Emerging Nano-Formulation Strategies for Nutraceutical Delivery

The global increase in consumer awareness of the benefits of natural ingredients has led to a paradigm shift in the health industry, with a focus on developing nutraceutical products. However, nutraceuticals often have poor oral bioavailability and stability, due to their poor solubility, chemical instability, and lower absorption, metabolism, and permeability. Nanotechnology has been used to address these challenges, with the development of various nano-technological approaches such as nanosponges, dendrimers, nanosuspensions, nanoemulsions, liposomes, nanohydrogels, carbon nanotubes, and solid lipid nanocarriers. These nanocarriers can protect nutraceuticals from harsh processing conditions, improve their solubility, and target them to specific tissues or cells. While nanotechnological approaches have the potential to improve the bioavailability and stability of nutraceuticals, more research is needed to assess their safety, efficacy, and regulatory acceptance.
