Supplements are a good way of providing your body with the nutrition it lacks in. Nutritional food supplements are the best to go for when we do not have the time to take care of nutrition in our diet. They are also known as dietary supplements. This covers all the important minerals, proteins, vitamins, fats, carbohydrates etc. Supplements are a useful way to get the nutrition you otherwise lack in your diet. They can never be substitutes of food as such because they cannot replace the natural nutrition and the nutrients provided by actual food. They can never really replace whole foods like fruits and vegetables. You have to keep an eye on how your situation is and then depending on your eating habits you can decide if there is a need to take nutritional food supplements.
