Présentation de l'éditeur

"This information can save your life. Really." -Christiane Northrup, MD, New York Times bestselling author of The Wisdom of Menopause

Many Americans have succumbed to the scare tactics of the dermatological community, and avoid sunlight for fear of skin cancer and premature aging. Therefore, most of us suffer from vitamin D deficiency, which causes daily aches, pains, and fatigue, worsens serious illnesses, and diminishes the quality of everyday life. Drawing on decades of research, Dr. Michael f. Holick reveals a well-kept secret: our bodies need a sensible amount of unprotected sun exposure. The most comprehensive rescriptive book on the market, The Vitamin D Solution offers readers an easy and inexpensive plan to reversing the effects of vitamin D deficiency-and enjoying a substantially healthier life.

Vitamin D Dosage Guidelines from World's Leading Expert on Vitamin D 6 mai 2010
Par T.R. Hammer - Publié sur
Format: Relié
My criticism of Dr. Holick's first book on Vitamin D was that he neglected to provide dosage guidelines. His new book contains Vitamin D dosage guidelines--and lots of them!

Holick has dosage advice for pregnant mothers, children, and adults. He talks about how much he advises his patients to take when they are very low, and how much to take when they have got their levels up to healthy levels. He even says how much he personally takes.

Dr. Holick discusses the different ways Vitamin D can be absorbed -- sun, supplements, food, and Vitamin D lamps.

He also explains how common health problems (obesity); skin color (dark); location (north); season (winter); age (elderly); gut health (poor); drugs (prednisone); and rare diseases interfere with Vitamin D absorption. It is surprising to read he recommends obese people take 2-3 times the Vitamin D of non-obese people. Does the Government do that? No. Why? He does the research and it doesn't.

Holick believes the Recommended Daily Allowance (RDA) of Vitamin D is far too low; it's based on poor outdated research from 50 years ago. Government employees and average doctors are extremely ignorant about Vitamin D, unfortunately. Fortunately, however, they do blood tests for their patients, and then they're converted.

You may not know that the effectiveness of the sun for Vitamin D depends on where it hits your body and how much of your skin is exposed to the sun. Your face is the least effective part at absorbing the sun for Vitamin D; so all those walks in the spring, fall, or winter you might take aren't as valuable as you might think. (I'm thinking of getting a new Vitamin D lamp that Holick has tested.)

The good news this book gives is it doesn't take a long time or cost a lot to fix the very common health problem; rather, it's fairly quick and inexpensive to get your Vit-D level up. In as little as two months through sun (free) or supplements ($25) you could get healthy Vit-D levels. Furthermore, high levels in the summer can take you through the entire winter.

If you already have Holick's first book like I do and are wondering about getting the new one, I suggest you get it. This one has new material because Holick is still on the cutting edge of Vitamin D research. You can never know too much.

I'm not sure Holick mentioned it (don't recall reading it in his book, and it's not listed in the Index), but there is some research that indicates Vitamin A taken with Vitamin D can lower Vitamin D absorption.

Despite being so knowledgeable about Vitamin D and ahead of just about everyone, Holick is behind on the research about bright light boxes for circadian rhythm and SAD therapy. New research has shown they can cause eye damage. It can takes years before the blindness comes. The elderly are at greater risk. Green light therapy has been shown to be safer than bright light and blue light but just as effective. (The military did its own tests and is now using green; Google green light therapy to learn more.)

An authoritative reference on the nutrient that could revolutionize healthcare 26 avril 2010
Par Rich Blumenthal - Publié sur
Format: Relié Achat vérifié
Learning about vitamin D from Michael Holick is like learning the art of magic from Harry Houdini. Greatly reducing the likelihood chronic degenerative disease such as cancer, heart disease, stroke, and diabetes (and many more) is easier than you think once you know the secret. Although no supplement, diet, exercise, or lifestyle change can completely eliminate risk, The Vitamin D Solution will give you incredibly powerful, life-altering information that's as easy as getting some sensible sun exposure or popping a safe, inexpensive pill.

