The term "Nutraceutical" is a combination of "Nutrition" and "Pharmaceutical." Nutraceuticals, broadly speaking, are foods or components of foods that significantly alter and maintain the normal physiological function that supports healthy human beings. The Foundation for Innovation in Medicine (New York, US) first used the term "nutraceutical" in 1989 to describe this quickly expanding field of biomedical research. Dietary fiber, prebiotics, probiotics, polyunsaturated fatty acids, antioxidants, and other diverse kinds of herbal/natural foods are some of the food products used as nutraceuticals. Risk of drug toxicity or side effects prompted us to seek functional food-based and safer nutraceutical alternatives for the management of health. Overall, the term "nutraceutical" has ushered in a new era of medicine and health, one in which the food industry has evolved into a research-focused enterprise. The goal of the current review is an overview of nutraceuticals and also their comparison with Pharmaceuticals.
