What Is a Nutraceutical?


Updated February 05, 2013

Question: What Is a Nutraceutical?
Many products are marketed as being beneficial for arthritis and joint health. Some are dietary supplements while others are classified as functional foods (a food product consumed as part of the daily diet that may offer benefit beyond nutrition) or nutraceuticals. Unlike prescription medications, dietary supplements, and functional foods, nutraceuticals are not regulated by the U.S. Food and Drug Administration.

What is a nutraceutical? What is the difference between a nutraceutical and dietary supplement?


A nutraceutical is a food or food component that claims to have health benefits, including treatment and prevention of disease. In 1989, Stephen DeFelice, M.D., derived the term "nutraceutical" from "nutrition" and "pharmaceutical." Basically, it's used as a marketing term.

What Is a Dietary Supplement?

Glucosamine, chondroitin and MSM, are popular dietary supplements that are touted as beneficial for joint health.

As defined by Congress in the Dietary Supplement Health and Education Act, which became law in 1994, a dietary supplement is a product (other than tobacco) that is intended to supplement the diet; contains one or more dietary ingredients (vitamins, minerals, herbs, amino acids, and other substances); is intended to be taken orally; and is labeled on the front panel as being a dietary supplement.

How Do Nutraceuticals Differ From Dietary Supplements?

Nutraceuticals do more than just supplement the diet. They, as was pointed out, help with disease prevention and treatment. Theoretically, the appeal of nutraceuticals has to do with accomplishing treatment goals without side effects.

Using glucosamine as an example, by promoting joint health, it would seem by definition that it is more of a nutraceutical than dietary supplement. Are we essentially splitting hairs over terminology? Apparently so.

According to Arthritis Research and Therapy, "the term nutraceutical has no regulatory definition and is not recognised by the U.S. Food and Drug Administration, which uses instead the term "dietary supplements." Some functional ingredients are sold as nutraceuticals in some countries but as drugs (that is, requiring medical prescription) in others."

Bottom Line

As a consumer, here's what you need to know: In the United States, you will, more often than not, see reference to dietary supplements. That term is essentially interchangeable with the term nutraceutical.

Always consult with your doctor before trying any dietary supplement/nutraceutical.
