Erinacine A is a naturally occurring compound found only in Lion's Mane mycelium, not in the mushroom (fruiting body).
It has been studied for its role in supporting brain health, cognitive function, and healthy neurotrophic activity. Neurotrophic activity refers to the body's natural support system for neuron health, communication, and adaptability.
Each serving of Real Mycelium™ delivers 5 mg of Erinacine A.
