Power of Vitamin D

"Power of Vitamin D," has become a popular and a reference book on the topic of vitamin D.This book contains all the important information you need to know about Vitamin D including the wonderful health benefits of Vitamin D.

In this book, Dr. Zaidi dispels common myths about Vitamin D, such as "being outdoor in the sun for 15 minutes a day is enough to take care of your Vitamin D needs." Wrong! 

Dr. Zaidi explains what level of Vitamin D you need in order to take advantage of these miraculous heath benefits of Vitamin D without risking toxicity. 

Most people are low in Vitamin D and they don't even know it! Sadly, most physicians are not up to date on Vitamin D. They often order the wrong test for Vitamin D level, which can be normal even if you have a severe deficiency of Vitamin D! 

Many physicians interpret test results of Vitamin D with the myopic eye of the reference range provided by the laboratory. These reference ranges are often wrong when it comes to Vitamin D.