Michael Holick, the world's leading expert on vitamin D, is your guide on this journey of discovery. His pioneering efforts in that field go back to his days as a graduate student when he synthesized the active form of vitamin D, finding it to have extraordinarily powerful therapeutic effects. His contributions as both a scientist and practitioner have made profound advances in every aspect of vitamin D research. Dr. Holick has been a tireless researcher, advocate, author, educator, and legendary lecturer for over 30 years. He stands as the most prolific author of articles published in peer-reviewed medical journals including the prestigious New England Journal of Medicine.

I have a few predictions. The latter 2/3 of the 20th century will become known as the dark ages, when they demonized the sun, a situation that led to untold suffering and literally millions of largely preventable deaths. Dr. Holick will emerge as a central figure ushering in a new age where sunlight and vitamin D (along with other well-known lifestyle changes) eradicate millions of needless cases of chronic disease. Mainstream medicine will embrace the preventive and therapeutic power of vitamin D, and for his pivotal role bringing about the sea change in the practice of medicine, Dr. Holick will earn a well-deserved Nobel Prize. You heard it here first.

Dr. Holick contends that vitamin D deficiency is the most common medical condition in the world. Being both a researcher and clinician gives him tremendous insights to fortunate readers of this excellent reference. The book opens with two hypothetical pre-teen girls, one living in poverty near the equator and the other living a typical middle class American lifestyle. The list of diseases and medical conditions that are far more common for the middle class girl is shocking. It is no longer debatable that sunlight and vitamin D play major role in preventing a long list of serious chronic diseases, a reality that is becoming more and more accepted by the medical community.

Ideally you should read the entire book in linear fashion, but even if you open the book to random pages you'll find useful information everywhere, such as a new model of cancer that can't grow in a vitamin D-rich environment (page 87); the role of vitamin D in preventing Parkinson's and Alzheimer's (page 140); how vitamin D repairs pancreatic beta cells and thus is an important tool in the fight against diabetes (page 97); the only accurate way to test for vitamin D deficiency (page 147); and a new perspective on what killed the dinosaurs (page 28). I can't go over all 300 pages in this review but I hope you get the idea there is a lot of important information we all need to learn. The book is easy to read, devoid of oppressive jargon, easily accessible to the curious layman, covers the subject reasonably well, and would make an extremely good addition to the library of anyone who understands that good health comes from wise lifestyle choices. For these reasons, I am D-lighted to give the book a solid 5-star rating and the heartiest possible endorsement.

One of my favorite anecdotes involves a baby gorilla on the brink of death when Dr. Holick was called in to help. Classic symptoms of rickets led to an infusion of 5000 IU of vitamin D per day. The patient staged a remarkable recovery and Dr. Holick was the guest of honor at Kirmani's first birthday when she was clearly a happy, healthy, active gorilla. When Dr. Holick presented this story at a vitamin D conference in San Diego (complete with before and after photos) the audience burst into applause. I was there and can attest it was a magic moment. Read about it on page xxiv.

Another amazing story involves a lawyer who supplemented with vitamin D, developed symptoms of overdose, and called Holick to state he was planning to file a malpractice lawsuit. Dr. Holick had the lawyer send him the bottle of capsules which he thoroughly tested, only to find that due to a horrific manufacturing error the lawyer was actually taking over 1,000,000 IU a day. So instead of facing a grueling lawsuit, Dr. Holick acquired an important body of data since vitamin D overdoses are exceedingly rare. (Read about it on page 47.) The lawsuit was dropped, the lawyer quickly recovered, and we have valuable information about diagnosing and treating vitamin D overdose. Everyone wins.

