In pharmacology, bioavailability (BA) is a subcategory of absorption and is the fraction of an administered dose of unchanged drug that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs. By definition, when a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered via other routes (such as orally), its bioavailability generally decreases (due to incomplete absorption and first-pass metabolism) or may vary from patient to patient.
Calcium is the most plentiful element in the body, with most in the bones, teeth and nerves. Sadly, most people do not ingest nearly enough bioavailable calcium because when dairy products are pasteurized and homogenized, the calcium they contain is made less available to the body.n this case, calcium becomes biounavailable. That is, an excess occurs in the tissues but it is not available to the body. It becomes essentially a toxic mineral, causing calcium deposits in the joints, arteries, kidneys, brain and elsewhere.
