Is Your Vitamin D Level Normal?

For those of you that have gone to your doctor recently for a general checkup and had laboratory blood work obtained, chances are that your physician ordered a Vitamin D level.  If so, there is a pretty high likelihood that you were notified that your Vitamin D level is “below normal”, with the normal lab reference range being between 30-100 ng/ml.

Before we discuss Vitamin D, here are my thoughts on “normal” Vitamin D levels.  One would think that “normal” ranges would have have the majority of people in that normal range. However, in the case of Vitamin D, easily 90-plus percent of the patients I test have levels below 30 ng/ml.  So, this gives us pause to think again about what is “normal” in terms of blood levels.

Back to Vitamin D: This fat soluble vitamin is important for calcium and phosphorus absorption, which in turn, is important for bone growth and overall bone health.  Vitamin D is also involved in a number of body chemical reactions.   These impact the immune system and inflammatory system.  Vitamin D has also been shown to reduce the growth of cancer cells.

The foods that are high in Vitamin D: Milk, mushrooms, fish, red meat, yogurt, eggs and fortified cereals.  Clearly, an easy way of obtaining more Vitamin D is via the use of a Vitamin D supplement.

For people with very low levels of Vitamin D or those people whose levels do not go up to the normal range despite taking an over the counter Vitamin D, prescription strength Vitamin D (50,000 IU) is available through a physician’s prescription and this is taken only once a week.

If you have not had a Vitamin D blood test measured in awhile, get into your doctor’s office for a check.  But do not be surprised if the level is below the bottom normal of 30 ng/ml.

And to end today’s entry, although the song is not about Vitamin D, as the temperatures recently have been reaching the 80’s, summer is almost here.  Enjoy Chad and Jeremy’s “ A Summer Song”…introduced by Dick Clark.