Are there any negatives or downsides to this book? All my comments speak to the controversial nature of vitamin D where experts disagree in many areas. For instance, Holick states that D2 is equally as effective as D3 (page 217), yet the vast majority of researchers state that D3 is more bioavailable and stays in the system longer. On page 251 Holick states magnesium is unrelated to the uptake of vitamin D, which directly contradicts other experts. Holick generally avoids the details of studies that lead to various conclusions, which could be viewed either as a plus (easier to read) or a minus (lack of supporting evidence). There are more like this but I don't want to dwell on minutae. No two vitamin D experts see eye-to-eye on all aspects of this complex, confusing, confrontational subject. But this book contains so much solid, essential information it would be recommended reading for anyone even if they have minor disagreements here and there.

On page 214 Dr. Holick touches on a subject of utmost importance: Why can't the Institute of Medicine get it right when determining recommended vitamin D supplementation levels? The problem lies primarily in the guidelines of evidence-based medicine that only allows input from research reported in peer reviewed medical journals. Because pharmaceutical companies have no incentive to support research costing tens of millions of dollars to prove the value of an extremely inexpensive supplement, vitamin D studies tend to be of the lower-credibility observational type. Because medical science views this as a lack of compelling evidence the industry is hesitant to actively endorse vitamin D, and we all suffer as a result. I wish this flaw was exposed in a more forceful way but I'm glad at least was mentioned to give readers of this book some valuable insights. As a side note, The Institute for Functional Medicine promotes a system that sidesteps the flaws inherent in evidence-based medicine, and Dr. Mark Hyman, their most visible spokesman, provided a strongly supportive testimonial appearing on the back cover.

Here's the good news: You don't have to wait for the Institute of Medicine, the medical profession, or even your family doctor to jump onboard in order to benefit from the magic of vitamin D. However, you need to do your homework and that's where The Vitamin D Solution comes in. Dr. Michael Holick has done a superb job presenting information that will help you achieve optimal health. Read, it, study it, think about it, understand it, and most importantly, put it into action to get your 25(OH)D level above 50 ng/mL. (For most people that requires daily regimen of about 5000 IU.) The life you save may be your own.

Great details on benefits of vitamin D 3 avril 2010

After reading 7 books and over 2,000 articles on vitamin D during the past 4 months I still had many notes to take when reading this excellent book. Sometime I took the notes were because Dr. Holick presented the information in a way that I could finally understand, and in other cases the information was new to me. Three pages of my notes are at VitaminDWiki dot com. The Power of Vitamin D probably provides a better first book on this subject.

Get Vitamin D Tested, Soak In The Sunshine, & Supplement To Fill In The Gaps 6 octobre 2010
Par Livin' La Vida Low-Carb Man - Publié sur
Format: Relié
It's no secret that despite all the modern technological advances in pharmaceutical medications and other disease treatments that are available out there on the market today, our society is still dealing with some of the most debilitating and devastating chronic health conditions we've ever seen in the history of the human race. This oxymoronic position has to leave people scratching their heads wondering what in the world is going on. How can we be so far ahead of the human race that existed just a half century ago and yet now we're falling so far behind that generation in terms of living a healthy lifestyle? There are a lot of theories about this floating around out there (including the notion that today's society is consuming far too much sugar and carbohydrates to be healthy), but Dr. Michael Holick thinks he's identified the common culprit that has made us fatter and sicker than ever before-Vitamin D! Yes, everybody and their momma is talking about Vitamin D these days and it's finally getting the recognition is deserves. But as the world's leading expert on Vitamin D studying it for over three decades, Dr. Holick has been on the cutting-edge of promoting the health improvements that people can experience by raising their Vitamin D3 levels for many years and now he's sharing all of his vast knowledge about it with us in his book The Vitamin D Solution: A 3-Step Strategy to Cure Our Most Common Health Problem.

