The term nutraceuticals are used to describe any product which has extra health benefits besides the essential nutritional value found in food products. These products are derived from the food sources and are said to be pharmaceutical alternatives that have physiological benefits. These include dietary supplements and functional foods.
Dietary supplements can be found in tablets, capsules, soft gels, liquids, or powders. Functional foods are the foods in which complementary nutrients and vitamins are added to food products to enhance their nutritional value.
These supplements are majorly taken to enhance digestive health, immunity, joint health, eye health, bone health, heart health, brain health, and sometimes for cosmetic purposes such as weight reduction.
