Abstract
There is a connection between bioavailability and absorption. In the field of pharmacology, this is referred to as a category of absorption and is defined as the proportion of a particular dosage of a drug that does not change and is absorbed into the systemic circulation. Both the overall absorption of medications and their specific bioavailability are important factors to consider in treatment. In this paper, we will go into great detail about the bioavailability of phytochemicals. We will also discuss the factors that influence bioavailability, the processes that improve bioavailability, and the phytochemicals that act as important bio enhancers, which are agents that improve the bioavailability of drugs.
