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.

Shilajit is a mineral-rich exudate containing fulvic acid (60-80%), dibenzo-alpha-pyrones (DBPs), and over 85 minerals in ionic form. Fulvic acid acts as an electron shuttle in mitochondrial electron transport, enhancing CoQ10 function and ATP production. DBPs protect CoQ10 from oxidation, extending its functional half-life. Shilajit increases total and free testosterone by stimulating steroidogenesis and reducing SHBG. It also enhances mitochondrial membrane potential, acts as a potent antioxidant (fulvic acid neutralizes free radicals), and improves mineral absorption by forming bioavailable fulvic acid-mineral complexes.
