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.
Gut metabolite of ellagitannins that activates mitophagy — selective clearance of damaged mitochondria. Improves mitochondrial function, muscle endurance, and cellular energy production. Only ~40% of population can produce it endogenously.
