About

Reishi is a medicinal mushroom used for over 2,000 years in traditional Asian medicine for calming the mind. Research suggests its triterpenes may modulate GABAergic neurotransmission, while polysaccharides support immune function that may indirectly influence sleep regulation.

How It Works

Triterpenes (ganoderic acids) modulate GABAergic neurotransmission; polysaccharides support immune-mediated sleep regulation.
