A dietary supplement is a product designed to enhance the diet by providing additional nutrients, such as vitamins, minerals, herbs, amino acids, or other substances. These supplements come in various forms, including tablets, capsules, powders, and liquids. They are intended to support overall health and well-being but are not meant to replace a balanced diet. Dietary supplements are regulated by the U.S. Food and Drug Administration (FDA) but do not require the same rigorous testing as prescription medications. It is important for consumers to consult with healthcare professionals before starting any supplement to ensure safety and effectiveness, especially if they have existing health conditions or are taking other medications.