Although it's referred to as a "vitamin," the reality is Vitamin D isn't a vitamin at all. It's actually a hormone that directly impacts so many areas of the body that it just makes sense to get your D3 levels up. Upwards of 200 million Americans are walking around with a severe Vitamin D deficiency and don't even know it. They've been told by well-meaning doctors that they have fibromyalgia, depression, genetic tendencies, and more. But if you check the D3 blood work, I would venture to guess that nine times out of 10 their Vitamin D levels are probably on the low to extremely low end of the spectrum. My own wife Christine dealt with this a few years back when she was experiencing excruciating joint and muscle pain as well as fits of depression and panic attacks only to find out here D3 came in at a dismal 9 ng/mL! If you don't know what that means, let's just say it's not good at all. She began taking 10,000IU D3 gel caps for a year and was able to raise her levels to 52 ng/mL. Now she has no more joint and muscle pain and she came off of a 10-year reliance on Paxil to control panic attacks. That's the miracle of Vitamin D and the stuff is dirt cheap, too! Yes, knowing your Vitamin D levels is a big deal.

So how in the world did we suddenly become so Vitamin D deficient? Lack of sunlight exposure, poor nutrition, and inadequate or severely lacking sources of it in supplements and fortified foods (like milk) are most of the problem. But regardless of how we there, the good news is there is a solution just waiting for those people who are dealing with any number of health ailments that cannot be explained by modern medicine or the symptoms are simply being masked by risky drug therapies. What is it? GET MORE VITAMIN D! How do you do that? Well, it depends on where you live, but sun exposure may not be enough if you live north of Atlanta or San Diego and you can't get enough of it in the foods you consume either (it would take 50 egg yolks to get adequate amounts of Vitamin D-talk about an eggfest!).

Dr. Holick says he prefers you get your Vitamin D from the sun first and foremost and to only use supplementation as an added aide to get your levels increased to where it needs to be. What level do you want your 25-vitamin D level to be? Ideally between 30-100 ng/mL according to Dr. Holick with the sweet spot landing in the middle around 60-80 ng/mL. Below 20 ng/mL is considered deficient while below 30 ng/mL is insufficient. Again, upwards of two-thirds of the American population is Vitamin D deficient right now. This is directly impacting health to the extent that ailments like osteoporosis, heart disease, cancer, autoimmune diseases, insomnia, arthritis, diabetes, chronic pain, psoriasis, autism and so much are likely a direct result of these deficiencies in something you can buy a big bottle of for around $10 at Sam's Club along with adequate sunlight exposure.

In The Vitamin D Solution, Dr. Holick includes a "self-test" in Chapter 7 to see what level of deficiency you may be experiencing. Things like sun exposure, where you live, what vitamins you consume, what kind of foods you eat, what beverages you drink, your nationality and race, your age, whether you are overweight or obese, your pain tolerance, your energy and strength, medications you are taking, and specific diseases you are dealing with will help you know even before having a Vitamin D blood test conducted whether you have a susceptibility to being deficient. Of course, the best thing you can (and should) do is get tested. What you need to have run by your doctor is the 25-hydroxyvitamin D test, aka the 25(OH) D test. It will show you how much circulating Vitamin D you have in your body. Beware of doctors ordering the wrong test and thinking your Vitamin D levels are fine. And don't get fooled into filling that useless prescription for a once-a-week 50,000IU Vitamin D2 pill that costs an arm and a leg (although Dr. Holick believes it will help "fill an empty Vitamin D tank!"). What you want is D3 which is very affordable from virtually any drugstore, pharmacy, or Wal-mart in varying doses as low as 100IU capsules to 5000IU gel caps. Get tested and respond accordingly!

The good news Dr. Holick brings with this book is that there is a real "solution" to your Vitamin D deficiency that is as easy as setting aside time for deliberate sun exposure, making sure you are consuming adequate amounts of calcium in your diet so that the Vitamin D can be maximized for health, and making up the difference in your Vitamin D needs through supplementation. And lest anyone, medical professionals especially, warns you of Vitamin D toxicity, Dr. Holick is quick to note that your body cannot manufacture a toxic level of Vitamin D from simple sun exposure no matter how much sun you get. And supplementation isn't a problem unless you are taking super-high doses well above 10,000IU for longer than six months. The bottom line is to make sure you are taking every measure possible to increase your D3 levels to ward off any potential negative effects on your health.

