Bioavailability is a key concept in pharmacology and nutrition, referring to the rate and extent to which a substance is absorbed into the bloodstream and made available at the site of physiological activity. This concept is crucial for both pharmaceuticals and nutraceuticals, as it determines the effectiveness of drugs and dietary supplements. | Bioavailability is a key concept in pharmacology and nutrition, referring to the rate and extent to which a substance is absorbed into the bloodstream and made available at the site of physiological activity.
