Nutritional supplements are products designed to enhance the diet by providing additional nutrients that may be missing or insufficient in a person's daily intake. These can include vitamins, minerals, amino acids, and herbal extracts. They come in various forms, such as tablets, capsules, powders, and liquids, and are often used to support overall health, boost energy, or address specific health concerns. While many people use nutritional supplements to improve their well-being, it's important to consult with a healthcare professional before starting any new supplement regimen. Overuse or misuse of supplements can lead to adverse effects, and they should not replace a balanced diet rich in whole foods like fruits, vegetables, and grains.
