Vitamin D is one of the most important vitamins for the body present in sunlight and some foods. When an individual has a lesser amount of vitamin D in the blood, it means they have vitamin D deficiency. By taking a well-priced blood test for vitamin D test deficiency, one can determine the levels of this vitamin in the body and can take suitable treatment.

Why is Vitamin D Important?

Vitamin D plays a vital role in the functioning of bone health, mental health, and immunity. Also known as the sunshine vitamin, if a person does not have enough of it, they may have abnormal levels of blood calcium, extreme fatigue, depression, and other health conditions.


Several people have vitamin D deficiency due to varying reasons. Mentioned below are the most commonly observed causes of this medical condition:

1. Limited Exposure to the Sun

One major source of vitamin D is the sun and having minimum exposure to it may lead to vitamin D deficiency. People who do not go out in the daytime or have very little sunlight available in their region are prone to this deficiency.

2. Strict Diet

Another major reason for having vitamin D deficiency is when one follows a strict dietary regime. Typically, people who are on a vegetarian or vegan diet are more likely to have this deficiency. This is because most non-vegetarian food sources like eggs, fish oil, beef liver, etc., are rich in vitamin D, which they do not consume.

3. Unhealthy Kidneys

Individuals who have unhealthy kidneys are unable to convert vitamin D to its active form, making them prone to vitamin D deficiency. 


Generally, individuals with this deficiency are asymptomatic and only a test for vitamin D deficiency can help a medical practitioner get the correct answer. However, there are a few indications that can point out that a person may have vitamin D deficiency. These symptoms include:

  • Depression or the feeling of sadness
  • Fatigue
  • Insomnia
  • Pale skin
  • Bone or muscle pain

Individuals should book vitamin d test online to check vitamin D levels in the body. If the vitamin D is at abnormal levels, then the person should start taking care of their diet and overall health. It is vital to take the test for vitamin D deficiency from a reputed pathology lab to ensure accurate results.
