Vitamins have great health benefits for our skin, body and energy levels. We will be better off knowing a little more about them. Let’s take a look at Vitamin D Benefits and how we can incorporate it into our daily routine.

What is Vitamin D?

Vitamin D is a group of fat-soluble steroids which aid in the absorption of calcium and phosphate by the intestine.

The sunshine vitamin or vitamin D is a fat-soluble or one can say lipid soluble steroid. Vitamin D helps in regulating the amount of phosphate and calcium in our body and helps bones, teeth, and muscle to stay healthy.

Though it is named as vitamin it is considered as prohormone as our body is capable of generating vitamin D by itself and vitamins are that nutrients which are not possible to synthesize by the body and must be provided through supplements or diets.

There are 5 forms of Vitamin D and collectively they are known as calciferol.

  • Vitamin D1 is a molecular compound of ergocalciferol with lumisterol.
  • Vitamin D2 is made of ergosterol. It is produced in invertebrates, fungus, and plants in response to sunlight. Humans and other vertebrates do not produce Vitamin D2.
  • Vitamin D3 is made in the skin when 7 dehyrocholestrol reacts with ultraviolet light. A human requires 10 to 15 minutes of sun exposure at least twice a week on the face, arms and back without sunscreen with a greater than 3 UV index for adequate amounts of Vitamin D3 synthesis.
  • Vitamin D4 is dihydroegocalciferol.
  • Vitamin D5 is made up of 7 dehydositosterol.
  • Out of all these Vitamin D2 and D3 are most important.

Recently studies on vitamin D deficiency have shown that about 50% of adults as well as the child, worldwide, face vitamin D deficiency.

Generally, people who live in high altitude have minimum sun exposure which is why they need to have foods which are the sources of vitamin D or they need to take supplements.

A person with fair skin if exposed full body to the sun can produce up to 20,000 IU of vitamin D3 within 20 minutes. It is produced when the cholesterol on our skin is converted into vitamin D3 or calciol.

Then in the liver calciol is converted into calcidiol or 25-hydroxyvitamin D3. After that calcidiol is converted into vitamin D or calcitriol in the kidney.

Calcitriol increases the death of cancerous tissues by lowering the speed of the growth and development of new blood vessels in the carcinogenic tissues hence, the cell proliferation and metastases process also get reduced.
