Answer:

False.

Explanation:

Vitamin D is very important for our body because it helps absorb, transport and fix calcium rather than sodium, as the question above says. In addition, this vitamin prevents disease and promotes bone maintenance. In order for her to perform her duties, one usually has to expose oneself to the sun.

One of the tips to find out if your body is missing this vitamin is to look at the skin. The sun is responsible for synthesizing vitamin D in the body. So if your skin is darker it is a sign of deficiency as pigment protects the skin and prevents absorption.
