In my recent blood work for my annual physical, my Vitamin D, 25-Hydroxy test was measured at 17.3 or an insufficient level. Probably not enough sun during the winter; still, even with all the supplements I’ve been taking I managed to avert influenza and colds this season. Knock on wood!
I was very diligent in taking 5000 mg of D-3 everyday yet my levels were somewhat surprisingly low. Perhaps it was the vitamin manufacture because you can never know which Vitamin Company you can trust to provide the best product. I’ve switched over to GNC … perhaps that will help.
Anyway, I’m always interested in local Thousand Oaks authors and Doctor Zaidi recently published the Power of Vitamin D. I heard about him from a fellow Choir member who recommended reading his books.
It’s not like I’m new to the vitamin and I’ve been a big fan of Vitamin D ever since seeing Dr. John Cannell’s video and how he found a relationship between influenza and Vitamin D deficiency.
While Dr. Cannell has a good overview of what the vitamin can do for your, Dr. Zaidi’s book fills in all the information on how much you should be taking to supplement your diet and what levels should be found in your blood.
I enjoyed his level of writing where it wasn’t too technical and very easy to understand. His conclusions of why we are having an deficiency epidemic: modern lifestyle, sun phobia and obesity is somewhat obvious other than obesity, but he gives good examples of the cause of the problem.
Is this book for you? If Dr. Cannell’s video excites you about the power of vitamins, then you should pick it up and read it. I’m fairly certain that you or someone you know can benefit from the Power of Vitamin D.

If you keep on taking supplements and think your vitamin d level is low check your 1-25d.
