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.

Tongkat Ali contains quassinoids (eurycomanone, eurycomanol) and bioactive peptides (eurypeptides). Primary mechanisms: reduces SHBG binding, freeing testosterone; inhibits aromatase (CYP19A1), reducing estrogen conversion; modulates the HPA axis reducing cortisol; stimulates Leydig cell steroidogenesis via cAMP pathway activation; and may inhibit phosphodiesterase (PDE) enzymes. The net effect is increased free testosterone, improved testosterone:cortisol ratio, and enhanced libido via dopaminergic and NO-mediated pathways in erectile tissue.
