ABSTRACT
Nutraceuticals—bioactive compounds derived from food sources with demonstrated health benefits—represent a paradigm shift in preventive healthcare. This comprehensive review synthesizes current evidence on nutraceutical applications across chronic disease prevention, examining their mechanisms, efficacy, safety, and regulatory landscapes. Analysis of >150 studies reveals that targeted nutraceutical interventions can reduce cancer incidence by up to 35%, improve cardiovascular outcomes by 25-40%, and enhance glycemic control in diabetes. Key mechanisms include oxidative stress reduction, inflammation modulation, and gut microbiome optimization. Despite promising results, challenges persist in standardization, bioavailability, and regulatory harmonization. This review provides evidence-based guidance for healthcare professionals and identifies critical research priorities for integrating nutraceuticals into mainstream preventive medicine.
