That goes up to 800 IU a day for those older than age 70. To meet this level, choose foods that are rich in vitamin D. For example, choose fatty fish, such as salmon, trout, tuna and halibut, which offer higher amounts of vitamin D, or fortified foods, such as milk and yogurt. Don't overdo it, though.
