                                According to the Food and Drug Administration (FDA), bioavailability is defined as the rate and extent to which an active drug ingredient is absorbed from a drug product and becomes available at its site of action. Therefore, a higher bioavailability means that a greater proportion of a substance is absorbed and utilized by the body.
