Vitamin D has amazing health benefits. From Cancer to  Heart disease, Diabetes to Asthma, Osteoporosis to Common colds, and many more diseases, vitamin D has amazing healing power. Unfortunately most people suffer from Vitamin D deficiency and its serious health consequences.

Vitamin D finally got attention by the news media. Like everything else, news media has done a good as well as a bad job. While it created some awareness about vitamin D, it also circulated a lot of misconceptions

For example, most people don't know that Vitamin D is not a Vitamin but a Hormone. You can't get enough Vitamin D by going outdoors 15 minutes a day or by eating certain kind of food items or drinking a cup of milk a day or taking a daily multivitamin. Food items contain very little Vitamin D. Most people are also scared to death about vitamin D toxicity. 

In order to find facts about vitamin D you need to learn from an endocrinologist, the hormone specialist. In this regard, we highly recommend a popular book, "Power of Vitamin D," written by Dr. Sarfraz Zaidi, MD, a leading endocrinologist and an expert of vitamin D.
