Background Evaluating the scientific merit of articles and advertisements about exercise and nutrition products is a key skill that all sports nutrition professionals must possess. This paper provides a definition of ergogenic aids and dietary supplements and discusses how dietary supplements are legally regulated. Other sections highlight how to evaluate the scientific merit of nutritional supplements and provide general nutritional strategies to optimize performance and enhance recovery. Finally, a brief overview of the efficacy surrounding many supplements commonly touted to promote skeletal muscle hypertrophy and improve physical performance is provided. In this respect, many supplements have had additional studies published that has led to some supplements being placed into a different category or removed from the review altogether. We understand and expect that some individuals may not agree with our interpretations of the literature or what category we have assigned a particular supplement, but it is important to appreciate that some classifications may change over time as more research becomes available. Definition of an ergogenic aid An ergogenic aid is any training technique, mechanical device, nutritional ingredient or practice, pharmacological method, or psychological technique that can improve exercise performance capacity or enhance training adaptations [ 2 — 4 ].
Although many dietary ingredients have been introduced into dietary supplements since October and have not been submitted to the FDA for a safety review, nutritional supplementation writ large is generally safe. Perhaps more alarming is a report by the Centers for Disease Control suggesting 2,, emergency room visits were due to prescription drug-related events which dwarfs the emergency room visits due to dietary supplements adjusted from 23, visits after excluding cases of older adults choking on pills, allergic reactions, unsupervised children consuming too many vitamins, and persons consuming ingredients not defined by DSHEA as a dietary supplement [ 5 ].
Notwithstanding, there have been case reports of liver and kidney toxicity potentially caused by supplements containing herbal extracts [ 7 ] as well as overdoses associated with pure caffeine anhydrous ingestion [ 8 ].
Collectively, the aforementioned statistics and case reports demonstrate that while generally safe, as with food or prescription drug consumption, dietary supplement consumption can lead to adverse events in spite of DSHEA and current FDA regulations described below. New dietary ingredients Recognizing that new and untested dietary supplement products may pose unknown health issues, DSHEA distinguishes between products containing dietary ingredients that were already on the market and products containing new dietary ingredients that were not marketed prior to the enactment of the law.
The first criterion is silent as to how and by whom presence in the food supply as food articles without chemical alteration is to be established. The second criterion—applicable only to new dietary ingredients that have not been present in the food supply—requires manufacturers and distributors of the product to take certain actions.
The guidance prompted great controversy, and FDA agreed to issue a revised draft guidance to address some of the issues raised by industry. The purpose of the Draft Guidance was to help manufacturers and distributors decide whether to submit a premarket safety notification to FDA, help prepare NDI notifications in a manner that allows FDA to review and respond more efficiently and quickly, and to improve the quality of NDI notifications.
The Draft Guidance has been criticized by industry and trade associations for its lack of clarity and other problems.
Self-Affirmed GRAS is when a company has a team of scientific experts evaluate the safety of their ingredient. There is no requirement that the safety dossier be submitted to FDA but is used by the company as an internal document that may be relied upon if the ingredient is challenged by the FDA.
In any event, the likelihood of another revised Draft Guidance from FDA becoming available in the future is high, and possibly more enforcement actions taken against companies that market an NDI without submitting a notification. Adverse event reporting In response to growing criticism of the dietary supplement industry, the th Congress passed the first mandatory Adverse Event Reporting AER legislation for the dietary supplement industry. After much debate in Congress and input from the FDA, the American Medical Association AMA , many of the major supplement trade associations, and a host of others all agreed that the legislation was necessary and the final version was approved by all.
The law strengthens the regulatory structure for dietary supplements and builds greater consumer confidence, as consumers have a right to expect that if they report a serious adverse event to a dietary supplement marketer the FDA will be advised about it.
An adverse event is any health-related event associated with the use of a dietary supplement that is adverse.
A serious adverse event is an adverse event that A results in i death, ii a life-threatening experience, iii inpatient hospitalization, iv a persistent or significant disability or incapacity, or v a congenital anomaly or birth defect; or B requires, based on reasonable medical judgment, a medical or surgical intervention to prevent an outcome described under subparagraph A.
Once it is determined that a serious adverse event has occurred, the manufacturer, packer, or distributor responsible person of a dietary supplement whose name appears on the label of the supplement shall submit to the Secretary of Health and Human Services any report received of the serious adverse event accompanied by a copy of the label on or within the retail packaging of the dietary supplement.
The responsible person has 15 business days to submit the report to FDA after being notified of the serious adverse event. Following the initial report, the responsible person must submit follow-up reports of new medical information that they receive for one-year.
Adulterated supplements The FDA has various options to protect consumers from unsafe supplements. The FDA also has the authority to protect consumers from dietary supplements that do not present an imminent hazard to the public but do present certain risks of illness or injury to consumers.
The law prohibits introducing adulterated products into interstate commerce. The standard does not require proof that consumers have actually been harmed or even that a product will harm anyone.
It was under this provision that the FDA concluded that dietary supplements containing ephedra, androstenedione, and DMAA presented an unreasonable risk. Most recently, FDA imposed an importation ban on the botanical Mitragyna speciose, better known as Kratom.
In , FDA issued Import Alert 54—15, which allows for detention without physical examination of dietary supplements and bulk dietary ingredients that are, or contain, Kratom. Criminal penalties are present for a conviction of introducing adulterated supplement products into interstate commerce.
While the harms associated with dietary supplements may pale in comparison to those linked to prescription drugs, recent pronouncements from the U.
Department of Justice confirm that the supplement industry is being watched vigilantly to protect the health and safety of the American public. However, it was not until that the cGMPs were finally approved, and not until that the cGMPs applied across the industry, to large and small companies alike. The adherence to cGMPs has helped protect against contamination issues and should serve to improve consumer confidence in dietary supplements.
The market improved as companies became compliant with cGMPs, as these regulations imposed more stringent requirements such as Vendor Certification, Document Control Procedures, and Identity Testing. These compliance criteria addressed the problems that had damaged the reputation of the industry with a focus on quality control, record keeping, and documentation.
However, it does appear that some within the industry continue to struggle with compliance.
In Fiscal Year , it was reported that approximately Further, Undoubtedly, relying on certificates of analysis from the raw materials supplier without further testing, or failing to conduct identity testing of a finished product, can result in the creation of a product that contains something it should not contain such as synthetic chemicals or even pharmaceutical drugs.
All members of the industry need to ensure compliance with cGMPs. Marketing claims According to the Nutrition Labeling and Education Act NLEA , the FDA can review and approve health claims claims describing the relationship between a food substance and a reduced risk of a disease or health-related condition for dietary ingredients and foods.
However, since the law was passed it has only approved a few claims. The delay in reviewing health claims of dietary supplement ingredients resulted in a lawsuit, Pearson v. Shalala, filed in Community Reviews. Showing Rating details. Sort order.
