The market for dietary supplements in the United States is growing rapidly, with consumers spending over $48 billion in 2021 and projected to grow 5% annually. At least half of U.S. adults take dietary supplements. Despite enthusiasm, experts worry about adverse effects and lack of evidence for many supplements. However, supplements like prenatal folic acid have strong evidence of benefit. Additional oversight may be needed to ensure supplement safety, and a bipartisan bill was introduced in the Senate for this purpose. Consumers can ensure supplement safety by consulting with their doctors, looking for inspected labels, and reporting problems to the FDA.
