This impressive finding from a 2012 study is just one of many scientific proofs revealing the potential of these special mushrooms. For your health, these unique-looking mushrooms can offer much more than just an interesting visual appeal.

Lion's mane supplements have recently garnered significant attention for their effects on the brain, heart, and digestive system. In fact, a 2020 study showed that people with mild Alzheimer's disease who took 1 gram of lion's mane mushroom daily for 49 weeks achieved significantly better cognitive function scores compared to the placebo group. Additionally, these mushrooms rank fourth in antioxidant activity among 14 different mushroom species studied in 2012. You might be surprised to learn that lion's mane can reduce triglyceride levels by as much as 27%—a finding from a 28-day study on rats.

In this article, you will learn about the latest scientific discoveries regarding lion's mane mushrooms from 2025, their effects on various bodily systems, and how to choose a quality supplement that best suits your needs.

Latest 2025 Research on Lion's Mane Mushrooms

The latest scientific research in 2025 has revealed a great deal of valuable information about the effects of lion's mane mushrooms on the human body. Unlike previous studies, this year, scientists focused not only on long-term use but also on the acute, single-dose effects in young, healthy adults—a group that was previously under-researched.

Key Findings from Clinical Trials

A randomized, double-blind, crossover study conducted in 2025 showed interesting results regarding a single dose of lion's mane. Researchers found that taking 3g of lion's mane extract (10:1 concentration) improved participants' performance on a motor skills test after 90 minutes14. This is the first scientific evidence that even a single dose of lion's mane can have a specific effect on psychomotor skills.

However, scientists also noted that a single dose did not lead to a significant overall improvement in cognitive functions or mood14. Nevertheless, data from another study revealed a tendency to reduce subjective stress after 28 days of daily use2. This indicates that a longer period of use may be needed to achieve mood improvement.

It is important to note that the 2025 studies showed different results depending on the type of cognitive test. For example, participants completed the Stroop task faster 60 minutes after a single dose2, but some executive function tests (Flanker and Trail Making) showed worse results14. Scientists emphasize that determining the optimal dose and the peak concentration of bioactive substances in the human brain are subjects for future research.

One interesting 2025 study specifically analyzed the extract of the lion's mane mushroom fruiting body, not the mycelium14. This aspect is significant because culinary use typically involves up to 300g of fresh fruiting body, not mycelium3.

Diseases Linked to Lion's Mane in Research

2025 research has expanded our understanding of lion's mane mushrooms' potential for various health conditions:

Cognitive Impairment and Alzheimer's Disease - A systematic review published in 2025 revealed that lion's mane could be a suitable future therapeutic treatment for the prevention and slowing of Alzheimer's disease progression15. The study showed that lion's mane extract enriched with erinacine A had the highest bioactive potential and best penetrated biological barriers15.

Stress and Anxiety - A new clinical trial launched in 2025 involves 135 young women (18-26 years old) who experience anxiety or stress16. This study aims to determine the effect of 28 days of lion's mane supplementation on well-being, using various standardized assessment tools16.

Inflammatory Bowel Diseases - New studies have shown that lion's mane, especially in combination with natural flavonoids/alkaloids and vitamins B3/B8, can reduce the inflammatory burden in inflammatory bowel disease tissues5.

Central Nervous System Disorders - 2025 studies confirmed previous data that lion's mane mushroom has the potential to treat various central nervous system disorders17. The mushroom possesses broad neuroprotective properties due to erinacine A's ability to reduce the accumulation of amyloid-beta plaques17.

Firstly, animal studies have shown that lion's mane extracts have anti-inflammatory effects that can reduce anxiety and depression symptoms in mice6. Additionally, research has revealed that these mushrooms can stimulate neural growth and improve hippocampus function—a brain area responsible for emotional responses and memory6.

Scientists are currently planning long-term studies to better understand the optimal dosage and the effects of long-term use. They also plan to investigate the peak concentration of bioactive substances in the human brain and evaluate potential mechanisms explaining regional effects, such as a possible increase in cerebral blood flow after lion's mane consumption14.

