Vitamin D

No longer is Vitamin D considered just about Calcium and bones.  The minimum requirement used to be 400IU/day, enough to prevent the bone disease Ricketts.

Vitamin D receptors have been found on and in several organs, such as immune cells, brain, gastro-intestinal lining, kidneys, muscles, as well as bone.  Functioning as a chemical messenger and pro-hormone, Vitamin D deficiency can be part of a host of conditions of ill-health.  It is obtained in the diet predominantly in seafood and fortified dairy products.

It  is suggested that 20 minutes of sunshine per day on bare skin will produce adequate Vitamin D.  However, this assumes that you are actually capable of  doing this, and does not consider the lack of sunlight during our northern winters.  For instance, there is more multiple sclerosis(MS) in the northern latitudes, and exacerbations are more common in the darker months.

In my opinion, establishing baseline Vitamin D levels is important, and can easily be obtained through a simple and inexpensive blood test.   Any woman with bone loss, or anyone with chronic pain should consider evaluation and supplementation if necessary.
