Confusing and conflicted data dominate the nutritional supplement landscape concerning the scientifically proven benefits of vitamin D. Many books claim vitamin D supplements are "miracles" or "wonder pills." But, such is far from the scientific reality of failed and disappointing studies conducted on so-called vitamin D products. All studies presented in this book are well referenced and articles are duly credited. This book is the leader in presenting scientifically accurate data and serves to debunk the sea of lies facing the general public regarding a plethora of so-called vitamin D products. Basically, there is "no truth in advertising and "anything goes," because none of the dietary supplemental products are government regulated for quality or accuracy of contents and dosage. Sadly, profiteers will "Tell you anything, to sell you anything." Profit is the underlying motivation for the false claims regarding vitamin D. Is there a serious down side to excessive doses of vitamin D products? Find out if suggestive evidence exists that high vitamin D concentrations are linked to an increased rate of falls and risk of hypercalcemia in chronic kidney disease patients not requiring dialysis. Is there justification for prescribing vitamin D supplements to prevent myocardial infarction or ischemic heart disease, stroke or cerebrovascular disease, cancer, or fractures, or to reduce the risk of death in unselected community-dwelling individuals? Is it wise to prescribe vitamin D supplements to healthy adults to reduce the risk of diseases or fractures? Dr. Howes presents the scientific facts surrounding vitamin D. Check it out today! Dr. Howes was the first in the history of Tulane School of Medicine to receive double doctorate degrees in medicine and biochemistry simultaneously. He was the first to complete board eligibility in both general and plastic surgery at The Johns Hopkins Hospital, all in a six-year period. Dr. Howes invented the triple lumen venous catheter, which has been credited with helping save the lives of over 20 million critically ill patients worldwide. His catheter became the number one venous catheter in the world and his name is well recognized in over 100 countries. He received the Harper Award from the American College for Advancement in Medicine and served as their keynote speaker and in 2013, he was the first to be awarded the Charles Farr award for "excellence in oxidative medicine." Dr. Howes is one of the few physicians and medical scientists that will tell the raw truth concerning the failure of many dietary supplements and point out their potential harm.
