Dietary supplements are products designed to provide essential nutrients that may be missing or insufficient in a regular diet. They come in various forms, such as capsules, tablets, powders, or liquids, and include vitamins, minerals, amino acids, and herbal extracts. Dietary supplements can support overall health, enhance energy levels, boost the immune system, and address specific health concerns. While they are beneficial in filling nutritional gaps, it is important to use them responsibly and consult with a healthcare provider to ensure they align with individual health needs and goals.
