Therapeutic Implications of Nutraceutical Nanotechnology for the Treatment of Chronic Diseases.

Nanotechnology possesses therapeutic value in managing chronic disease, but it has limitations like as solubility, stability, and targeted delivery in clinical applications. The review explores how nanotechnology-based delivery systems improve the efficacy, bioavailability, and targeted actions of nutraceutical compounds. Health benefits, sustainable nanotechnology, market size, and growth forecasts have shown positive results in this industry over the last two decades. The disease-like respiratory, diabetes, Alzheimer's and Parkinson's, and breast cancer top focused sectors for this nutraceuticals sector. Most literature has been collected from 2020-2025 using PubMed, Scopus, Google Scholar, and Web of Science. The different criteria included preclinical, clinical, and nanotechnology-integrated nutraceutical studies. The liposomes, dendrimers, nanoemulsions, and polymeric nanoparticles significantly enhance the stability and delivery of key bioactive as example like curcumin, resveratrol, and omega-3. Early-stage clinical trials show promise for diseases like Alzheimer's, diabetes, and cancer. Nanotechnology is the reshaping of nutraceutical therapy, through regulatory, toxicology, and large-scale validation gaps persist. Future work must focus on green synthesis, long-term safety, and harmonized approval pathways. Despite this, the industry still needs collaboration between academic researchers, scientists, and regulatory bodies to start the next generation of clinical trials and treatments that can reduce the risk of diseases and death in the future.
