While bioavailablity is related to to absorption, it is not quite that simple. The term, bioavailablity, is defined/used somewhat differently in the nutritional sciences than it is for pharmacology. For pharmacology, bioavailablity refers to the degree of activity or amount of an administered drug that becomes available for activity in the target tissue. For nutrients, including nutritional supplements, the concept of bioavailablity appears to be less clearly defined.
