Normal Vitamin D ranges: Not at all normal


vitamin D

Thinning or breaking of bones is the most read or heard effects of vitamin D deficiency. However, a deficiency of vitamin D can be more dangerous than these. Vitamin D is one of the most essential vitamins that help in maintaining the overall health of the body. Starting with strengthening bones, controlling cardiovascular diseases, diabetes and many other major diseases, Vitamin D has a very crucial part to play.

In order to get the required level of Vitamin D, people usually consume supplements. However, they aren’t sure about the right level of vitamin D. The topic of ‘right level of vitamin D is quite debatable’say, if there is one appropriate level, what is it and how to know? 

 The Cutoff Value of Vitamin D

 Now, there is much hype about the cutoff level of vitamin D that is considered as the apt range. Studies have shown that the blood level of 25 hydroxy-vitamin D (given that it is calculated in nanograms per millilitre)  can be considered as the above-mentioned cutoff level.

However, this level has many chances of raising arguments. A study conducted by the Institute of Medicine in the year 2010 has stated that a vitamin D level of 20ng/ml or even higher is absolutely adequate for a human body. With that, a level of vitamin D below 20ng/ml can cause deficiency.

However, in the year 2011, the Endocrine Society’s reports say that vitamin D level of 30ng/ml or higher is adequate for a healthy body. Nevertheless, the same report also says that children and adults should have the level of vitamin D ranging between 40 ng/ml and 60 ng/ml.

Contradicting to the above-mentioned range, the report published by the New England Journal of Medicine has a very different argument to make. It says that while the cutoff range of 20 ng/ml is considered as low and can cause deficiency, the study says that there is no definite cutoff range and one can not define deficiency of vitamin D if the range drops down to 20 ng/ml. This study also claims that as the world has largely accepted 20 ng/ml as the limit, even healthy individuals are being diagnosed with a deficiency in vitamin D.

Arguments regarding the required levels of vitamin D keeps rising while the speculations vary from one team of experts to others. This makes it difficult for a commoner to know the required level of Vitamin D Therapy.

Though we don’t have an actual number, let us assume that the normal level of vitamin D required by everyone should be more than 20ng.ml. Also, as children are at a growing stage they might need a little higher level of vitamin D in their body. The same goes with elder people, with age the bones tends to be weaker and to keep it strong it is advisable to maintain the level of vitamin D bit higher always.

There is no way to know if a human body is deficient of vitamin D unless one feels bone weakening or breaking (without falling or meeting an accident). So, the best way to know it is by testing it and if the results show lower than the desired value, either take supplements or consume vitamin-D rich food.
