Lion's Mane mushrooms (Hericium erinaceus) have shown promising potential in treating Alzheimer's disease due to their ability to stimulate the production of nerve growth factor (NGF). NGF is crucial in maintaining and repairing neurons—neurons are vital for cognitive function and memory.
While preliminary in vitro, human, and animal studies have demonstrated the positive effects of Lion's Mane on Alzheimer's-related symptoms, more extensive clinical trials are needed to confirm these findings. However, incorporating Lion's Mane into a holistic treatment plan, alongside other brain-boosting foods, exercise, sleep, and stress reduction, could be beneficial in managing Alzheimer's.
This detailed guide will examine how Lion's Mane helps people with Alzheimer's disease. Moreover, we will show you how to incorporate Lion's mane mushroom into your routine to enhance your cognitive health.
What Does the Science Say About Using Lion's Mane for Alzheimer's?
Overview of Existing Research
Lion's mane mushrooms (Hericium erinaceus), also known as H. Erinaceus, have been studied for their potential in treating Alzheimer's disease. The existing research includes in vitro, human, and animal studies investigating the effects of Lion's mane on the central nervous system.
In-Vitro Studies
In-vitro studies have shown that Lion's mane extract can promote nerve growth and reduce inflammation in nerve cells. These findings have prompted further investigation into the potential health benefits of Lion's mane mushrooms for Alzheimer's disease.
Animal Studies
Animal studies, particularly those involving transgenic mice, have demonstrated that Lion's mane supplements can improve cognitive performance and recognition memory in mice with Alzheimer's. Additionally, Lion's mane extract has been shown to reduce amyloid plaques, a hallmark of Alzheimer's disease, in the brains of these mice.
For example, in one study(1), the mice were given Lion's mane mushroom mycelia for 30 days, which attenuated the burden of the plaques of Alzheimer's in the brain.
In another study(2), Erinacine S and Erinacine A isolated from Lion's mane medicinal mushrooms attenuated the burden of Alzheimer's plaque in the cerebral cortex in mice. This resulted in improved cognitive functioning.
Similar results were seen in a 2018 study(3), where mice received Erinacine A and S for 30 days. Again, the results indicated the beneficial effects of Erinacine A and S, including the promotion of neurogenesis. In addition, results showed that Erinacine A improved cognitive performance.
In another study(4), the results revealed that Lion's mane prevented impairments of memory induced by the amyloid peptide, suggesting that this traditional Chinese medicine could effectively reduce the risk of Alzheimer's.
Human Studies
In one study(5) involving 50- to 80-year-old men and women diagnosed with cognitive impairment, the group receiving Lion's mane supplement showed significantly increased scores on the cognitive performance scale compared with the placebo group.
In a 2019 study(6), researchers explored the improvement of cognitive functions by oral intake of Hericium Erinaceus. A cognitive test designed to measure dementia showed that oral intake of Lion's mane mushroom significantly improved cognitive functions and prevented deterioration.

Lion's Mane and Alzheimer's: What’s the Relationship?
NGF is a protein essential for the growth, maintenance, and survival of nerve cells in the brain. It plays a crucial role in cognitive performance, including learning and memory. In Alzheimer's disease, NGF levels are often reduced, leading to the degeneration of brain cells and subsequent cognitive deficits.
Lion's mane promotes neurogenesis, enhancing NGF production in the brain.The bioactive compounds in this traditional Chinese medicine cross the blood-brain barrier and stimulate the production of nerve growth factors, such as NGF and brain-derived neurotrophic factor (BDNF).
This increase in NGF promotes nerve growth, nerve regeneration, and the formation of new brain cells, which can improve cognitive performance in individuals with mild cognitive impairment and mild Alzheimer's disease.
How to Incorporate Lion's Mane Mushroom into Your Diet
Recommended Forms and Dosage
Lion's mane supplements are available in several forms to promote brain health. These include:
- Lion's mane powder
- Lion's mane supplement
- Lion's mane mushroom extract
The optimal dosage of Lion's mane for Alzheimer's patients is still being researched; however, studies have shown significant improvements in cognitive performance and spatial memory at varying dosages. However, a recommended dosage is typically 500-3,000 mg daily, taken in divided doses.
Remember to follow the manufacturer's instructions and consult a healthcare professional before taking Lion's Mane for Alzheimer's or other cognitive issues.
Delicious and Nutritious Recipes
Lion's mane mushrooms can be easily incorporated into your daily diet. Fresh Lion's mane mushroom can be sautéed, added to soups, or used in stir-fries. Dried Lion's mane powder can be mixed into smoothies, oatmeal, or baked goods to boost brain health benefits.

Combining Lion's Mane Mushroom with Other Lifestyle Changes to Fight Alzheimer's Disease
How to Embrace a Holistic Approach to Alzheimer's Treatment
A holistic approach to Alzheimer's treatment is crucial to address the multifaceted nature of the disease effectively. While Lion's Mane mushrooms may offer potential benefits in improving cognitive performance and memory, it is essential to consider other lifestyle factors contributing to overall mental health.
Combining Lion's Mane with a comprehensive, well-rounded treatment plan can potentially improve the quality of life for those affected by Alzheimer's disease and their caregivers.
Combine Lion's Mane With Other Brain-Boosting Foods
In addition to incorporating Lion's Mane mushrooms into your diet, consuming other brain-boosting foods can further enhance cognitive function and overall mental health. Some of these foods include:
- Fatty fish,such as salmon, mackerel, and sardines: These are rich in omega-3 fatty acids that support brain function and reduce inflammation
- Berries, especially blueberries: These contain potent antioxidants that protect brain cells from damage
- Leafy green vegetables, such as kale, spinach, and collard greens: These are packed with essential nutrients and antioxidants that support cognitive performance
- Nuts and seeds, like walnuts and flaxseeds: These are rich in healthy fats, antioxidants, and vitamins that promote cognitive function
Invest Time In Exercise, Sleep, And Stress Reduction
Exercise, sleep, and stress reduction are critical components of a holistic approach to Alzheimer's treatment, as they play a significant role in maintaining overall mental health and cognitive performance.
Exercise
Regular physical activity has been shown(7) to improve cognitive function, increase blood flow to the brain, and reduce the risk of developing Alzheimer's disease. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week and muscle-strengthening activities two or more days per week.
