Bioavailability Complex - a complex of plant extracts of natural origin (extract, ginger root, piperine, Cayenne, grapefruit), resulting in a high bioavailability of the individual components. Ginger root has a positive influence on the process of digestion and assimilation of nutrients; piperine (from black pepper extract) enhances the absorption of nutrients, including those contained in medicines and supplements; Cayenne pepper contains capsaicin, and grapefruit, thanks to the contained 6',7'-Dihydroxybergamottin , slows down activity of cytochrome P-450, which metabolites many nutrients retained in blood plasma. Action of grapefruit can be compared to the action of naringin and its metabolite: naringenin.
