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 recognized 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.”
