Dietary or nutrition experts recommend including seasonal fruits and vegetables, whole grains, milk, and other dairy products; in everyday meals, in order to get a balanced and nutritious diet. Hence the best way to get vitamins and minerals is by eating a variety of healthy unprocessed foods, devoid of any harmful chemical effects; which is rarely found these days. 

But sometimes even people who have the most healthy eating habits find it hard to get all the required food items and in the right amounts. This is where the role of vitamins and other nutritional supplements comes into play. Although all of the currently available dietary supplements cannot fully make up for the unhealthy and junk eating habits, they can help in filling up certain gaps.
