Vitamin D Deficiency and Treatment


Vitamin D is an essential vitamin that has powerful effects on several systems throughout the body of a human being. Actually, the human body makes it from cholesterol when the skin is exposed to sunlight. Also, it is found in some fatty fish, egg yolks, and fortified dairy products, although it is very difficult to get enough from diet alone. The recommended daily intake is usually around 400-800 IU, but many doctors recommend that you should have even more than that.

Vitamin D is necessary for strong bones because it helps the body use calcium from the diet. Traditionally the deficiency of Vitamin D has been associated with diseases like rickets; a disease in which the bone tissue doesn’t properly mineralizes, leading to soft bones and skeleton deformities. But advance research in this field reveals the importance of vitamin D in protecting against a many of health problems.

The common risk factor for vitamin D deficiency:

  • Having dark skin
  • Being elderly
  • Being overweight or obese
  • Not having milk, fish, and egg in diet

  • Always using sunscreen when going out of the house
  • Staying indoors for longer period

Most of the people who live near the equator and frequent sun exposure are less likely to be deficient because their skin produces enough vitamin D to satisfy body needs. It’s also true that most people do not realize that they are facing the deficiency because the symptoms are generally subtle.
