About

Panax Ginseng is a traditional herbal remedy whose active ginsenosides modulate cholinergic, glutamatergic, and GABAergic neurotransmission. Studies show subjects taking Panax ginseng experienced less mental fatigue during extended cognitive testing and had more sustained energy for visual processing assessments.

How It Works

Active ginsenosides modulate cholinergic, glutamatergic, and GABAergic neurotransmission; enhance cerebral blood flow; exhibit anti-inflammatory and antioxidant neuroprotection; may promote neurogenesis via BDNF and NGF expression.