The Vitamin D Solution is arguably the most comprehensive book on the subject of Vitamin D today and Dr. Holick certainly knows from whence he speaks. He's been trumpeting the case for Vitamin D awareness for a very long time and is just now receiving the critical acclaim he rightly deserves. My favorite part of this book is in Chapter 13 which is the "Q&A" session that answers anything and everything you can possibly think of regarding the subject of Vitamin D. He also provides a resource guide for finding good sources of Vitamin D supplementation as well as a bibliography of other Vitamin D experts and researchers he cites in support of the conclusions he draws throughout his book. Needless to say, I'm a big fan of Vitamin D and the positive effects it can have on your health. My own Vitamin D levels increased from 42 ng/dL to 68 ng/dL taking 10,000IU D3 gel caps in just six months, so it is indeed possible to overcome many chronic health problems with a concerted effort to make it happen naturally. Isn't it time to stop suffering needlessly from Vitamin D deficiency?

[2012 WARNING: Until 2012, none of the books on the benefits of Vitamin D3 warned about the need to also take vitamin K2! I have to wonder how all these self-claimed vitamin D3 experts, who also claimed so many successes, were ignorant that vitamin A (it seems most of us are deficient in this vitamin too), vitamin D3 and zinc must come together in balanced proportions. If you take calcium and vitamin D but are deficient in vitamin K, you may be increasing the risk of a heart attack (although Holick says there is inadequate research for this claim).

Vitamin K is essential not only for preventing potentially deadly blood clots but also for bone building (including delaying tooth decay) and maintenance. Perhaps most important - K has powerful anti-cancer effects. It is known to be helpful for cardiovascular disease, varicose veins, brain health problems, including dementia and even prevents infectious diseases such as pneumonia. Some claim that most people need daily vitamin D3 of at least 2000 IU with 3000 IU of vitamin A and 100mcg of vitamin K2. The synergy between them is vital as there is evidence that the safety of high dose vitamin D is dependent on vitamin K, and that vitamin D toxicity (although very rare with the D3 form) is actually caused by vitamin K2 deficiency.]

Of the 8 books on vitamin D I've now read, this is now my favorite pick. It's practical and he has a way with words: "vitamin D deficiency is our most common health challenge globally", "vitamin D is in a class by itself; its far-reaching effects on the body are aligned with how hormones act to influence metabolic pathways, cellular functions, and the expression of myriad genes", "in some respected medical circles, sunlight is being described as a 'wonder drug'". At 300 pages I also found it thorough and I specially liked the straightforward explanation that sunshine, when it's strong enough, is always better than supplementing with Vitamin D.

Dr. Holick is a professor of medicine, physiology and biophysics at Boston University Medical Center in the USA who has studied vitamin D for over 30 years and has received awards relating to health research and nutrition. He explains that he lost his teaching position as a Dermatologist in 2004 because he refused to agree with his boss and with the Dermatology profession generally that even the tiniest amount of UV/sunshine is bad for us. Unlike most of the other books, which recommend only vitamin D3, he says that either vitamin D2 or D3 is fine.

Of the other books, "The Vitamin D Revolution" by Soram Khalsa was previously the one I preferred while "Vitamin D Prescription" by Eric Madrid is also good and of the 2010 books "Vitamin D" by Rona and "Power of Vitamin D" by Zaidi are both brief but quite good. "The Vitamin D Cure" by James Dowd is not basic, comprehensive or practical. Then there is "Vitamin D" by Michael Merrill which was too brief and simply inadequate. At the other extreme is the comprehensive but somewhat technical "Sunshine and Vitamin D" by Frank Murray - mainly brief compilations of hundreds of studies but no practical guidelines, so not really suitable for the layman who wants to experiment with high-dose vitamin D.

There are more and more books - and a great deal of media fanfare - on the recently discovered almost miraculous properties of vitamin D. It's also worth noting that over a decade ago several books were already lauding the much-overlooked benefits of sunshine, the best way to get vitamin D, although the further away from the equator, the less effective. Anyone living above the 35th parallel is highly likely to have a sunshine/vit D deficiency that can also lead to many common symptoms. (Those who react badly to Vitamin D and/or sunshine may have a rare disease called sarcoidosis.)

