The FDA is the agency that regulates tobacco, dietary supplements, vaccines, and other products to safeguard public health in the U.S. It ensures product safety, efficacy, and truthful labeling, working with other agencies for comprehensive oversight.
Step-by-step explanation:
The Food and Drug Administration (FDA) is the federal agency responsible for regulating a broad range of products in the United States. It plays a crucial role in overseeing the safety and efficacy of items such as tobacco, dietary supplements, vaccines, veterinary drugs, medical devices, cosmetics, products that emit radiation, and biological products. The FDA operates under the authority of the Federal Food, Drug, and Cosmetic Act, among other laws, to protect public health by ensuring that the above-mentioned products are safe for consumption and use.
Working alongside other federal and local agencies, the FDA also regulates food safety and monitors claims made in the labeling of food and dietary supplements. The agency's regulatory scope is significant, overseeing consumer goods that constitute a substantial portion of consumer expenditures in the United States and includes products that come through international imports. Regulatory programs under the FDA cover various aspects of product safety, labeling, marketing, and distribution, aiming to provide the public with accurate, science-based information to enhance health and wellness.
