What is Lion's Mane Mushroom?

Lion's mane (Hericium erinaceus) is a functional mushroom whose cascading white spines resemble its namesake. It is one of the few natural compounds shown in published research to support nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), proteins essential for neuron health and the brain's capacity for plasticity. Clinical studies have explored lion's mane for cognitive support in mild memory complaints, mood, and peripheral nerve health. Effects typically build over 8-12 weeks of consistent use, paralleling neuroplastic timescales. Dual-extracted forms (water and alcohol) deliver both the polysaccharides and the terpene compounds. Standard dose is 500-1,500 mg of fruiting body extract daily.
