Assessment of Digestion, Absorption, and Metabolism of Nanoencapsulated Phytochemicals Using In Vitro and In Vivo Models: A Perspective Paper

:nanoencapsulation delivery systems have been used to enhance the absorption and bioefficacy of phytochemicals.With modified physical and chemical properties, nanoencapsulated phytochemicals differ from their free forms in digestion,absorption, and metabolism. These pharmacokinetic processes can be assessed using a combination of variousin vitro/in vivomodelsand analytical strategies, but each approach has its limitations. The correlation between current models and physiological conditionsand their feasibility for nanoencapsulation systems require further validation. More detailed studies are still needed to clarify hownanoencapsulation affects the phytochemical and host interaction. Future investigations must take extra caution in model selectionand result interpretation
