The nanotechnology is nowadays used for delivery of vitamins in an appropriate manner. Several approaches are now used for formulating a delivery system of nutraceuticals that can encapsulate various nanoformulations like nanoparticles, nanocrystals, nanocapsules, micelles, etc. Nutraceuticals come in the category of nutritional ingredients, that have the capability of delivering therapeutic or physiological benefits apart from nutritional requirements. This chapter briefly covers the vitamin and vitamins reported as nutraceuticals, vitamin-loaded nanocarrier system their preparation and characterization along with regulatory issues and role of vitamin-loaded nutraceutical in healthcare system.
