Lion's Mane (latin: Hericium erinaceous) contains two families of compounds: the hericinones and erinacines, that strongly stimulate the synthesis of Nerve Growth Factor (NGF). NGF promotes neuron repair and renewal, including myelination.

Both the erinacines produced by Lion’s Mane’s mycelium and the hericenones isolated from the fruiting body have been shown to promote the generation of Nerve Growth Factor (NGF) and MycoNutri Organic Lion's Mane contains Hericium erinaceus mycelial biomass and fruiting body together with ethanol extracts of both the mycelium and fruiting body in order to capture the full activity of this remarkable mushroom
