Lion’s Mane Mushrooms [Amazing Brain Rebuilder]

As the struggle continues finding a cure for Alzheimer’s and dementia, science (and the rest of us) are turning to natural substances that have promise of healing and helping our brains. There are approximately 2,000 edible mushrooms and some of them are identified as having beneficial health properties. Of those, Lion’s Mane seems to be the most studied and identified as a Nootropic (substance for brain health). I’ll talk about the studies as well while we focus on the benefits.

Scientific name : Hericium erinaceus. Described as tasting like “seafood,” and compared to crab or lobster. There are some recipes out there for Lion’s Mane crab cakes. I’ll include one below.

Benefits of Lion’s Mane…

Nerve and Neuron Regeneration – Lion’s Mane Mushrooms

So healthy brains produce nerve growth factor (NGF), a family of proteins “responsible for maintenance, survival, and regeneration of neurons in adult life” (Sabaratnam [2013], NCBI). Lion’s Mane has a property that may help produce NGF and protect brain cells from cell death. Cell death is what happens in Alzheimer’s and dementia. Finding a substance that helps prevent this is amazing news.

Research has shown that lion’s mane extract can help speed recovery from brain and nervous system injuries. In one study on rats with nervous system injuries, lion’s mane reduced the recovery time by 23-41% (Julson, Healthline, 2018). Another study of older adults with mild cognitive impairment improved mental functioning while taking 3 grams of Lion’s Mane per day for four months. The improvement only lasted while they were taking it. But it works!

Scientists have yet to study the effects on humans with Alzheimer’s disease but the studies so far certainly warrant it. Hopefully, we’ll see some more proof soon. In the meantime, it is being hailed as a good preventive supplement.

Antioxidant and Heart Helper

Antioxidants fight both inflammation and oxidation. As you might have read in my Gut and Brain Connection article, inflammation is a contributing factor in diabetes, heart disease, and autoimmune diseases. Oxidation of cholesterol is what causes it to stick to arteries, hardening arteries, which can lead to heart disease (or worse).

In addition, studies in rats and mice have shown lion’s mane lowers triglyceride levels, even when on a high-fat diet. Given a daily dose of lion’s mane lowered triglyceride levels by 27%! The rats in a particular study also had 42% less weight gain after 28 days.

Another property in lion’s mane mushrooms is a compound called hericenone B, which can decrease the rate of blood clotting which also lowers the risk of heart attack and stroke.

Anti-Inflammatory and Gut Helper

Huge help for gut health. Researchers have found that the anti-inflammatory properties of Lion’s Mane mushrooms improve gut health for people with ulcerative colitis, Crohn’s disease and helps prevent the development of ulcers. It seems to help reduce inflammation in all parts of the colon and they have found that it might help prevent ulcers even better than some acid-lowering medications.

Lion’s mane helps lower blood sugar levels which are, of course, the cause of diabetes. Wow. Julson (2018) describes in her Healthline article that the way it does this is by blocking the enzyme alpha-glucosidase, which breaks down carbs. When blocked, the body is unable to digest carbs as effectively which then lowers blood sugar.

Another study on mice with diabetes also shows that it helps with diabetic nerve damage. Six weeks of daily lion’s mane mushroom extract greatly reduced pain, lowered blood sugar levels and increased antioxidant levels.

More research is needed with humans on the benefits for diabetic patients. But this shows promise.


Studies have been done with mice using lion’s mane as a treatment. The findings are that it helps kill cancer cells and also slows the growth of tumors. One study done with mice with colon cancer found that lion’s mane reduced the spread of cancer to the lungs by 69%.

Another study (on mice) showed that cancer-fighting effects worked better than cancer medications and had fewer side effects. More study is needed for its use in fighting cancer with humans.

Immune System Helper

Lion’s mane appears to boost the immune system, protecting against viruses and bad bacteria. Research has shown it boosts the immune system in the gut which helps protect against invaders through the mouth and nose.

