Lion's mane mushrooms, also known as Hericium erinaceus, hou tou gu, or yamabushitake, are large, white, shaggy mushrooms that resemble a lion's mane. They have been used in traditional Chinese medicine and Native American healing practices for their potential medicinal properties, particularly for brain health. Recent studies suggest that lion's mane mushrooms may increase grey matter in the brain by stimulating nerve growth and promoting brain cell growth, which could lead to improved cognitive function and memory retention. While most research has been conducted on animals, limited human studies have shown promising results in healthy adults and those with mild cognitive impairment. However, more research is needed to confirm the effects of lion's mane mushrooms on brain health in humans.

They are large, white, shaggy mushrooms that resemble a lion's mane as they grow. They contain bioactive substances that have many beneficial effects on the body, especially the brain.
Research has found that lion's mane mushrooms contain compounds that stimulate the production of nerve growth factors, which help grow brain cells and may enhance memory and focus. In one study, researchers exposed neurons derived from rat embryos to lion's mane mushroom extracts for 24 hours and found that the neurons exposed to the extracts were up to twice as long as those not exposed. Another study found that mice given lion's mane mushroom supplements showed improved memory in a maze test.
Lion's mane mushrooms have also been found to have anti-inflammatory effects, which can reduce symptoms of anxiety and depression in mice. Additionally, they may help protect against Alzheimer's disease, a degenerative brain disease. A 2020 study found that supplementation with lion's mane mushroom daily for 49 weeks significantly improved cognitive test scores in people with mild Alzheimer's disease compared to a placebo.
While the potential benefits of lion's mane mushrooms are promising, it is important to note that most of the research has been conducted on animals or in test tubes. More human studies are needed to determine the effectiveness of lion's mane mushrooms in improving memory and focus. However, one small study of menopausal women found that consuming lion's mane mushrooms daily for one month helped reduce self-reported feelings of irritation and anxiety.
Lion's mane mushrooms can be found fresh, dried, or as supplements in specialty grocery and health food stores, as well as online. However, it is important to do your research and ensure you are purchasing from a trusted source with good reviews.

The lion's mane mushroom, or Hericium erinaceus, has been used in traditional Chinese medicine for centuries. It is believed to have a range of health benefits, particularly for the brain, heart, and gut.
One of the most promising potential benefits of lion's mane mushrooms is their ability to protect against Alzheimer's disease. Animal studies have found that lion's mane may help prevent and treat this degenerative brain disease. In mice, lion's mane mushroom extract has been shown to reduce symptoms of memory loss and prevent neuronal damage caused by amyloid-beta plaques, which are a hallmark of Alzheimer's.
A 2020 study in humans found that daily supplementation with lion's mane mushroom for 49 weeks improved cognitive test scores in people with mild Alzheimer's disease compared to a placebo group. The ability of lion's mane to promote nerve growth and protect the brain from Alzheimer's-related damage is believed to be responsible for these beneficial effects.
While the current research is promising, it is important to note that most studies on lion's mane mushrooms and Alzheimer's disease have been conducted on animals or in test tubes. More human studies are needed to confirm the efficacy of lion's mane mushrooms in protecting against Alzheimer's disease.
In addition to its potential benefits for Alzheimer's, lion's mane has also been shown to have positive effects on cognitive function, stress, and mood in healthy young adults. A 2023 randomized, double-blind, placebo-controlled study found that a single dose of lion's mane mushroom improved performance on a cognitive task, and a 28-day supplementation resulted in a trend towards reduced subjective stress.
