Role Of Vitamin D In Our Lives


We all know that the best source of Vitamin D is sunlight. It is synthesized in our bodies if we expose ourselves in sunlight for some time every day. This vitamin is essential for making our bones and muscles stronger. It also improves our regular physiological functions.  We are often deficient of Vitamin D if we use sunscreen before going out or if we are staying at extreme cold climate. In such cases we need to take Vitamin D supplements to replenish the deficit amount. Vitamin D is responsible for controlling our calcium level in the body.

Deficiency symptoms of Vitamin D

There are people who have deficiency of Vitamin D and still their bodies do not show any clear symptoms. Usually those who are severely deficient of Vitamin D have aches in the joints and muscles accompanied with tiredness. At times there are various infections due to lack of Vitamin D in body.  The most accurate way of understanding whether we are deficit of this vitamin is to undergo a blood test 25(OH) D. in children deficiency of Vitamin D leads to rickets in which the bone tissues cannot mineralize and the bones are susceptible to gradual deformation. In the adults, it leads to osteomalacia in which bones become weak which can be identified with pain in joints and muscles.
