Nutraceutical, a portmanteau of the words “nutrition”?and “pharmaceutical”, was coined in 1989 by Stephen L. DeFelice, founder and chairman of the Foundation of Innovation Medicine.

Classification of nutraceuticals
Nutraceuticals are products derived from food sources that are purported to provide extra
health benefits, in addition to the basic nutritional value found in foods. Depending on the jurisdiction, products may claim to prevent chronic diseases, improve health, delay the aging process, increase life expectancy, or support the structure or function of the body.

Dietary supplements
A dietary supplement is a product that contains nutrients derived from food products that are concentrated in liquid orcapsule form.

Functional foods are designed to allow consumers to eat enriched foods close to their natural state, rather than by taking dietary supplements manufactured in liquid or capsule form. Functional foods have been either enriched or fortified, a process called nutrification. This practice restores the nutrient content in a food back to similar levels from before the food was processed. Sometimes, additional complementary nutrients are added, such asvitamin D to milk
