Bioavailability

Bioavailability refers to the proportion of a substance, such as a drug or nutrient, that enters the bloodstream when introduced into the body and is made available for use or storage. For instance, when you take a medication, its bioavailability indicates how much of that drug effectively reaches your bloodstream to exert its effects. Factors like the method of administration, formulation, and individual differences in metabolism can influence bioavailability. Understanding this concept is crucial in fields like medicine and nutrition, as it helps determine the appropriate dosages and effectiveness of treatments or dietary supplements.
