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.
