It is a general impression that the more you consume nutrients, the more will be made use of by the body. But biologically speaking, this is not always true. Some nutrients taken at a higher dose will actually negate the benefit and will not be absorbed by the body.  Ideally speaking,  the less,  the best.

Similarly if one believes that since Bioperine is sourced out of black pepper, all one need to do is increase the consumption of black pepper. Again you have gone wrong, for the direct intake of black pepper will not help achieve enhanced nutrient absorption.

According to clinical reports, having Bioperine® in the “right place at the right time” in the digestive tract with supplemented nutrient results in enhanced absorption. So Bioperine when taken during illness will have the best nutrient absorption. Besides if piperine were to remain captive in the form of raw black pepper, it will take time for its bioavailability enhancing property to be released. Therefore, a purified extract of piperine is necessary to get the increased absorption.
