1. Boosts cognitive function and memory

Several studies have demonstrated that Lion’s Mane stimulates the production of Nerve Growth Factor (NGF), a protein that promotes the growth and maintenance of neurons. A 2013 study published in the International Journal of Medicinal Mushrooms confirmed that Lion’s Mane can improve cognitive function and reduce memory loss [PubMed PMID: 23735479].

2. Supports mental health and mood

According to a study published in Biomedical Research, consuming Lion’s Mane can reduce symptoms of anxiety and depression. The study attributes this effect to the mushroom’s ability to promote neurogenesis, especially in the hippocampus [PubMed PMID: 22897444].

3. Enhances immune function

Research suggests that Lion’s Mane can enhance the immune system by stimulating the production of bioactive polysaccharides. A study published in the Journal of Agricultural and Food Chemistry found that these polysaccharides boost immune response, particularly T-cells and macrophages [PubMed PMID: 20000778].

4. Reduces inflammation

Chronic inflammation is a key driver of many health problems, including cardiovascular diseases and autoimmune disorders. Lion’s Mane has shown anti-inflammatory effects in various animal studies, including research from the Journal of Natural Products, which found that the mushroom’s compounds reduced inflammation markers in rats [PubMed PMID: 20232895].

5. Improves gut health

A study published in Mycobiology demonstrated that Lion’s Mane acts as a prebiotic and may protect against stomach ulcers. The mushroom stimulates the growth of beneficial gut bacteria while inhibiting the growth of harmful bacteria like H. pylori [PubMed PMID: 23603942]. See more on mushrooms and digestive health.

6. Supports heart health

The beta-glucans found in Lion’s Mane are known to reduce cholesterol and support heart health. A 2011 study in the International Journal of Medicinal Mushrooms showed that these beta-glucans help lower LDL cholesterol while maintaining HDL levels [PubMed PMID: 22533468].

7. Promotes nerve regeneration

Lion’s Mane is one of the few natural substances that promote nerve regeneration. A 2010 study in Phytotherapy Research found that the mushroom supports the regeneration of peripheral nerves, making it beneficial for those recovering from nervous system injuries [PubMed PMID: 19682782].

8. Helps regulate blood sugar levels

A 2015 study published in Evidence-Based Complementary and Alternative Medicine found that Lion’s Mane helps regulate blood sugar levels, particularly in diabetic animals. This suggests potential benefits for people with diabetes [PubMed PMID: 26137358].

9. May help protect against dementia

Preclinical studies suggest that Lion’s Mane could help protect against neurodegenerative diseases like Alzheimer’s. A 2016 review in Frontiers in Aging Neuroscience highlighted Lion’s Mane’s ability to reduce symptoms of mild cognitive impairment in elderly adults [PubMed PMID: 27899971].

10. Enhances sleep quality

While research on Lion’s Mane and sleep is still emerging, preliminary studies suggest that the mushroom may promote relaxation and enhance sleep quality by reducing inflammation and improving brain health. Anecdotal reports from users suggest they experience better sleep after taking Lion’s Mane. For a dedicated sleep mushroom, many people pair it with Reishi for sleep and stress.

How to use Lion’s Mane powder

Lion’s Mane extract powder is easy to work into your day. A typical serving is about half a teaspoon to one teaspoon (roughly 1–2 g) daily. It has a mild, savoury flavour:
