Many studies have recently come out singing the benefits of the super-nutrient, vitamin D, which helps to activate immune cells. It’s recommended that children get 400 IU daily of vitamin D. What’s unique about this nutrient is that you can get it just by enjoying some sun; sunlight triggers production of it in your skin.
Unfortunately, a lot of kids aren’t exposed to enough sunlight, so they’re not getting enough of this important nutrient. It’s important that you provide vitamin-D rich foods such as fortified milk and juices, cheese, eggs, and salmon in your child’s diet. A glass of milk has 100 IU of vitamin D. Unless your child is prepared to drink four glasses of milk a day, which is unlikely, it is probably a good idea to find a supplement with vitamin D in it. Similarly, for infants who are exclusively breastfed, it’s important to find a supplement with 400 IU of vitamin D, as breast milk is deficient in it.
