What is the primary purpose of dietary supplements?

The primary purpose of dietary supplements is to provide nutrients that may be lacking in a diet. This is particularly important in situations where individuals may not be able to obtain all the necessary vitamins, minerals, and other nutrients solely through their regular food intake. For example, people with restrictive diets, certain medical conditions, or increased nutritional needs—such as pregnant or elderly individuals—may require supplements to help meet their nutritional requirements and maintain overall health.

Dietary supplements can come in various forms, including vitamins, minerals, herbs, amino acids, and fatty acids, and they are designed to complement the diet rather than replace it. They serve an essential function in helping individuals achieve adequate nutrient intake, addressing deficiencies, and supporting specific health goals or needs.