How Lion's Mane Supplements Affect Different Body Systems

The effects of lion's mane mushrooms on the human body are multifaceted and complex. Over the past few years, scientists have gained an increasing understanding of how these unique mushrooms affect different body systems. Let's delve deeper into how lion's mane alters our body's functions at a molecular level.

Brain Function and Memory

One of the most impressive properties of lion's mane is its ability to stimulate nerve growth factor (NGF) production. NGF is a protein essential for the growth, survival, and differentiation of neurons. Studies show that hericenones and erinacines found in lion's mane can cross the blood-brain barrier and directly stimulate NGF production in the brain.

From a cognitive function perspective, lion's mane supplements can improve your working memory. Experiments have shown that lion's mane extract enhances brain neuroplasticity – the ability to form new connections and adapt to changes. This leads to improved short-term memory, problem-solving abilities, and higher cognitive function.

However, it is important to understand that the effect on the brain is not instantaneous. Studies show that for optimal results, lion's mane should be taken regularly for at least 8-12 weeks. During this period, new connections form in your brain, and NGF helps restore and protect neuronal networks.

Immune System and Inflammation Reduction

Lion's mane mushroom is a powerful immunomodulator – it can "intelligently" strengthen the immune system. These mushrooms contain beta-glucans – polysaccharides that activate macrophages and natural killer (NK) cells, improving the body's defense against pathogens.

Reducing inflammatory processes is another important property of lion's mane. Studies have shown that these mushrooms:

Inhibit NF-κB signaling pathway activation, reducing the production of inflammatory cytokines
Decrease the amount of reactive oxygen species (ROS), thereby protecting cells from oxidative stress
Modulate T cell response, reducing the likelihood of autoimmune processes

It should be emphasized that lion's mane supplements can be particularly beneficial for those suffering from chronic inflammatory conditions, as they act systemically, not only suppressing symptoms of inflammation but also preventing their causes.

Digestive System and Gut Health

Recent studies reveal an interesting connection between lion's mane mushrooms and the gut microbiome. Lion's mane supplements can act as prebiotics, promoting the growth of beneficial bacteria in your gut. These mushrooms contain biologically active compounds that can selectively stimulate the growth of Bifidobacterium and Lactobacillus species, while inhibiting the proliferation of potentially harmful bacteria.

The gut-brain axis is another area where the benefits of lion's mane become evident. Since almost 90% of serotonin (the so-called "happiness hormone") is produced in the gut, a healthy gut microbiota is essential for good mood and mental health. Lion's mane mushroom, by improving the gut microbiome, indirectly affects brain function.

Nevertheless, lion's mane also directly affects the digestive system. These mushrooms contain compounds that protect the stomach lining from damage, inhibit the growth of Helicobacter pylori bacteria, and reduce inflammatory processes in the gut. Therefore, they can be beneficial for people with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or other digestive system problems.

Regular consumption of lion's mane supplements can improve the production and efficiency of digestive enzymes, leading to better nutrient absorption and a reduced likelihood of digestive discomfort. Accordingly, many users notice improved digestion, less bloating, and better overall well-being after just a few weeks of regular use.

Lion's Mane vs. Other Natural Supplements

While lion's mane mushrooms are gaining popularity for their properties, it's worth comparing how they differ from other adaptogenic mushrooms and supplements. This comparison will help you better understand which natural supplement is best suited for your needs.

Lion's Mane vs. Reishi: Which is Better for the Brain?

Both lion's mane and reishi mushrooms have a positive effect on brain activity, but their mechanisms of action differ. Lion's mane contains hericenone and erinacin compounds that stimulate the production of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF)7. These proteins help brain cells grow, repair, and protect themselves4.

A small clinical trial involving 41 participants found that lion's mane improved cognitive performance4. Another study with 31 healthy participants showed improved cognitive function scores after 12 weeks of use4. The greatest benefits were observed in older adults with mild cognitive impairment who consumed at least 3g daily for more than 12 weeks4.

