ABSTRACT

Nutraceuticals, a word established by Stephen De Felice in 1989, represent the intersection of nutrition and medicines, providing health advantages beyond basic nutrition, such as illness prevention and treatment. In this study, the roles of nutraceuticals are examined in three important populations: athletics, geriatrics, and pediatrics. Nutraceuticals such as omega-3 fatty acids, probiotics, vitamin D, iron, multivitamins, and prebiotics have important roles in pediatric development, cognitive function, and immunological health. Nutraceuticals such as antioxidants, plant polyphenols, calcium, vitamin D, prebiotics, probiotics, and whey protein are critical for the elderly in fighting the effects of aging, maintaining bone and muscle function, and improving gut health. Among athletes, nutraceuticals like whey proteins, branched-chain amino acids (BCAAs), essential fats, vitamins, minerals, glutamine, and creatine play a pivotal role in enhancing performance, accelerating recovery, and maintaining muscle mass. This review underscores the growing importance of nutraceuticals in promoting health and preventing diseases, driven by increasing consumer awareness and scientific advancements. The findings highlight the potential of nutraceuticals to address specific nutritional needs across different life stages, contributing to overall health and well-being.
