Nutritional supplementation refers to the use of products, such as vitamins, minerals, herbs, or amino acids, to enhance dietary intake. These supplements can help fill nutritional gaps in a person's diet, support overall health, and address specific health concerns. They come in various forms, including tablets, capsules, powders, and liquids. Many people use nutritional supplements to boost their energy levels, improve immune function, or support muscle recovery after exercise. However, it's important to consult with a healthcare professional before starting any supplementation, as excessive intake can lead to adverse effects or interact with medications.
