Generic Name: multivitamins

Brand Names: Folgard, Natalins Rx, Nestabs CBF, Nestabs FA

Drug Class: Vitamins, Combos

What are multivitamins, and what are they used for?

Multivitamins are a combination of vitamins, minerals and other nutrients, each of which plays different roles in maintaining good health and normal functioning of the body. Multivitamins are available in many different combinations, but the most common are once-daily products that contain all or most vitamins and minerals in amounts close to daily recommended doses.

Multivitamins are used to supplement nutritional deficiency in people who are unable to get their nutrients from dietary intake alone. Multivitamins can provide the necessary nutrients to people who are on low-calorie diets, have a poor appetite, or avoid certain foods. Multivitamins may also be intravenously administered along with other nutrients to people who, for any reason, cannot use their digestive tract for nutrition and are on total IV (parenteral) nutritional support.

A lot of people take multivitamins for general health and to protect from developing chronic diseases, particularly age-related conditions, however, the benefits of multivitamins in these uses are difficult to determine. Essential nutrients are best absorbed from dietary intake for people who have no special need for supplementation.