According to most of these books, the vast majority of us are deficient in vitamin D whereas adequate levels can alleviate chronic pain, stroke, osteoporosis, heart disease, cancer, autoimmune diseases, depression, arthritis, diabetes, gum disease, psoriasis, fibromyalgia, autism and much more. Perhaps it's just my cynicism from decades of reading endless books singing the praises of so-called miracles such as DMSO, MMS, DHEA, vitamin C, magnesium, iodine, omega 3 EFAs, breathwork, oxygen therapy, hydrogen peroxide, water, thyroid hormone, adrenal hormone, liver cleanses, detoxes, fasts, exercise, neutralising electromagnetic stress, juicing, mangosteen, noni juice, superfoods, organic foods, wholefoods, celiac diets, dairy-free diets, veggie diets, protein diets, carb diets, food combining, acid-alkaline balancing diets, Glycaemic Index diets, high fibre diets, raw food diets, candida/fungus elimination, parasite cleansing - oh dear, the list of my gullibility seems endless.

Yes, I've tried all of these; yes, thoroughly and sometimes repeating them in various combinations and on each occasion with enthusiasm and bright-eyed hope but I saw no measurable benefits. "Trick and Treat" by Groves explains in detail just why so many of my efforts were doomed. Nowadays, when I read about health wonders, I wonder how many claims of success are made up or at least tweaked - and I wonder what proportion of actual patients were successful in any way, much less miraculously so, as is always claimed by books touting single strategies.

I was startled to learn in this book that about a third of the population has kidney disease (which never gets diagnosed until too late and allegedly little can be done for it apart from horrible treatments like dialysis) and that about the same number are obese (hello... anyone making a connection here?) and that their bodies may not be able to produce enough activated vitamin D: as compared to the non-obese, vitamin D levels rose only 50% as much in the blood levels of the obese when using a tanning bed or getting a dose of 50,000iu of vitamin D. The obese get a lot of blame for what is not actually their fault: studies now show that calcium also plays a key role in reducing obesity (elsewhere I have seen studies showing large weight loss in about 30% of obese women who take both calcium and vitamin D).

Holick is the only author who makes it clear that there are many whose bodies have difficulty converting vitamin D into the active form, such as older people or those who have a wheat/gluten intolerance (much more common than realized). Based on my personal experience of taking 10,000iu daily of vitamin D3 for 6 months (but Rona's book mentions Norm Shealy, a physician who has taken 50,000iu per day for 18 months), I'm not convinced that vitamin D supplementation of the non-prescription kind is a panacea, as so many of the books are claiming - and I am not convinced that all these authors got the unanimously fantastic results they allege. While I believe that vitamin D supplementation at 5,000 ius daily is beneficial, too many single-strategy books have a way of sounding a little overzealous, attributing every malady to whatever deficiency they're tackling and proposing it as the magic solution across the board. Further, not one of these books on vitamin D explains that vitamin D cannot work without magnesium, and that anyone with a chronic health issue is magnesium deficient, as explained in "Treatment Essentials" by Dr Mark Sircus.

LATER NOTES: I eventually was diagnosed, by a metabolic specialist, with serious adrenal fatigue and serious low thyroid issues. The thyroid issue had been getting worse for 2 decades, whilst "standard" medicine denied I had either, repeatedly assuring me all their tests "proved" this. Turns out you have an 80% chance of one or both, if you have a chronic health issue. Visit the Broda Barnes Foundation website for a list of the few thyroid-sympathetic doctors in your state: click on the "educational info" button on the left. It's also worth knowing about "The Calcium Lie II" an intriguing book plausibly claiming to explain the root cause of most illnesses and which shows how taking calcium with vitamin D is actually dangerous and that the increased cancer and medical problems related to "vitamin" D hormone deficiency are more likely related to D hormone suppression from intracellular calcium excess thus leading to adrenal suppression with a resulting increase in illnesses.
