Secondary messenger in insulin signaling cascade. Myo-inositol improves insulin sensitivity, reduces anxiety (via serotonin receptor modulation), and supports ovarian function. D-chiro-inositol complements by activating glycogen synthesis. 40:1 ratio mimics physiological balance.
Sulforaphane is the most potent natural activator of the Nrf2-ARE (antioxidant response element) pathway. It modifies Keap1 cysteine residues, releasing Nrf2 to translocate to the nucleus and upregulate >200 cytoprotective genes including NQO1, glutathione S-transferases, heme oxygenase-1, and UDP-glucuronosyltransferases (Phase II detox enzymes). It also inhibits HDAC activity (epigenetic modification), induces Phase II/III xenobiotic metabolism, and suppresses NF-kB inflammatory signaling.
