Nutraceutical regulation, Dietary supplements at FDA, Supplements adverse events
Background: The Food and Drug Administration (FDA) originated from the passage of the 1906 Pure Food and Drugs act aimed to rein in the long-standing abuse in the consumer product marketplace. The act was passed to prohibit interstate commerce of misbranded and adulterated foods, drinks, drugs. Thus, promoting the FDA’s mission to protect the public health by regulating human and veterinary drugs, biological products, medical devices, food supply, cosmetics, and tobacco to ensure safety, efficacy, and security. Progressing further in 1994, the Dietary Supplement Health and Education Act (DSHEA) was established designating specific label requirements, providing regulatory framework, and authorizing the FDA to promulgate good manufacturing practices for dietary supplements. This act defined and classified “dietary supplements” and “dietary ingredients” as food requiring all over the counter products (OTC) products to consist of labeling that is easy to understand and meets the FDA quality, effectiveness, and safety standards. However, under the umbrella of OTC products, the FDA fell short in its regulation of the expansive dietary supplement market. The objective of this study is to discern how the lack of efficacy in the FDA's regulations of OTC dietary supplements inevitably inspired more harm than benefit.
Methods: This review comprised of case studies including young adolescents and adult consumers who experienced adverse events from the use of dietary supplements. Products which showed highest prevalence in adverse event reports through the Food and Drug Administration CFSAN Adverse Event Reporting System (CAERS) included but not limited to; Vitamin E (vitamin derivative), Beta-sitosterol (plant sterol) Yohimbine, Kava Kava Kratom, Garcinia Cambogia, (herbal products) and OxyElite Pro (marketed weight loss product). The primary endpoint was evaluating the FDA’s regulations on dietary supplement safety protocols. The secondary endpoint was assessing the actions of the FDA in response to these case events.
Results: Overall, between 2004 to 2021, a total of 79,071 adverse events related to the use of dietary supplements were reported to the Center for Food Safety and Applied Nutrition. Vitamin E products for example, marketed for decades for their antioxidant benefits in turn have shown significant evidence of toxicity and an increased risk of bleeding outweighing its potential benefit. The FDA’s response was simply implementing a label guideline update, yet this update had evidence of minimal effect as the number of cases gradually continued to increase. Likewise, herbal products such as Kava Kava, Yohimbine, Kratom, and Garcinia Cambogia, in addition to weight regulating products, such as OxyElite Pro and HydroxyCut, have been linked to organ failure, hepatic, renal, cardiac toxicity, and death respectively. The FDA merely responded through instating public consumer warnings of their effects with consumption and limited recalls of certain products.
Conclusion: With the easy accessibility of these products, the general public is more inclined to its use without proper guidance and monitoring from their healthcare team, posing as a major concern for possible interactions, contraindications and unfavorable outcomes. With proper implementation of stringent regulations post findings from increased studies on efficacy and safety, cases of adverse events could have been reduced significantly or averted completely. The FDA’s minimalistic efforts consisting of only post-marketing monitoring and retrospective actions of label modifying have time and time again shown flaws as seen in the growing series of reports. By emending the over-the-counter supplement review process to reflect that of prescription medication, the magnitude of adverse events can be diminished. The process should include preclinical research in addition to clinical research, FDA thorough examination of data prior approval and post marketing surveillance.
