ABSTRACT
A nutraceutical is considered as a food or its part that, in addition to its normal nutritional value, provides health benefits including the prevention of disease or betterment of health. These can be considered nonspecific biological therapies not only used to promote the general well-being but also to mitigate, prevent, and treat various diseased states usually in conjunction with other therapeutic agents. If globalization of the nutraceutical and functional food industries presents significant challenges, it provides enormous opportunities for the pharmaceutical and food industries, too. However, the bioavailability of nutraceuticals has always been a vital concern. Accordingly, the present chapter throws light on various challenging issues of existing formulation with further improved possibilities via delivery using nanotechnology-enabled strategies. Nanotechnology has immense potential to improve quality of food supplements by increasing their potency, improving their stability and taste, and is thus extensively used in pharmaceuticals. Judicious application of nanotechnology in formulation and administration of nutraceuticals may help us in both attaining higher concentration and better stability. Henceforth, it is anticipated that in future after successive advancement of time and science, nutraceuticals would offer a competitive alternative to medicine.
