When are dietary supplements beneficial?

Dietary supplements are particularly useful when it is difficult to obtain sufficient nutrients through diet alone or when the body's nutritional requirements are increased. This may apply during certain life stages, such as pregnancy, breastfeeding, or older age, as well as for people with an active lifestyle, those following a vegetarian or vegan diet, or individuals with diagnosed vitamin or mineral deficiencies. Supplements are intended to complement the diet and help prevent nutrient deficiencies, but they should not replace a balanced and varied diet.