This seems to be due to “beneficial changes in gut bacteria” (Julson, 2018) that stimulates the immune system. Back to the gut. 😉

With good gut health, brain health is greatly boosted.

Depression and Anxiety

It is said that up to one-third of people in developed countries have symptoms of anxiety and depression.

We also now know about the gut and brain connection and its effect on anxiety and depression. This may be why lion’s mane has been cited as helpful for depression and anxiety.

Since lion’s mane helps to regenerate brain cells and also helps improve functioning of the hippocampus (region of the brain responsible for processing memories and emotional responses), this may be another reason lion’s mane helps these two problems.

A small study of menopausal women were separated into two groups. One group was given lion’s mane daily for one month, the other group a placebo. The group taking lion’s mane reported reduced feelings of irritation and anxiety.

Side Effects

Very few side effects have been reported. A few people have reported rashes or difficulty breathing. Probably an allergic reaction. If you are allergic to mushrooms, then you don’t want to take lion’s mane.


Lion’s mane mushrooms are amazing. They help so many things. We talked about nerve and neuron regeneration, help with gut health and the immune system factor there, blood sugar lowering, lowering of triglycerides for heart health. Cancer helper and help for depression and anxiety. So many benefits. I’m including a video recipe for ‘crab cakes’ made with lion’s mane mushrooms if you can get a hold of some. 🙂 Enjoy!

  1. I guess you learn something new every day. While going through your site with all the medical style terms, I felt like I was back in Chicago, studying in my Mortuary Science class. We had to study the various terms related to the brain and anatomy. Anything to improve our immune system is important! Is Nootropics a new term? Too be honest I never heard of it. But what’s more important is educating readers on the importance of good health. 

    • Thank you for commenting. Nootropics is a fairly new term for substances that help the brain. I have an article here (What is in Nootropics?) you can check out to learn more about it. 🙂 

  2. Wow, I love your article about Lion’s Mane Mushroom. Honestly, I never heard this before. Thank you for sharing.

    I am surprised how much benefits we could get from this mushroom. We have a history of diabetes in the family and since I’m from the Philippines, we love rice! And we cannot go on a meal without rice! I think this might help lower down the risk. Will look into this more. Thank you!

  3. Wow! This is a wild discovery of the benefits associated with lions mane mushrooms and I must say, makes the article a worthy read for me. I never knew about lions mane mushroom before but after reading this post, I will surely try to make a cake using the recipe you shared. The benefits of this are just way beyond the ordinary and where I doff my hat for it was the regeneration part as tested on the animals. It was massive to know of and also the fact it can help cancer patients too. This might be the next gen miracle product.

  4. It’s a new wealth of information to know about the benefits of Lion’s Mane mushroom. Natural supplements are getting more popularized because it’s has been proven safe to take as prevention for many certain types of illnesses. I myself is a big believer that natural supplements is a big help to aid our healthy lifestyle. After all, medicines are originally derived from plants. 

    I haven’t been diagnosed with ulcer but I have problems with heartburn and GERD. There are times that I really get uncomfortable that I had to let go of my coffee and other favorite food. Good to know that Lion’s Mane has anti inflammatory properties that could help with these certain types of problems. It actually covers to cure a lot of sicknesses and diseases which is almost like an all-in-one supplement for brain and gut improvement. 

    Many of us rely on medicines once we learn about our sickness. It is always better to prevent than cure. With this, people should look for supplements that will work best for their condition. Thank you for the profound explanation on the benefits we can get from Lion’s Mane mushroom. With all the positive results from researches, I think this is going to be very well known as one of the best supplements. 

  5. Thanks for revealing such a beauty, this is actually the first time I’ll be hearing about lion mane mushroom and what it does,  it does seem to be a good option for boosting our cognitive abilities and repairing damaged tissues as well,  I’ve also come across good reviews about this supplement, and I would love to know if taking it excessively cause more harm than good mentally?

    • Thank you for your question. I think too much of anything is not a good thing. I don’t think it could cause more harm than good if you take a great deal of it but taking as directed would be ideal. 🙂
