Health Supplements: The “Wild West” of FDA Regulations

Gabe Branco, MJLST Staffer 

At some point, we all have taken a multivitamin and/or some type of dietary supplement. They are hard to miss in most stores such as Target or Wal-Mart.  The bright colored packaging and unfulfilling promises of “losing weight quickly” without dieting or “building muscle” without working out catches everybody’s attention. Most people assume that these products, ironically labeled “health” or “dietary” supplements, must be safe to ingest due to placing them in the same category as a “drug,” or because they deem the supplement to be “natural.” However, the reason people are mistaken is because the Food and Drug Administration (“FDA”) chooses to differentiate “health” products from “drugs.”

Under the FDA’s current regulatory scheme, “health” supplements are treated more like special foods than drugs. Drugs are considered unsafe until proven safe through clinical trials. These trials must be done on all drugs, even those that are sold without a required prescription. The trials must show that the drug is both safe and effective for the specified use. Once the drug is approved, manufacturers are subject to carefully monitored conditions and packaging requirements. The packaging requirement includes conditions the drug has been proven to treat, known side effects, contraindications, and unsafe interactions with other drugs. After the drug has been manufactured and released to the public for consumption, the FDA follows up on any adverse effects consumers and their doctors report, along with any adverse effects reported by the manufacturer.

“Dietary” supplements, on the other hand, are seen as safe until proven unsafe, a stark contrast to their drug counterpart. The Dietary Supplement Health and Education Act (DSHEA) defines “dietary” supplements as a category of food. As such, “dietary” supplements do not undergo the rigorous pre-manufacturing and post-manufacturing approval and monitoring process that drugs do. DSHEA prohibits supplements from containing anything that may have “a significant or unreasonable risk of illness or injury” when the supplement is used as directed on the label, or with regular use if there are no directions. While the regulation makes clear these supplements should not significantly or unreasonably expose the public to increased risk of harm, DSHEA fails to enforce the regulation with any preventative measures.

DSHEA effectively allows manufacturers to print any statement they wish on “dietary” supplement labels, so long as it is followed by the phrase “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. This practice is troublesome because the statement may suggest or claim outright that the “dietary” supplement treats symptoms or results in an outlandish outcome if taken. Even with the FDA warning, consumers would have little to no reason to assume that supplements placed on shelves everywhere could contain none of the listed ingredients or unknown ingredients that can cause adverse health effects.

The FDA has the authority to stop any production of “dietary” supplement if it is shown there is an increased risk of harm to the public. However, this only occurs after the release of the supplement and subsequent adverse effects impact consumers. Due to the lack of pre-manufacturing testing requirements, many “dietary” supplements contain germs, pesticides, or toxic heavy metals that may adversely impact consumers. In addition, many “dietary” supplements either do not contain what is listed on the label, contain more or less of what is listed on the label, or even contain ingredients not listed on the label. This issue could also stem from parties other than the manufacturers and sellers. Without any regulations pre-manufacturing, many suppliers of ingredients may mix or substitute the ingredients sold to manufacturers with less expensive or tainted filler ingredients.

These issues become problematic when an ingredient the FDA would deem a “drug” finds its way into a “dietary supplement.” Many male enhancers or muscle building “dietary” supplements have been found to contain substances much like Viagra or Cialis, which are regulated as “drugs.” In addition, certain weight loss supplements have been found to contain sibutraimine, which has been banned in the United States. All of these supplements were recalled by the FDA in a reactionary manner. However, in most instances a “dietary” supplement may contain a drug that has little to no known effects. Having little to no known effects makes it more difficult to detect if a “dietary” supplement indeed contains a drug, and if it then must undergo the more rigorous FDA drug requirements. By providing manufacturers and sellers a pathway to produce categorical “drugs” and distribute them to the public without undergoing the rigorous FDA drug testing processes, DSHEA potentially does more deregulation than regulation.

FDA regulations concerning “dietary” supplements should be as stringent as regulations governing drugs. The simplest solution would be to implement the same pre-manufacturing and post-manufacturing procedures that are required of “drug” manufacturers into the “dietary” supplement realm. Doing so would fulfill DSHEA’s requirement that the “dietary” supplements do not cause a significant or unreasonable increase in risk of injury or illness. Additionally, this would allow the FDA to regulate “drugs” to its fullest potential.
