An Epidemic of Vitamin D Deficiency




The fact is that most of us are low in Vitamin D.


At the Jamila Diabetes & Endocrine Medical Center, which is located in sunny Southern California, we routinely measure Vitamin D in our patients.


More than 90% of our patients are low in Vitamin D! Many of these patients drink milk and take a multivitamin as well as a calcium tablet that contains vitamin D.


So why is Vitamin D deficiency so common?  


The sun is the main source of Vitamin D and accounts for 90% of Vitamin D in our body. Upon exposure to the sun, our skin manufactures Vitamin D, which then finds it's way into the blood stream. Cholesterol is the raw material for the synthesis of Vitamin D.


Most of us don't get enough sun exposure. Often our jobs and lifestyle forces us to stay indoors. Even when we do go out in the sun, we make sure to put a healthy layer of sun-screen which blocks the synthesis of vitamin D in our skin. Even most makeup now contains sun-screen. 


Unfortunately, we're not told that the sun is beneficial as well. The truth is that the sun is both good and bad for us. It provides us with Vitamin D,  but may also zap us with an occasional skin cancer.
