involving patients with sensorineural hearing defects (hearing loss where the root cause lies in the inner ear or the vestibulocochlear nerve) have found that the amount of circulating nerve growth factor is relatively low compared to the level found in patients with normal hearing .
A 2018 review of medical studies  investigating LMM for its effects on nerves discussed a particular study with aging mice. The results of the study indicated that the animals treated with LMM had significantly lower hearing thresholds compared with the control group. In other words, LMM helped the animals to hear better. LMM was also found to be effective in slowing hearing deterioration.
While this beneficial effect on hearing has not yet been proven in humans, it points once again to the significant beneficial role that lion’s mane mushroom is believed to have on nerve health.
#4. Lion’s Mane and the Immune System
Many studies [37-40] have concluded that lion’s mane mushrooms are immunomodulating agents, which means they have the ability to either stimulate or suppress the immune system (depending on what it may need) and may help the body fight infections, cancer, or other diseases.
This ability to modulate the immune system, in simpler terms, means that if the immune system is under-reacting to a threat (such as abnormal cell growth), LMM can help to augment its activity. In instances where the immune system is over-reacting, as it does with allergies and health problems like rheumatoid arthritis, LMM can act to help dampen down the immune response and inhibit its action.
#5. Lion’s Mane and the Digestive System
Many people are paying a lot more attention to their digestive health these days and for good reason. If you’re not absorbing food and nutrients properly due to digestive disorders such as “leaky gut” (intestinal permeability) or irritable bowel syndrome (IBS), you won’t be feeling as well as you might, nor operating at your best.
LMM has been shown in a number of studies to assist digestive health in several ways. Firstly, it acts as a prebiotic, providing food for and helping beneficial gut bacteria do their important work .
LMM also protects against the development of stomach ulcers by inhibiting the growth of a pathogen known as Helicobacter pylori which has been shown to be related to the development of stomach ulcers [42-45]. In addition, LMM exerts a protective effect on the inner layer of the digestive tract, known as the mucosa .
Both animal and human studies [47-53] have demonstrated that the anti-inflammatory benefits of LMM help to ease the symptoms of colitis and ulcerative colitis and other chronic inflammatory gut conditions.
#6. Lion’s Mane and Heart Health
There are a number of potential health benefits for the cardiovascular system when supplementing with lion’s mane mushroom.
Platelets are a necessary component of the blood. For instance, when you cut yourself, they keep you from bleeding to death by forming a clot at the site of the injury. However, when platelets begin to clump together abnormally, this can raise your risk of cardiovascular disease. A 2010 study  found that LMM inhibited the clumping of platelets.
High blood cholesterol levels can also increase the risk of cardiovascular disease. Several studies have demonstrated the ability of LMM to improve the metabolism of fats and to lower cholesterol levels [55-57].
Additionally, an in vitro (test tube) study found that LMM may help to prevent the oxidation of cholesterol in the bloodstream . The importance here is that cholesterol molecules, when oxidized, can attach to arterial walls and cause them to harden. This hardening has been found to increase the risk of stroke and heart attacks.
#7. Lion’s Mane and Healthy Cell Activity
LMM may also be beneficial for promoting healthy cellular activity due to its impressive array of antioxidants, beta-glucan polysaccharides, and other phytochemicals that work in a variety of ways within the body.
Preclinical studies with cells and animals have shown that lion’s mane mushrooms have significant antitumor effects against:
- breast cancer cells 
- colon cancer [60,61]
- leukemia [62-64]
- gastrointestinal cancer [65-67]
- cervical cancer 
- liver cancer cells [69-71]
Since there have been few to no human studies performed yet utilizing lion’s mane for cancer patients, it is NOT advisable to rely solely on lion’s mane for your cancer therapy.
Combined with other treatments, however, LMM may offer some benefits for cancer patients, especially insofar as they help to modulate the action of the immune system. Animal studies to date have shown that lion’s mane mushrooms are non-toxic and safe to use .
Lion’s Mane Mushroom Studies Reveal Even More Potential Health Benefits
If all of the amazing Lion’s mane mushroom health benefits listed above aren’t enough, researchers have turned up even MORE potential health benefits of lion’s mane.
Here’s a quick rundown of 7 ADDITIONAL lion’s mane mushroom benefits:
- Anti-viral – A 2010 study  found that LMM had anti-viral properties against Human Immunodeficiency Virus 1 (HIV-1), the virus that can lead to AIDS.
- Anti-microbial – A 2012 animal study  demonstrated the anti-microbial properties of LMM. Researchers found that daily supplementing the feed of mice infected with Salmonella typhimurium (which can cause food poisoning – gastroenteritis, typhoid fever, or enteric fever) with LMM nearly quadrupled their life span.
- Kidney-protective – A 2013 study  found that LMM had kidney-protective properties.
- Liver-protective – 2015 research  found that LMM was liver-protective.
- Obesity-related inflammation – A 2015 study  found that LMM prevented or eased the inflammation released by fat tissue associated with obesity.
- Anti-diabetic – Several preclinical studies [78,79] have demonstrated the anti-diabetic, blood-sugar-lowering properties of LMM.
- Muscle endurance – A 2019 animal study  found that supplementation with LMM enhanced and increased muscle endurance.
