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.

Schisandra berries contain lignans (schisandrin A, B, C; gomisin A, N) that are the primary bioactives. Schisandrin B is a potent inducer of hepatic Phase I (CYP450) and Phase II (glutathione S-transferase, UDP-glucuronosyltransferase) detoxification enzymes. Schisandra activates Nrf2/ARE pathway, increases glutathione synthesis, and has hepatoprotective effects by stabilizing hepatocyte membranes. It modulates the HPA axis, reduces cortisol, enhances mental performance under stress via cholinergic and catecholaminergic modulation, and improves mitochondrial function through enhanced cytochrome c oxidase activity.
