In another words, a product with very good quality raw materials however is made in such a manner that the tablet does not break down appropriately would have low bioavailability and would therefore not do the patient any good. Disintegration time is an illustration of a test which measures aspects of bioavailability; this is the time it takes beneath controlled conditions for a tablet to break down totally. When a supplement breaks down when it is assumed to, there is a bigger likelihood which it will be absorbed.
