7-12 months  5 mcg per day (200 IU*)
1-3 yrs  5 mcg per day (200 IU*)

Where Can They Get It?

Vitamin D is known as “the sunshine vitamin,” since our bodies make it after being exposed to sunshine. But since we try to keep our little ones out of the sun, it's nice to know your child can also get vitamin D from fortified food sources:
Infants:
  • Breast milk or fortified formula
Toddlers:
  • Fortified dairy products
  • Fortified cereals
  • formula
Adults:

Ideally every human being is bestowed with this vitamin from the sun without any price but now in the age of cosmetics most women as well as men are deficient of vitamin D. Early morning sunshine for the body is very important and good. 

If not possible there are medically prescribed oral suspension available on doctors consult for pregnant women, menopause period and other category of illnesses.
