Reporting Randomized Trials on Dietary Supplements law in Virginia

The aim of the study was to investigate motivations for using supplements, characterize types of products used by the most frequently reported motivations, and explore the role of physicians and healthcare practitioners in guiding choices regarding supplements. Americans spent over $30 billion on dietary supplements in 2011. Our findings suggest that adults frequently reported using supplements for the purposes of improving or maintaining health; however, most products were used because of personal choice (77%), not because of the recommendation of a health care professional (23%).

Previous studies have also shown that supplement users had higher amounts of most vitamins and minerals than nonusers due solely to food choices. Thus, disentangling the effects of healthful dietary choices and lifestyle choices from supplement use is generally challenging in epidemiologic studies. Randomized controlled trials are ideal for investigating supplement use and health outcomes, yet often yield inconsistent results. Randomized controlled trials are ideal for investigating the effects of dietary supplement use. For example, more than 80 percent of children aged 1 to 3 years taking dietary supplements consumed levels above the upper limits of vitamin A and niacin intakes. In the United States, excessive intakes were noted for vitamin A (97 percent) and zinc (68 percent) among children given dietary supplements. High-quality evidence is lacking for long-term negative effects of supplementation. For example, in a Canadian national survey, over 80 % of children aged 1-3 years who took dietary supplements consumed vitamin A and niacin at levels above the upper limit. In the US, excessive intake was noted for vitamin A (97 %) and zinc (68 %) among toddlers who were given supplements. High quality evidence is lacking on the long term adverse effects of excess intake for several nutrients so it is unclear whether this is a cause for concern. With the recent rise of people reporting following restrictive diet patterns, such as the ketogenic, paleolithic, vegan, and vegetarian diets, supplementation is needed for assessing the effectiveness of supplementation in meeting the needs of this particular population. Case reports may also provide insights that might be missed or overlooked by randomized controlled trials. Quiz Ref ID The National Institutes of Healths Office of Dietary Supplements now produces fact sheets about dietary supplements and distributes information on cases and smaller studies. When data from large-scale clinical trial data are lacking, there is potential for supplementation.

Cases can also provide insights that might be lost or overlooked in randomized controlled trials. Quiz Ref IDThe Office of Dietary Supplements at the National Institutes of Health currently compiles fact sheets on dietary supplements and disseminates information about cases and small studies. When large-scale clinical trial data are lacking, it is still possible to evaluate a supplement. The rareness of breakthrough discoveries deters manufacturers from conducting studies, and certain dietary supplement ingredient research is restricted to case reports or small clinical studies, usually conducted by an independent research team that has little or no funding. Under existing U.S. Food and Drug Administration (FDA) regulations, manufacturers are not required to provide the FDA evidence for dietary supplements safety and effectiveness in treating any disorder, as is required of pharmaceuticals. Under DSHEA, supplement manufacturers are not required to prove safety or effectiveness; Rather, DSHEA deliberately minimizes the supervision by the US FDA, focusing on the value the industry provides to the U.S. economy. Under the DSHEA, FDA has the burden to demonstrate that a specific food additive is unsafe to consume by consumers before it may be taken off the market.

Unlike with medication regulations, the Food and Drug Administration cannot force manufacturers of dietary supplements to report adverse events. Further, manufacturers are not required to submit product safety data to FDA prior to marketing of a dietary supplement, except when that supplement contains a novel dietary ingredient (a dietary ingredient not sold in this country before Oct. 15, 1994) that has not been presented in the food supply as a food-use article in a form where food has not been chemically altered. The basic structure of DSHEA allowed all products marketed as dietary supplements at the time the Act was enacted to remain on the market unless the Food and Drug Administration could show safety problems with a particular product or line of products — this is the so-called grandfather provision; manufacturers must notify the FDA before any new ingredients are marketed. Consumers also misunderstanding the Food and Drug Administrations role in regulating dietary supplements, with 33% believing DSHEAs disclaimer meant the product was unapproved or unregulated by FDA.

The authors found no impact of presence or absence of disclaimers on consumers beliefs about whether a product will have the effects claimed, or their belief that the Food and Drug Administration evaluated a manufacturers claims about efficacy–despite the fact that the DSHEA disclaimer explicitly states that FDA does not review claims. The other scientific evidence disclaimer did not affect consumers beliefs in the link between supplements and treating diseases either (p>0.30). The authors concluded that disclaimers, which are common on supplements, did not significantly decrease consumers misconceptions of the Food and Drug Administrations role in the approval of supplements. The aforementioned five randomized studies were conducted of consumers perceptions of safety and effectiveness of different food additives when the disclaimer DSHSEA was present (Exhibit 1). The existing regulations that regulate dietary supplements are being scrutinized more and more, with justification given widespread dietary supplement use in more than one-half of the U.S. population, and highly publicized concerns about safety [e.g., Ephedra, Hydroxycut (Iovate Health Sciences International, Inc.), and 1,3-dimethylamylamine (DMAA) in the last 20 years. The current statutes governing regulation of dietary supplements have been increasingly and reasonably scrutinized, given the widespread use of dietary supplements by over one-half of the US population, as well as highly publicized safety concerns [e.g., ephedra, Hydroxycut (Iovate Health Sciences International, Inc. ), and 1,3-dimethylamylamine (DMAA)] over the past 20 y.o., it is my view that supplements are inadequately regulated in the US; nevertheless, such products should remain regulated as subcategories of traditional foods, with a view to maintaining compliance with the scores of other influential laws and regulations that apply specifically to specific products and/or ingredients. For example, regulations that apply specifically to domestic seafood products, fish products etc., and are appropriately subject to regulatory oversight. These products must remain subject to the regulations governing dietary supplements. However, these products must remain subject to regulation.
