With the authority of the FDA limited by statute to removing supplements from the market only after reports of adverse effects, the role of pharmacists to intervene and assist patients with optimal product selection is vital.

The production and distribution of dietary supplements is an industry that has grown steadily. Yet, the oversight has remained almost the same since 1994. With the authority of the FDA limited by statute to removing supplements from the market only after reports of adverse effects, the role of pharmacists to intervene and assist patients with optimal product selection is vital.

The principal legislation covering products in this classification is the Dietary Supplement Health and Education Act of 1994 (DSHEA), which defined what constitutes a dietary supplement and outlines the limited role of the FDA in the oversight of the industry. Any dietary supplement ingredients marketed before 1994 are not required to have FDA clearance before marketing in interstate commerce.1 As a result, manufacturers are responsible for ensuring that products are neither adulterated nor misbranded and comply with the Current Good Manufacturing Practices (CGMP).2 The FDA’s authority is limited to surveillance and acting after defective products reach the market. An improvement to the legislation, the Dietary Supplement and Nonprescription Drug Consumer Protection Act of 2006, was passed 12 years ago, mandating that manufacturers report adverse effects within 15 days after they are received.3

Although the DSHEA has been around for more than 20 years, the public has misconceptions about what it entails. This has a lot to do with the growth and prevalence of the supplement industry, which is projected to grow from $100 billion in 2013 to more than $260 billion by 2024.4 The appearance of supplement packaging and “dosage forms” frequently resemble those of the medications that have been proved effective and safe. Additionally, the supplements are located near these medications in stores, which may contribute to assumptions and misunderstandings about their quality. Many consumers do not know that a way to ensure that a product contains what it says and nothing more is to look for a verification seal from a quality assurance program, such as, the National Sanitation Foundation International, and the US Pharmacopeial Dietary Supplement Verification Program. Products with these seals should be recommended to patients.

In addition to misconceptions about the products’ quality, there are also misconceptions about their effectiveness and indication. This is largely related to the marketing claims put forth by the manufacturing companies. A recent example of the FDA’s postmarketing surveillance efforts comes from a Colorado manufacturer that was accused by the FDA of marketing products as drugs without the agency’s approval and committing violations of the CGMP. The company claimed that the dietary products could help treat or prevent diseases such as “heart disease, diabetes, depression, hypertension, osteoporosis, and liver and kidney disorders.” In response to the FDA’s actions, the US District Court for the District of Colorado has entered a permanent injunction against EonNutra LLC and 2 related companies, CDSM LLC and HABW LLC, as well as their owner. The manufacturer agreed to cease operations in March 2017, but this came after the FDA had inspected the business 4 times since 2012 to gather evidence and determine whether products were misbranded. The alleged misbranding was related to not only health claims. The manufacturer also “failed to list each ingredient contained in the dietary supplements.”5,6

Because of the legislative constraints on the FDA, consumers’ misconceptions, and the proximity to the patient, pharmacists need to triage existing and potential consumers. Making consumers aware of this issue can help cut down on preventable ailments resulting from the misuse of a dietary supplement or the use of defective products. Pharmacists’ knowledge of how medications, vitamins, and minerals affect the body, along with their ease of access to patients, makes them the ideal health care professionals to work collaboratively to ensure optimal outcomes of dietary supplement usage.
