Contains hericenones (fruiting body) and erinacines (mycelium) that stimulate nerve growth factor (NGF) synthesis in glial cells via activation of the JNK pathway. Erinacines cross the blood-brain barrier via passive diffusion and act as potent neurotrophin-stimulating compounds, activating the TrkA receptor and downstream ERK1/2 signaling cascades to promote hippocampal neurogenesis and synaptic plasticity. Also demonstrates anti-inflammatory activity through suppression of NF-kB and upregulation of BDNF expression.

Reishi contains triterpenoids (ganoderic acids, >130 identified) and polysaccharides (beta-glucans). Ganoderic acids inhibit histamine release, 5-alpha-reductase (DHT reduction), and ACE (angiotensin-converting enzyme). Beta-glucans (1,3/1,6-D-glucan) activate innate immunity via Dectin-1, CR3, and TLR-2 receptors on macrophages, dendritic cells, and NK cells. Reishi modulates the adaptive immune system by promoting Th1/Th2 balance and enhancing regulatory T-cell function. It also supports GABAergic signaling (calming effect), inhibits NF-kB, and modulates gut microbiome composition. Triterpenes support liver function via Phase I/II enzyme modulation.