In contrast, reishi mushrooms are more valued for their ability to:

Preserve spatial memory in low-oxygen environments4
Improve brain plasticity and maintain healthy neurotransmitter levels4
Increase BDNF levels and other growth factors that support synaptic plasticity4

One study found that people suffering from chronic pain felt more energetic and mentally clearer after 8 weeks of reishi extract consumption4. However, reishi is primarily used for its potential stress-reducing properties and immune system boosting8.

Conclusion: If you aim to improve memory and cognitive functions, lion's mane is a better choice4. Meanwhile, reishi is more suitable for stress management, sleep improvement, and mental clarity4.

How Lion's Mane Compares to Adaptogens

Lion's mane mushrooms possess adaptogenic properties, but they differ from other adaptogens. Rodent studies have shown that lion's mane extract can help restore stress-related changes in neurotransmitters (dopamine and serotonin)7. It also reduces levels of inflammatory markers interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α), which increase in response to stress7.

Furthermore, lion's mane restores stress-induced reductions in brain-derived neurotrophic factor (BDNF) in mice7. BDNF is a protein essential for brain function, and its reduced levels can increase susceptibility to stress and depression7.

However, reishi mushroom has specific adaptogenic properties that help support adrenal gland function7. These glands release cortisol – a hormone that helps the body respond to stress7. A small study with male athletes showed that a combination of reishi and Cordyceps mushrooms helped protect against stress-induced damage from excessive cycling load7.

Therefore, while both mushrooms are adaptogens, lion's mane is better suited for supporting brain functions in stressful situations, and reishi for managing physical stress and enhancing overall body resilience.

It's important to note that research on the adaptogenic properties of lion's mane is still in its early stages, and scientists need to conduct more human studies7. However, based on preliminary results, both mushrooms – lion's mane and reishi – can be beneficial for healthy people, just in different ways and for different problems.

How to Choose a Quality Lion's Mane Supplement

To ensure the effective benefits of lion's mane, it's crucial to know how to select quality supplements. Many options are available on the market, so it's important to know what to look for before purchasing this valuable mushroom supplement.

Capsules, Powders, or Tinctures – Which is More Effective?

Each form of lion's mane has its advantages. Capsules are the most convenient to use, have a longer shelf life, and are usually precisely dosed. However, their bioavailability may be lower than other forms.

Powders offer greater flexibility – you can mix them with drinks or food. First and foremost, powders often have better bioavailability than capsules. Studies show that hot beverages increase the absorption of active ingredients.

Tinctures are considered the most effective form because alcohol helps extract biologically active compounds and facilitates their absorption. However, it's worth noting that tinctures are not recommended for children and people who avoid alcohol.

What the Label Indicates: Hericenone and Erinacine Content

Quality lion's mane supplements always specify the amount of bioactive compounds. Hericenones are found in the mushroom's fruiting body, while erinacines are found in the mycelial part. According to the latest research, these compounds are responsible for many of the mushroom's beneficial properties.

Choose products that clearly state:

Beta-glucan content (at least 25%)
Concentration of hericenones and erinacines
Content of polyphenolic compounds

It is worth noting that fruiting body extracts contain more hericenones, while mycelium extracts contain more erinacines. However, the highest quality products are usually made from both parts, ensuring a broad spectrum of bioactive compounds.

Certificates and Quality Marks

High-quality lion's mane supplements usually have certificates from independent laboratories. The USDA Organic label guarantees that the mushrooms are grown without pesticides and other chemical substances. Also look for the GMP (Good Manufacturing Practice) label, which confirms that the product is manufactured according to strict quality standards.

Pay attention to the extraction method – hot water extraction extracts beta-glucans, while alcohol extraction extracts triterpenes and other alcohol-soluble compounds. Many high-quality products use a dual extraction method, combining both processes.

Finally, check the country of origin of the product – lion's mane supplements grown under organic conditions generally have more active ingredients than intensively grown mushrooms.

Who is lion's mane suitable for in 2025?
