supplements are commonly used to support overall health and address nutritional deficiencies. They may contain vitamins, minerals, herbal extracts, or other bioactive compounds that contribute to improved energy levels, immune function, or general well-being. When used appropriately, supplements can be beneficial, especially for individuals with increased nutritional needs or limited dietary intake. However, supplements should not replace a balanced diet, and excessive or unsupervised use may lead to adverse effects or interactions with medications. Therefore, it is important to use supplements responsibly and seek professional advice when necessary.
