How it works

Human trials suggest potential for improving mild cognitive impairment and reducing symptoms of anxiety and depression. Most research focuses on its ability to stimulate nerve growth factor (NGF) in the brain, though larger studies are needed to confirm long-term efficacy.

Contains hericenones and erinacines that stimulate the synthesis of Nerve Growth Factor (NGF) and can cross the blood-brain barrier to support neuroplasticity.
