With our trend toward fast-food diets, we could probably all use a multi-vitamin daily. For those women of child-bearing age, I routinely recommend prenatal vitamins on a daily basis, not just during pregnancy. Menstruating women can use the extra iron to help prevent anemia, sometimes associated with monthly blood loss. Calcium early in life may help prevent osteoporosis as we age. Many vital organs in a fetus, such as the neural tube, are formed prior to knowledge of pregnancy. By taking prenatal vitamins routinely, the fetus has the needed vitamins and minerals at the time of development. Once delivered, moms also can use the extra nutrients during breastfeeding or recovering from blood loss at the time of delivery.
