Nutritional surveys consistently indicate that a substantial number of people in different countries fail to get the required amounts of nutrients from their daily meals. Dietary supplements were introduced at the beginning of the 20th century to fill this deficiency gap. Their use among all cohorts of world populations has grown tremendously over the years. Multivitamins are among the most widely used types of food supplements. The benefits of vitamin supplements range from reducing the risk of developing chronic health conditions to treating different disorders. Different multivitamins contain different nutritional substances. Multivitamins containing folic acid, for example, can significantly reduce the risk of a woman having a baby with neural tube birth defect. Folic acid, vitamins B-6 and B-12 should be taken by the general public to reduce the incidence of cardiovascular diseases. vitamin C does protect the skin and is also good for strengthening the immune system. Vitamins also play a role in weight loss. Adequate amounts of B vitamins and other nutrients help in metabolising dietary proteins, carbohydrates, and fats. Vitamin supplements are also crucial for healthy bones and teeth. Children and the elderly need a constant intake of Vitamin D supplements especially if they don’t get sufficient dairy products in their daily diets. It should be noted with clarity that though there are many benefits of vitamin supplements, they are only meant to complement and not replace meals.
