Vitamin D deficiency leads to impairment of bone mineralisation ,which leads to Rickets in children, and osteomalacia in adults

The Recommended Dietary Allowance (RDA) for adults is 600 international units (IU) of vitamin D in a day and 800 IU a day, for those older than age 70.

To meet this level, foods that are rich in vitamin D such as fortified foods, dairy products (milk, yogurt), and fish, such as salmon, trout, tuna must be a part of the diet.
