Main Article

Vitamin D is a steroid vitamin which promotes the intestinal absorption and metabolism of calcium and phosphorus. It is a pro-hormone that is synthesized in the body when exposed to sunlight, and hence, is called the sunshine vitamin. It is a group of vitamins, including calciferol (Vitamin D2) and cholecalciferol (Vitamin D3), found mainly in liver and fish oils. It plays a vital role in the absorption of calcium, and hence benefits the body in several ways.

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

  1. Vitamin D1 is as molecular compound of ergocalciferol with lumisterol.

  2. 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.

  3. Vitamin D3 is made in the skin when 7 dehyrocholestrol reacts with ultra violet 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.

  4. Vitamin D4 is dihydroegocalciferol.

  5. Vitamin D5 is made up of 7 dehydositosterol

Vitamin D and Pregnancy

Vitamin D is essential and beneficial from the birth of baby as it plays a vital role beyond calcium and bone metabolism on the health status of both the mother and her fetus. Both need equal proportion of Vitamin D. Women who take high doses of vitamin D during pregnancy have greatly reduced risk of complications during delivery. Moreover it improves maternal vitamin D status and reduce the risk of pre-eclampsia, low birthweight, preterm birth and and gestational diabetes

Vitamin D and weight loss

In order to function our body needs energy. Exactly like how a car needs fuel to function, energy is required to make your brain function, your lungs to breathe, your heart to pump blood, your digestive system to function etc. And if our body doesn’t get the energy for all the routine activities, then it will take energy from our fats stores. This is how “weight loss” or “fat loss” happens. The food we consume is combination of carbohydrates, protein and fats which is our caloric energy. This energy is used for exercising and for basic biological processes, known as the basal metabolic rate that the body performs while at rest. These include functions like blood circulation, the regulation of hormones, cell growth and digestion. Any calories that are not immediately metabolized for energy are stored in the body as fat for future use. And for many individuals this excess fat accumulates around the waistline for easy access to the bloodstream through the digestive system. Finally vitamin D comes into picture as inclusion of vitamin D within the bloodstream will alter the storage and formation of fat cells and increase the serotonin and testosterone levels in the body which will instruct brain it’s time to use fat and eventually helps in fat loss.

Vitamin D and Sunlight

There’s good reason why vitamin D is called “the sunshine vitamin.” Exposing our skin to the sun for 20 minutes a day would ensure enough ultraviolet B rays hit the cholesterol in the skin, thus, providing the energy for Vitamin D synthesis to take place.Ideally, one must look to go out at around midday since this is when the sun is at its highest and the UVB rays are the most intense. So that we need less time in the sun to make sufficient vitamin D.

Vitamin D And Mental Health

Do you ever wondered what happens to our mind when we crave for spicy junk food when we are on diet? Our mind releases dopamine that gives indication to brain that cravings will be fulfilled soon. Higher the dopamine our cravings will be higher. Besides,dopamine is also known as feel good hormones. The functioning of dopamine depends on proportion of vitamin D and our mental health depends on release of dopamine. So vitamin D, dopamine neurons and mental health are interrelated.

Magic! Isn’t it?

Moreover if anyone is unable to bear sunlight then either consume vitamin D rich foods or it’s advisable to consult doctor to avail best vitamin D supplement or for efficiently regulating all the bodily functions.

Vitamin D and Skin

The anti-oxidant present in Vitamin D prevents skin damage and premature ageing of skin when taken via supplements or included in diet.

Besides, one of the most well-known uses for Vitamin D in terms of skin is its treatment of psoriasis. Psoriasis symptoms include itchy and flaky skin, which can heal by the topical application of Vitamin D cream or by having prescribed Vitamin D supplements.

Vitamin D as best source of healthy well-being

As it plays significant role in maintaining healthy bones. It protects against respiratory infections like cold, flu etc. It has reduced risk of heart diseases, stroke and heart failure. And the most interesting part is it reduces the risk for type 1 and 2 diabetes as it increases insulin levels and it efficiently manages sugar level.. In simple words, vitamin D efficiently support the immune system and fight inflammation.

Heart disease

Heart disease and vitamin D deficiency are known to go hand in hand; one sobering 2009 study published in the Journal of Clinical Endocrinology and Metabolism found that subjects with extremely low levels of vitamin D were nearly three times as likely to die of heart failure and five times as likely to die of sudden cardiac death.


Lupus, a chronic inflammatory disease in which the body's immune system attacks its own organs and tissues, is frequently associated with vitamin D deficiency—in part because lupus patients are often advised to stay out of the sun (the source of 90% of our vitamin D), and may be prescribed corticosteroids, which are also linked to low levels of D

Inflammatory bowel disease

Vitamin D deficiencies face gastrointestinal health issues that affect their body's ability to absorb nutrients. Patients with active ulcerative colitis, a type of inflammatory bowel disease (IBD), especially those who take corticosteroids, are often deficient in D, a study in Digestive Diseases and Sciences suggested, and some researchers believe deficiency could have a role not only in increasing the risk of developing IBD but in determining the severity of a person's symptoms.


Rickets, or the softening and weakening of bones in children, is usually caused by an extreme and prolonged vitamin D deficiency; children who are 3 to 36 months old are at highest risk because their bones are growing so fast. The American Academy of Pediatrics recommends that all infants, children, and adolescents receive a minimum daily intake of 400 IU of vitamin D.

Childhood language impairment

Women who suffered vitamin D deficiencies at 18 weeks pregnancy had nearly double the risk of having a child with signs of language impairment at ages 5 and 10 compared to women with higher levels, according to an Australian study published in Pediatrics. The results don't prove that vitamin D causes those difficulties, but they do highlight its importance in fetal brain development; it's possible that prenatal vitamin D supplementation may reduce the risk of developmental language problems in children.

Moreover there is no end to the list of diseases that will get lined up to serve with amazing gesture. Just imagine condition of human being who is undergoing so many health issues!
