Lion's mane mushrooms may boost the activity of the intestinal immune system
Lion's mane mushrooms, scientifically known as Hericium erinaceus, are large, white, shaggy mushrooms that resemble a lion's mane. They have been used in East Asian medical systems and Native American healing practices to improve general health.
Lion's mane mushrooms contain bioactive substances that have beneficial effects on the body, particularly the brain, heart, and gut. These mushrooms are also known to contain probiotics, which support the immune system and promote the growth of healthy gut bacteria.
Research on mice suggests that lion's mane mushrooms may boost the activity of the intestinal immune system. A 2012 study found that supplementing with lion's mane extract daily nearly quadrupled the lifespan of mice injected with a lethal dose of salmonella bacteria. Additionally, a 2023 animal study found that lion's mane supplementation promoted the growth of beneficial gut bacteria while reducing harmful bacteria, exhibiting a prebiotic effect.
The beneficial changes in gut bacteria stimulated by lion's mane mushrooms may contribute to their immune-boosting effects. These mushrooms may help protect the body from pathogens that enter the gut through the mouth or nose, potentially improving gastrointestinal health and managing disorders like inflammatory bowel syndrome (IBS) and inflammatory bowel disease (IBD).
While the research on the intestinal immune system is focused on animal studies, there is ongoing research on humans as well. A 2023 study involving 41 healthy adults aged 18-45 found that 28 days of lion's mane supplementation led to reported signs of reduced stress. This effect may be linked to the ability of lion's mane to stimulate nerve growth factor (NGF), which is associated with mood regulation.
