Lion's mane mushrooms may double neuron growth
Lion's mane mushrooms, scientifically known as Hericium erinaceus, have been used in traditional Chinese medicine for years. They are believed to have various health benefits, including the potential to stimulate neuron repair and promote nerve growth.
Recent studies have found that lion's mane mushrooms contain two unique compounds, hericenones and erinacines, which can stimulate the growth of brain cells. In one study, nerve cells exposed to compounds isolated from lion's mane mushrooms showed significant neuron growth, with hericene A and NDPIH having the most substantial impact.
Further analysis of cells from the hippocampus region of the brain supported these findings. Researchers found that mice supplemented with lion's mane mushroom crude extracts performed significantly better in a maze test, indicating enhanced recognition memory.
Additionally, animal studies suggest that lion's mane mushrooms may protect against Alzheimer's disease and dementia by reducing symptoms of memory loss and preventing neuronal damage caused by amyloid-beta plaques. However, it is important to note that research on the effects of lion's mane mushrooms on cognitive function and mood is still in its early stages, with most studies conducted on older adult samples or specific clinical samples.
While the potential benefits of lion's mane mushrooms are promising, more studies involving humans are needed to confirm their efficacy and safety. Dr. Kelly Johnson-Arbor, a medical toxicologist, cautioned that the findings from in vitro and mouse investigations may not directly apply to humans. Furthermore, the dietary supplement industry is highly unregulated, and the potential side effects of lion's mane mushroom extract in humans are still unknown.

Lion's mane may help protect against Alzheimer's disease
Lion's mane mushrooms have been studied for their potential to improve brain health and protect against Alzheimer's disease. Alzheimer's disease is a degenerative brain condition that causes progressive memory loss. The potential benefits of lion's mane mushrooms in this regard are attributed to their ability to stimulate the growth of brain cells and protect neurons.
Research has shown that lion's mane mushrooms contain two unique compounds, hericenones and erinacines, which can promote nerve growth and repair. Animal studies have found that these compounds may help protect against Alzheimer's disease by reducing symptoms of memory loss and preventing neuronal damage caused by amyloid-beta plaques, which are characteristic of the disease.
A 2020 study found that daily supplementation with 1 gram of lion's mane mushroom for 49 weeks significantly improved cognitive test scores in individuals with mild Alzheimer's disease compared to a placebo group. Additionally, pre-clinical testing and laboratory studies have demonstrated that compounds isolated from lion's mane mushrooms can increase the growth of brain cells and improve memory. Specifically, the active compounds were found to promote neuron projections, allowing neurons to extend and connect with other neurons, which is crucial for memory formation.
The potential neuroprotective effects of lion's mane mushrooms may be due to their ability to activate peripheral nerve regeneration and stimulate the growth and repair of nerve cells. While the current research is promising, more studies involving humans are needed to confirm the therapeutic effects of lion's mane mushrooms in protecting against Alzheimer's disease and improving brain health.
