Health Benefits and Uses of Vitamin D | Vitamin D Benefits

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.

Before going into Vitamin D benefits, look into its best sources and deficiency symptoms.

Normally a bare skin exposed to the sunlight for 5-10 minutes, 2-3 times per week gives the body enough ability to produce vitamin D in sufficient quantity.

But as vitamin D has only 2 weeks of half-life, the body will soon run out of vitamin D like in the winter season.

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.

In the adults, osteomalacia or osteoporosis is the common disorder because of Vitamin D deficiency. In both cases, the bones become weak and fracture-prone.

Prevention of Cancer

Vitamin D also supports cell growth and the communication from one cell to other. Now many studies have proven that the calcitriol which is the very active hormonal form of vitamin D has the ability to reduce cancer progression.

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.

Vitamin D is one of the most potent inhibitors of cancer-cell growth and reduces the risk of cancer by increasing calcium absorption and cell differentiation while reducing metastasis (the spread of cancer from one organ to another)

Protection from Diabetes (Type 2)

Many studies have conducted to see the relation between diabetes and vitamin D. In most cases it has been found that vitamin D has an inverse relation with diabetes, which means the deficiency of vitamin D maximizes the risk of having diabetes.

Recent evidence suggests that vitamin D may play a significant role in reducing the risk for type 2 diabetes—especially in those who are at an increased risk for this deadly disease.

A lower amount of vitamin D also affects insulin secretion and glucose tolerance.
