Vitamin D is a group of fat-soluble secosteroids
responsible for increasing intestinal absorption

In humans, the most important compounds in
this group are vitamin D₃ and vitamin D₂

7. Role of Vitamin D
Your body must have vitamin D to absorb
calcium and promote bone growth.
Too little vitamin D results in soft bones in
children (rickets) and fragile, misshapen bones
in adults (osteomalacia).
You also need vitamin D for other important
body functions.

8. Sources of Vitamin D
Fatty fish, like tuna, mackerel,
and salmon.
Foods fortified with vitamin D,
like some dairy products,
orange juice, soy milk, and
cereals.
Beef liver.
Cheese.
Egg yolks.

The recommended daily amount
of vitamin D is 400 international
units (IU) for children up to age 12
months,
600 IU for ages 1 to 70 years,
800 IU for people over 70 years.

therapy has been found to
cause nausea, vomiting
and lack of appetite for

Vitamin D deficiency can lead to
a loss of bone density, which can

fractures. Severe vitamin D

diseases. In children, it can
cause rickets. Rickets is a rare
disease that causes the bones to
become soft and bend.
