Supplementation refers to the process of providing additional nutrients or substances to a person's diet in order to enhance their overall health and well-being. This can include vitamins, minerals, amino acids, herbs, and other natural ingredients that are believed to have positive effects on the body when taken in addition to regular food intake. Supplementation is often used to address nutritional deficiencies or to support specific health conditions, but it can also be used by individuals who want to improve their overall health and performance through targeted nutrient intake.
