Which agency is responsible for regulating the safety of dietary supplements?

The Food and Drug Administration (FDA) is the agency tasked with regulating the safety of dietary supplements. This responsibility includes overseeing the manufacturing, labeling, and marketing of these products to ensure they meet safety standards. The FDA requires that dietary supplements are safe for consumption and that any health claims on labels are substantiated.

In contrast, the Department of Agriculture primarily focuses on the agricultural aspects of food safety and the promotion of agricultural products rather than the regulation of dietary supplements. The Centers for Disease Control and Prevention (CDC) is more concentrated on public health and disease prevention, while the National Institutes of Health (NIH) is primarily involved in biomedical research and does not directly regulate dietary supplements. Thus, the FDA plays a critical role in ensuring that dietary supplements are safe for consumers.
