What Should Dietary Supplement Oversight Look Like in the US?

Abstract

Most American adults who use dietary supplements (eg, vitamins, minerals, plant and animal extracts, hormones, and amino acids) ingest them orally. The market for these products has grown rapidly and significantly over the last 25 years, but consumer protection regulations have not kept pace. In the United States, supplements' safety is regulated by the US Food and Drug Administration (FDA), but statutory limitations prevent the FDA from effectively regulating these products, exacerbate public health risk, and have generated numerous calls for reform. This article considers key features of reforms likely to strengthen the FDA's capacity to promote safety and consumer protection.
