Which of the following statements accurately describes supplementation?

The statement that accurately describes supplementation is that a supplement is designed to supplement a diet. This means that supplements are intended to provide nutrients that may be lacking in a person's food intake, to enhance overall nutrition, or to support specific health goals. They can include vitamins, minerals, herbs, amino acids, and other substances that can contribute to better health and performance when used appropriately alongside a balanced diet.

Understanding this definition is crucial, as it highlights the role of supplements in filling dietary gaps rather than serving as a primary source of nutrition. A well-rounded diet should always be the foundation of nutrient intake, while supplements can play an important supportive role when needed. This perspective is particularly relevant for athletes who may have higher nutrient requirements due to their training regimens.
