Nanotechnology and Nutraceuticals had gained the attention and growing interest in scientific research. Nanotechnology involves the manipulation of materials at the Nanoscale (typically at dimensions less than 100 nm) to create new properties and functionalities. On the other hand, Nutraceutics refers to the use of bioactive compounds and natural products found in food for health benefits beyond basic nutrition. The combination of these two fields, often referred to as nanonutraceuticals or nanoceuticals, explores how nanotechnology can be applied to enhance the delivery, stability, and bioavailability of bioactive compounds in food and dietary supplements. Indeed, the application of nanotechnology to nutraceuticals has the potential to revolutionize the field and address some of the limiting factors such as low water solubility, low stability and high susceptibility to light and oxygen, poor absorption and potential chemical modifications after their administration associated with traditional formulations. While the potential benefits are significant, it’s important to acknowledge challenges and considerations, including safety, regulatory approval, and ethical concerns associated with the use of nanotechnology in food and healthcare. Additionally, research is ongoing to further optimize nanonutraceutical formulations and understand their long-term effects.
