The Food and Drug Administration is in charge of regulating pharmaceuticals and dietary supplements. There is a significant difference between medicinal foods and dietary supplements. Dietary foods are nutritious foods that are promoted locally, whereas medicinal foods are produced by medical supplement companies. They are sometimes confused with dietary supplements because they both contain nutritional elements. Dietary supplements and functional foods are intended to meet the nutritional needs of healthy people, whereas medical foods are intended to support the nutritional treatment of specific conditions and are administered under the physician’s supervision.
