While experts debate whether supplements are necessary or helpful for most healthy people, eating more of these vitamin D-rich foods is a great way to get what your body needs.

Salmon. Fatty fish like salmon, halibut, cod, and tuna, are one of the best food sources of vitamin D. A 3-ounce fillet delivers about 450 IU, which is close to the 600 IU that experts recommend most people eat each day.

Eggs. And especially the egg yolks, since all of the vitamin D in an egg is found in the yolk. Some eggs boast even higher levels than others - One Eggland's Best egg, for example, contains four times more vitamin D than ordinary eggs, totaling 30 percent of the daily recommended intake.

Fortified Milk. A typical eight-ounce glass of cow’s milk contains at least 100 IUs of vitamin D, but the amount can be higher or lower depending on how much of the vitamin is added. Rice milks and soy milk can be fortified as well; check the label.

Fortified Cereal. A variety of hot and cold cereals are now fortified with vitamin D, and some can contain more than 300 IUs of vitamin D per serving to get you halfway to your daily goal.

Fortified Orange Juice. Like milk, many fortified orange juice brands have extra vitamin D - roughly about 100 IU in an eight-ounce glass. It's often packaged with added calcium too, which is great because vitamin D helps your body absorb the bone-boosting mineral!
