vitamin D deficiency

Vitamin D is a fat-soluble vitamin. It can be classified into two parts: D2 and D3. Vitamin D2, also known as ergocalciferol and obtains from fortified foods, plant foods, and supplements.


Vitamin D3, also known as cholecalciferol, obtains from fortified foods, animal foods (fatty fish, cod liver oil, eggs, and liver), supplements, and from the sun.



vitamin d sources

Your body makes it when ultraviolet (UV) radiation of sunlight touches your skin.


Vitamin D is perhaps the single most underrated nutrient in the world of nutrition. Besides Sunlight the other Vitamin D sources are:

  • Fatty fish, like tuna, mackerel, and salmon.
  • Foods fortified with vitamin D, like some dairy products, orange juice, soy milk, and cereals.
  • Beef Liver.
  • Egg yolks




The main reason for the vitamin D deficiency epidemic in the world is that there is not sufficient amount of vitamin D in the food consumed on daily bases. As per the Vitamin D deficiency statistics, the estimated amount an adult is between 3000 and 5000 IU per day.


As a result of the main source of vitamin D, almost entirely, depends on sun exposure. When an adult is exposed to 1 minimal erythemal dose of UV, a slight pinkness to the skin 24 h after exposure, this amount of exposure produces almost 10,000-25,000 unit vitamin D.


On the other hand in the absence of sunlight exposure, at least 2000-3000 IU of vitamin D is necessary for children and adults to maintain a 30 ng/ml vitamin D in their blood. Source:
