• Source: Nutraceutical

Nutraceutical is a marketing term used to imply a pharmaceutical effect from a compound or food product that has not been scientifically confirmed or approved to have clinical benefits. In the United States, nutraceuticals are considered and regulated as a subset of foods (such as dietary supplements) by the Food and Drug Administration (FDA).
There are no internationally defined properties of nutraceuticals. Due to the vague, undiscriminating evidence for the biological effects of nutraceutical products, experts have proposed abandoning the term. The word "nutraceutical" is a portmanteau, blending the words "nutrition" and "pharmaceutical."




Regulation


Nutraceuticals are treated differently in different jurisdictions.




= Canada

=
Under Canadian law, a nutraceutical can be marketed as either a food or a drug; the terms "nutraceutical" and "functional food" have no legal distinction, as both refer to "a product isolated or purified from foods that is generally sold in medicinal forms not usually associated with food [and] is demonstrated to have a physiological benefit or provide protection against chronic disease."




= United States

=
The term "nutraceutical" is not defined by the FDA. Depending on its ingredients and the claims with which it is marketed, a product is regulated as a drug, dietary supplement, food ingredient, or food.




= Other sources

=
In the global market, there are significant product quality issues. Nutraceuticals from the international market may claim to use organic or exotic ingredients, yet the lack of regulation may compromise the safety and effectiveness of products. Companies looking to create a wide profit margin may create unregulated products overseas with low-quality or ineffective ingredients.




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

=

In the United States, the Dietary Supplement Health and Education Act (DSHEA) of 1994 defined the term "dietary supplement": "A dietary supplement is a product taken by mouth that contains a 'dietary ingredient' intended to supplement the diet. The 'dietary ingredients' in these products may include: vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, glandulars, and metabolites. Dietary supplements can also be extracts or concentrates, and may be found in many forms such as tablets, capsules, softgels, gelcaps, liquids, or powders."
Dietary supplements do not have to be approved by the FDA before marketing, but companies must register their manufacturing facilities with the FDA and follow current good manufacturing practices (cGMPs). With a few well-defined exceptions, dietary supplements may only be marketed to support the structure or function of the body, and may not claim to treat a disease or condition, and must include a label that says: “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” The exceptions are when the FDA has reviewed and approved a health claim. In those situations the FDA also stipulates the exact wording allowed.




= Functional foods

=

Functional foods are fortified or enriched during processing and then marketed as providing some benefit to consumers. Sometimes, additional complementary nutrients are added, such as vitamin D to milk.
Health Canada defines functional foods as "ordinary food that has components or ingredients added to give it a specific medical or physiological benefit, other than a purely nutritional effect." In Japan, all functional foods must meet three established requirements: foods should be (1) present in their naturally occurring form, rather than a capsule, tablet, or powder; (2) consumed in the diet as often as daily; and (3) should regulate a biological process in hopes of preventing or controlling disease.




Possible clinical application


Nutraceuticals have been considered as possible adjuncts to therapies for clinical disorders.




Market


The modern nutraceutical market developed in Japan during the 1980s. In contrast to the natural herbs and spices used as folk medicine for centuries throughout Asia, the nutraceutical industry grew alongside the expansion of modern technology in the early 21st century.
The market for nutraceuticals is projected to grow to about 614 billion euros (approx. US$675 billion; 2023) by the year 2027.




Etymology


The word "nutraceutical" is a portmanteau of the words "nutrition" and "pharmaceutical", coined in 1989 by Stephen L. DeFelice.




Criticism


Because nutraceuticals are unregulated, these supplements are sold by marketing hype rather than being based on actual clinical evidence. There is no compelling evidence for efficacy in nutraceuticals. After scientists disputed the benefits of nutraceuticals, such as probiotics in yogurt, Danone was forced to pay a large financial penalty for falsely claiming its products Actimel and Activia boosted the immune system.
