Everything You Need to Know About Vitamin D

Everything You Need to Know About Vitamin DVitamin D, commonly known as the “sunshine vitamin”, is considered a pro-hormone and not a vitamin. This is because the human body cannot produce vitamins, and they need to be consumed through diet.However, Vitamin D is different. It can be synthesized by the human body using the sunlight it catches when we are out and about in the sun. Every cell in the human body is affected by this prohormone. Vitamin D is essential for good bone health, as well as for absorption of calcium.

Vitamin D3 and Vitamin D2 supplement best known to help maintain Vitamin D levels in your bloodstream. While food products like fatty fish, such as salmon, mackerel and tuna, orange juice, soymilk, cereals, cheese, mushrooms, cod-liver oil, sunflower seeds and egg yolks, are rich sources of Vitamin D.

Despite being endowed with plentiful sunlight, Vitamin D deficiency is rampant in India. As per research studies carried out in recent times, almost 65 to 70 percent of Indians are suffering from Vitamin D deficiency. Considering this, it is important for Indians to understand the need and the benefits of the sunshine vitamin.

The sunshine vitamin has numerous important functions. Some of them are:

  • Adults, as well as children, require a certain amount of Vitamin D in their blood. Vitamin D is vital for strong teeth and healthy bones. It helps the body in calcium absorption, and aids in the regulation of phosphate and calcium levels. Maintaining sufficient levels of Vitamin D are linked to the prevention of osteoporosis.
  • The sunshine vitamin also acts as a hormone and is essential for the stable functioning of the brain. It is also vital in ensuring good health of blood vessels in the body.
  • Studies in recent times have concluded that Vitamin D plays a crucial role in the prevention of heart diseases, ensures good health of a respiratory and immune system, as well as works towards maintaining breast health.

Ideal Vitamin D levels

According to the Indian Council of Medical Research (ICMR), a daily supplement of 400 IU/day of vitamin D is necessary for Indians with minimal exposure to sunlight.

There is a growing consensus supported by research, which suggests that we need to consume up to 1,000 IU of Vitamin D to ensure maintaining the required levels in the blood. Many times, doctors recommend maintaining higher levels of Vitamin D depending on your body needs. Therefore, it is essential to take the advice of a doctor before starting supplements for Vitamin D.

Risks of D-deficiency

In adults, deficiency of Vitamin D is concluded when the blood level is less than 50nmol/L. In children, Vitamin D deficiency is considered when the blood levels show the vitamin content 25 nmol/L or below. When suffering from a D-deficiency, the body is unable to absorb and maintain the levels of calcium and phosphate. When these minerals are too low in the bloodstream, other hormones work towards releasing them from the bones into the bloodstream to regulate the levels. Vitamin D deficiency in adults affects both the bone, as well as heart health. In children, the deficiency can lead to rickets, which is a progressive weakening and softening of the structure of the bones.
