As a pharmacist I highly recommend testing Vitamin D levels. Vitamin D is essential to human health and adequate levels have been associated with improved health and longevity, yet most people are deficient in this very important vitamin. Susan Rex Ryan has done a wonderful job at summarizing the latest research on the importance of Vitamin D is various health issues from autoimmunity to cancer to periodontal health. She summarizes the best sources and ways to use Vitamin D safely and effectively.

The information Susan presents in her book is accessible to patients and at the same time well researched and cited. As a reader, you will feel comfortable with the author’s recommendations. I would highly recommend this book for everyone who is looking to improve their health as it is incredibly informative and written in a way to educate patients on the benefits of Vitamin D.

ss_amazon_bannerVery Informative and Well Written Book! —S. Gebhardt
After having a spine fusion four years ago, I was advised by my neurosurgeon to increase my intake of calcium and vitamin D3. At that time, I did not realize there was any difference between the various types of vitamin D, although my neurosurgeon said “make sure it is D3.” I found the author’s book very easy to read; the information she presented was well-researched, well-documented, and practical for both the layperson and medical professional. I now feel more knowledgeable about the potential benefits of D3 and the how the vitamin may prevent/help various medical conditions ranging from the common cold to cancer. I would highly recommend this book to anyone wanting to learn more about vitamin D3. As the author suggests, I will discuss D3 with my personal physician before increasing the dose. I do have many questions for my doctor after reading this book (and now feel that I am an informed patient). Finally, you can feel the author’s passion about her subject as you read the book. She provided several personal examples that made “Defend Your Life” very interesting. I sat down to BEGIN reading the book and ended up reading it from cover to cover without ever leaving my chair!

As a registered nurse, I am always searching for easy to read books which can provide needed information for my patients. This book fits the bill beautifully. Vitamin D3 is being prescribed by physicians and nurse practitioners more and more. My patients have questions and now I feel fully prepared to answer them. This is well researched and meticulously prepared. I feel confident in giving this information to others. I am particularly interested in the chapters about Cardiovascular disease and Diabetes as many in my patient population are afflicted with these diseases. Thanks to the author for an easy to understand “bible” for my library.

My elderly mother and I recently read “Defend Your Life.” We both really enjoyed it and were surprised how much vitamin D3 can affect health. This book touches many aspects of life including the need for animals and birds to get their D3. A fascinating read!

ss_amazon_bannerGreat Way To Learn About Vitamin D3!—DC
This book provides a wealth of information about Vitamin D3; what it is and what it can do to improve your health in a number of areas, including cancer prevention, with solid medical proof and insightful personal comments. It is a valuable reference guide that you can read from cover-to-cover or use to look up particular medical conditions that are discussed in short easy-to-read chapters.

It is a very accessible read that gives you valuable information on a vitamin that has had a lot of attention in the past few years. Vitamin D3 is important and it is wonderful that this author has taken it upon herself to provide the latest research and recommendations to her readership. I read her book and although I did know something about vitamin D previously — I am know actually taking it daily and look forward to improving my general health. The book will be of interest to anyone who is keen on health or who has a particular related ailment and wants to find a remedy. Hippocrates, the founder of modern medicine, said; “If you want to cure yourself of a particular ailment go to the local market and ask people who have found a remedy to such a problem and then copy what they have done.” Sounds simple but we often forget to rely on the advice of people who have found what actually works. It was helpful in the book to read that the author used herself as a test project and found what worked — Vitamin D3. Happy health everyone.

I was unaware of the significant positive impact adding D3 to my vitamin regiment. I’m currently going through chemotherapy treatment and I attribute minimal adverse side effect due to my D3 intake. I will continue consuming D3 after treatment and have introduced it to my family and friends as an easy preventative for many illnesses.

Thank you Susan Rex Ryan for providing us with such an easy to read and informative book. You are helping us all Defend our Lives!

My wife read the print version of “Defend Your Life” when it was first released. She raved over this vitamin D book and encouraged me to read it but I am a Kindle kind of guy.

I thoroughly enjoyed this well written, comprehensive insight into Vitamin D3. I ran to check my multiple vitamin to see if I was taking D3. Most impressive was the author’s depth of knowledge about Vitamin D3. The book was easy to read and most importantly the author made the medical jargon easy to understand.
