Can you skip your daily servings of fruits and vegetables and take a vitamin and mineral supplement instead? Unfortunately, no. Dietary supplements aren't meant to be food substitutes, as they can't replicate all of the nutrients and benefits of whole foods, such as fruits and vegetables. However dietary supplements can still play a role in your health by complementing your regular diet if you have trouble getting enough nutrients.
Vitamins and supplements are substances your body needs in small but steady amounts for normal growth, function, and health. Together, vitamins and supplements are called micronutrients. Your body can't make most micronutrients, so you must get them from the foods you eat or, in some cases, from dietary supplements.
