Lion’s mane
Lion’s mane (Hericium erinaceus), known in Japan as “the priest from the mountains,” is a well-researched mushroom that has been found to have some important bioactive compounds that seem to stimulate nerve growth factor (NGF) within the brain. NGF’s are proteins that are mainly responsible for the development, maintenance/repair, and survival of the brain. Lion’s mane appears to improve blood flow, which brings more oxygen to the brain. All of these factors may boost memory, improve focus, and bring mental clarity.
