What is Vitamin D?
What role does it play in the functioning of your body?

Vitamin D

Vitamin D is a nutrient which are available in food products and is crucial for the maintenance of your strong bones and overall health of your body. Vitamin D can help the body to absorb calcium (from food and other supplements), which is the main building block for the skeletal system and bones health.

In addition, the presence of vitamin D is important for the function of the body as it helps nerves carry messages from the brain to other body parts and muscles. Vitamin D plays a role in aiding the immune system to combat the invading viruses and bacterias. Due to its importance, almost all the cells in your body contain vitamin D.

Vitamin D and calcium can combine to help older ones, who have a tendency of developing thin, brittle and soft bones ,through a medical condition known as osteomalacia in adults and rickets in children and small babies, to develop stronger bones.

Health problems resulting from Vitamin D deficiency

Osteomalacia (in adults): Lack of vitamin D can cause bones in the adult body to become weak or brittle. People suffering from osteomalada experience weakness in their muscles, have prevalent body pain or feel that their bones are fragile. Difficulty walking and proclivity to bone fractures are also signs of this disorder. Individuals suffering from osteomalada are often advised to increase their intake of vitamin D.

Rickets (in children): Vitamin D deficiency can prevent children’s bodies from absorbing phosphorus and calcium required for stronger bones, making their bones soft, weak and brittle. Children who do not get enough vitamin D can experience delayed growth, chronic pain in the legs, spine and pelvis, or bowed legs. A diet rich in vitamin D can help prevent Rickets in children.

Will staying under the Sun get you your dose of vitamin D?

The Sun helps us build up vitamin D levels in our body. Our vitamin D requirements may be met, by exposure to direct sunlight. Despite this too much sun exposure can have some adverse effects.

Direct sunlight may cause skin damage and sunstroke. Exposing unprotected skin to harmful UV rays may also lead to skin cancer.

Moreover, it may be difficult to be exposed to direct sunlight in winter, especially in northern states. Those that work at night cannot depend on the Sun as a source of vitamin D. Some researchers have studied that short sun exposure time might affect vitamin D insufficiency and be relevant to cancer risk.
