Many adults do not get enough vitamin D. And we need it to keep our bones strong. It also helps support your immune system and lowers inflammation. Guidelines suggest that most adults need 600 to 4,000 international units a day. You can get vitamin D from salmon, egg yolks, and from foods that have vitamin D added, like milk, cereal, and orange juice. Your body also makes vitamin D when you spend time in the sun. But you don’t want to overdo your exposure to the sun.
You can also get vitamin D from a pill. But, before you take this supplement, be sure to ask your doctor how much is safe and right for you. For most healthy people, whole foods are the best source of this nutrient.
