ABSTRACT
This contribution comprehensively summarizes the nanotechnological breakthrough in the area of scientific inventions by means of extremely small particle dimension, thereby imparting novel properties and increasing efficacy of the material. These contemporary qualities of nanotechnology are extended in the escalating field of nutraceuticals to conquer the restrictions posed by inherent complex nature of bioactives and to elevate pharmacokinetic and pharmacodynamic potential, hence, boosting their bioavailability. Nanonutraceuticals is rapidly burgeoning field encompassing health benefits, wellness and preventive healthcare approach. Nanodelivery systems for traditional nutraceuticals have shown improved efficacy, maintaining good health as well as in the management of many diseases like Alzheimer’s, cardiovascular disease, cancer, arthritis. Novel nanocarriers like nanoparticles, solid lipid nanoparticles, niosomes, nanoemulsions, nanotubes, phytosomes exhibit advantages of increased permeability and absorption, high bioavailability, controlled and site specific targeted release, and improved physical stability. However, assured human and environmental risk assessment and balanced regulatory guidelines for nanonutraceuticals is the need of an hour for a safe future.
