Vitamin D Deficiency: Symptoms, Causes, Tests and Treatments

The skeletal system of our body is also the framework on which each muscle and nerve is attached. Therefore, it is extremely necessary to ensure that the bones within the skeletal system are in the best shape. Vitamin D is the most important nutrient that should be included in the daily diet of every individual, irrespective of age. Here is all the necessary information about the deficiency of vitamin D, its causes, symptoms and the best ways to treat the deficiency.

Introduction to Vitamins

Vitamins are considered to be essential nutrients for the body as they are created in negligible amounts. Due to such a situation, it is important to consume them in adequate amounts to reduce the chances of deficiency, especially of Vitamin D. Counted along with other Vitamins A, E and K that are fat-soluble, Vitamin D is available from a wide range of sources like animal foods, supplements, fortified food and ample amount of sunlight. It is important to keep in mind that there are specific limits for people to consume. The points below will help in understanding the specific amounts that are permissible for consumption:

  • From birth to 1 year - 400 IU
  • From 1 to 13 years of age – 600 IU
  • From 14 to 18 years of age – 600 IU
  • From 19 to 70 years of age – 600 IU
  • From 71 years and above – 800 IU

Apart from the above levels for a normal human being, the intake level for pregnant and lactating women should also be 600 IU. It is also necessary for people with a pre-existing condition where they have a deficiency of Vitamin D. In such a situation, it is advisable for the affected individual to get their Vitamin D levels tested.
