For MEMORY, Lion’s Mane, known as ‘The Smart Mushroom’, is renowned for providing cognitive support, enhancing mental clarity, focus, and memory. This medicinal mushroom promotes nerve growth and helps brain cells form new connections. Lion’s Mane’s antioxidant and anti-inflammatory actions protect brain cells from injury. All of these actions help to improve learning ability and curb age-related memory decline.

Lion’s Mane, the botanical name of which is Hericium erinaceus, promotes nerve growth and repair, helping to maintain a healthy nervous system and optimal brain function. It stimulates the production of NGF (nerve growth factor), a protein essential for nerve cell growth, maintenance, and survival, and BDNF (Brain-Derived Neurotrophic Factor) which supports brain cell growth and synaptic plasticity, allowing the brain to form and strengthen connections.

Studies have shown that Lion’s Mane can counter age-related memory decline, assist in Alzheimer’s and dementia treatment, and enhance cognitive abilities, improving memory and learning deficits in healthy individuals. In a 2020 study of patients with mild Alzheimer’s disease it was found that taking 1 gram of Lion’s Mane for 49 weeks led to significantly improved cognitive test results.¹

Beyond promoting new cell growth, the active compounds in Lion’s Mane, hericenones and erinacine, have been found to stimulate the extension and branching of neurites (axon and dendrite projections) from neurons. This means they can help brain cells form new connections and strengthen existing ones, which is vital for learning and memory formation. Research on Lion’s Mane mushrooms has shown promising results. A 2019 study published in the journal Antioxidants examined the effects of a Lion’s Mane extract on brain cells with dementia. According to the researchers, these plant-based compounds helped the brain to generate new cells and improved signaling between them.²

Lion’s Mane may specifically improve the function of the hippocampus, a brain region critical for memory processing and emotional responses. Enhanced functioning of the hippocampus can contribute to better memory. In a notable 2018 study, Lion’s Mane mushroom extract helped improve spatial memory.³ A subsequent study showed that Lion’s Mane had a positive effect on the creation of new neurons in the hippocampus and cerebellum.⁴ The results suggest that Lion’s Mane extract can potentially boost memory.

Lion’s Mane also protects brain cells from cellular damage as it possesses antioxidant and anti-inflammatory properties. Chronic inflammation and oxidative stress can damage brain cells and contribute to cognitive decline. By reducing these harmful processes, Lion’s Mane may help protect neurons and maintain overall brain health, indirectly supporting memory function.

Oxidative stress is damage to cells, lipids, proteins, and DNA caused by free radicals that attach to tissues. Free radicals are unstable molecules with unpaired electrons, and they roam the body seeking other atoms or molecules to bond to. The chronic assault of ongoing oxidative injury can lead to long-term harm to brain and nerve cells, as well as muscles and other organs. Free oxygen radicals are produced naturally during normal metabolic processes such as clearing cellular waste, exercise, or mounting an inflammatory response; or from exposure to external environmental sources such as air pollutants, drugs, and industrial chemicals.

Oxidative stress results from an imbalance between excessive formation of damaging reactive oxygen derivatives versus their insufficient removal or neutralization. If antioxidant defenses become depleted, then there is a build-up of excessive oxidants.

Antioxidants such as Lion’s Mane are natural substances made in our bodies or taken from plant or mineral sources, that shield tissues from scavenging free radicals, reduce oxidative stress and cell damage, and quench harmful peroxides that damage tissues. Antioxidants also boost our own protective enzymes which protect against oxidative damage. Higher tissue levels of antioxidants also offset environmental oxidative injury from processed foods, sun, or pollutants, and they protect against neurological disorders and memory loss.

Anti-inflammatory compounds including Lion’s Mane are substances that reduce inflammation, a natural bodily response to injury or infection which can become chronic and then destructive. Anti-inflammatories work by either blocking the production of inflammatory mediators in the body or by calming the immune reaction. Inflammation is a normal body response to injuries or invaders like bacteria. It promotes healing and brings symptom relief. But chronic inflammation that occurs without injury or attack on the body, and which continues for too long — months or years — can cause a range of neurological and other disorders. Chronic inflammation occurs when the body continues to send inflammatory cells and substances into tissues although there is no danger to combat. Lion’s Mane protects healthy brain and nerve tissues from being hurt by chronic inflammation.

Lion’s Mane supports optimal brain function and protects memory by promoting nerve growth and safeguarding brain cells from damage, thus maintaining a healthy nervous system and overall cognitive health.

By promoting the repair of brain cells, there is evidence that Lion’s Mane can help recovery after brain or nervous system injuries, including mild concussions with mental fog and memory loss, or more major traumatic brain injury. Lion’s Mane also shows promise for reducing the severity of brain injury after a stroke, as it enhances the repair of neurons and nerve cells.

Lion’s Mane mushrooms are found on broad leaf trees and logs, appearing as a cascading white waterfall, and they are quite delicious. Rich in vitamins such as thiamine, riboflavin, and niacin, they are also a good source of essential minerals such as manganese, zinc, and potassium. Lion’s Mane mushrooms (or Hou Tou Gu) are a traditional time-honored Chinese medicine used for centuries, valued for improving focus and believed to benefit the five Yin organs — liver, spleen, heart, lungs and kidneys. Modern science confirms that Lion’s Mane has well-documented benefits for memory and brain health plus much more.

In our clinic, we look for well-established mushroom companies, with reliable quality control and preferably certified organic formulas. Our patients taking Lion’s Mane for 9 to 12 months have frequently reported less forgetfulness, better planning skills, improved memory for recent events, and greater mental clarity.

Recommendation: Lion’s Mane at 1,000 mg daily is an effective dose, best taken between meals or with a light snack, or as recommended by your healthcare provider.
