The Basics Of Vitamin D

Today in this blog topic in CRB Tech Reviews, we shall discuss about the wonder vitamin, yes! We are talking about Vitamin D.

Vitamin D is essential for good health and strong and healthy bones. Also an important factor in making your muscles, heart, lungs and brain work very well and helps your body fight infection.

Your body can make vitamin D from sunlight. You can also get them as supplements and a very small amount comes from your diet.


Roles Of Vitamin D

Vitamins are needed by your body for good health. They are vital for everyone and make sure that your body works well, is able to fight illness and heal well.

The link between vitamin D and strong healthy bones was made many years ago when doctors realized that sunlight, which allows you to produce vitamin D, helped to prevent a bone condition called rickets in children. Today, vitamin D is seen as a vital part of good health and it’s important not just for the health of your bones. Recent research is now showing that vitamin D may be important in preventing and treating a number of serious long term health problems.

Getting the right amount of vitamin D doesn’t depend on the foods you eat! Instead, getting the right amount depends on sun exposure and if you take a supplement with the right amount.

A wonder vitamin because your body can make its own vitamin D when your skin gets exposed to sunlight. But your body can’t make other vitamins.

Also what makes vitamin D unique compared to other vitamins, is that when  your body gets its vitamin D, it turns vitamin D into a hormone. This hormone is sometimes called “activated vitamin D” or “calcitriol.”

Vitamin D is very important for strong bones. Calcium and phosphorus are essential for developing the structure and strength of your bones, and you need vitamin D to absorb these minerals. Some of the functions that vitamin D helps are:

  • Immune system
  • Muscle functionality
  • Heart and blood function
  • Respiratory system
  • Brain development
  • Anti-cancer

Doctors are still working to fully understand how vitamin D works within your body and how it affects your overall health.


If your body doesn’t get enough vitamin D to keep it healthy, this is called vitamin D deficiency. Severe vitamin D deficiency can sometimes cause a condition called rickets in children and a condition called osteomalacia in adults. Both of these conditions cause soft, thin, and brittle bones.

A lack of vitamin D has also been linked to some other conditions such as cancer, asthma, type-II diabetes, high blood pressure, depression, Alzheimer’s and autoimmune diseases like multiple sclerosis, Crohn’s and type-I diabetes.

How does Vitamin D work?

Vitamin D maintains calcium in your body and helps cells to communicate properly.

Vitamin D mainly comes from skin when it is exposed to sunlight. After that, your body goes through a number of chemical processes to make them accessible by your body.

When your skin is exposed to the sun, it produces vitamin D and sends it to your liver. Then your liver changes it to a substance called 25(OH)D. When your doctor talks about your vitamin D levels, he means the amount of 25(OH)D you have in your blood.

This chemical is sent all over the body where different tissues, including your kidney, turn it into activated vitamin D. This activated vitamin D is now ready to perform its duties. Activated vitamin D works in two ways:

  1. Maintains calcium in your body
  2. Helps cells to communicate properly

Vitamin D goes a long journey from its initial form in skin, supplement or food. But without this your body can’t perform at its best.

We conclude now.
