what does the FDA do

The FDA (Food and Drug Administration) is a federal agency in the United States responsible for protecting and promoting public health through the regulation and supervision of food safety, dietary supplements, prescription and over-the-counter medications, vaccines, biopharmaceuticals, medical devices, blood transfusions, radiation-emitting devices, veterinary products, and cosmetics. The FDA ensures that these products are safe, effective, and accurately labeled before they are marketed to the public. Additionally, the FDA also monitors and investigates any reports of adverse reactions or safety concerns related to these products.
