<p>Vitamins themselves do not have calories. Calories are a measure of the energy content in food, specifically the energy that the body can obtain by digesting and metabolizing it. Vitamins, on the other hand, are organic compounds that the body needs in small quantities to maintain normal physiological functions. While some vitamin supplements may contain fillers or other ingredients that do have calories, the vitamins themselves do not contribute to the calorie count of a food or supplement. However, it’s worth noting that some foods that are high in certain vitamins may also be high in calories, so it’s important to consider the overall nutritional value of a food or supplement when making dietary choices.</p>
