Vitamin & Mineral Needs: 50+
They say turning 50 is a milestone, and it is, if only because certain nutrient needs change at this juncture of life. You may notice no difference in your health, or your energy level, but nutrition experts say this is an important time to evaluate your diet so that you can be as active as you like.
Here are some of the most important mid-life changes in vitamin and mineral needs for men and women, as determined by the Institute of Medicine (IOM).
Men and women over age 50 should get most of the suggested daily vitamin B12 from dietary supplements or from foods with added vitamin B12, such as breakfast cereal. Here’s why. After 50, many people absorb less of the naturally-occurring vitamin B12 from foods, such as meat, milk, and eggs. That’s because the body produces less stomach acid, which is necessary to absorb vitamin B12 in its natural form. Synthetic vitamin B12, the type added to fortified foods and dietary supplements, can be absorbed without stomach acid.
