We are still in love with vitamins a century after they were discovered, with half the US and UK population taking a supplement. Vitamin D – the sunshine vitamin – is the favourite and is believed to have the most proven benefits. Governments, including the UK government, have said that the evidence for vitamin D’s health benefits is so overwhelming that every adult should take it as a supplement for at least six months of the year.
It was first used to cure rickets in Victorian children living in urban poverty and is now routinely given to prevent and treat brittle bone disease (osteoporosis) and fractures. It has been associated with a reduced risk of over a hundred common diseases in observational studies, ranging from depression to cancer.
The largest ever clinical study on the benefits of vitamin D in preventing fractures is now reported in the BMJ, with over 500,000 people and around 188,000 fractures from 23 cohorts from many countries. As vitamin D levels are strongly influenced by genes, the researchers used genetic markers for vitamin D blood levels (called Mendelian randomisation or MR) to avoid the normal biases of observational studies, such as confusing cause and consequence of disease and the effects of other related health behaviours (so-called “confounders”).
The results showed no association between vitamin D levels over a lifetime and the risk of fracture. This latest study contradicts the UK government’s recent view, but not a host of earlier clinical trials.
In 2014, a review and meta-analysis of 31 vitamin D supplement trials found no effect on all fractures. Much of our strong belief in the benefits of vitamin D came from studies of supplements in care homes in the 1980s, which were never replicated and were probably flawed.
In a more recent meta-analysis of 33 randomised trials of over 50,000 older adults, supplementation with calcium or vitamin D had no effect on the incidence of fractures. There were also no clear benefits on muscle strength or mobility.
So, if all the data points to vitamin D failing to prevent fractures, why worry about all the people with low blood levels of the vitamin? Vitamin D deficiency has become a modern epidemic with a fifth of the UK and US populations reported to have low levels. Will they be more susceptible to other diseases and cancer?
No consensus on deficiency
There is little agreement on what vitamin D deficiency is. Deficiency levels are arbitrary with no international consensus and confusion caused by different units in the US. A “normal” level can vary from 50 to 80 nanomole per litre of blood, but recent studies suggest 30nmol is quite enough.
While clinical deficiency (<10nmol) is often clear cut, wrongly labelling millions of people as vitamin D deficient causes stress and over-medicalisation. Most people assume calcium and vitamin D are safe, and the more you take the better. My clinical practice changed when studies showed calcium supplements, as well as being ineffective against fractures, may cause heart disease. Prescriptions are now dropping.
Vitamin D is fat soluble, so high levels can build up in the body. While recommendations for supplements are usually with modest doses (10 micrograms or 400 international units (IU)), these will inevitably be overdone by some people taking other sources in cod liver oil tablets or in fortified milk, orange juice or bread. More worrying, people increasingly buy high-dose supplements of 4,000-20,000IU on the internet.
Patients with very high vitamin D blood levels (over 100nmol) are becoming routine in my clinic and elsewhere, and toxic overdoses are increasingly being reported. Several randomised trials have shown that patients with high blood levels or taking large doses of vitamin D (above 800IU) had an unexpected increased risk of falls and fractures. Vitamin D is far from safe.
It can no longer be recommended for use in other conditions; the vast majority of the positive published studies in 137 diseases were reviewed as spurious. It was widely believed that vitamin D supplements prevented cardiovascular disease, but meta-analyses and large-scale genetic MR studies have ruled this out.
We have created another pseudo-disease that is encouraged by vitamin companies, patient groups, food manufacturers public health departments and charities. Everyone likes to believe in a miracle vitamin pill and feels “they are doing something”.
Vitamin D, despite its star status, would not be called a vitamin today, as the doses needed are too large, the body can synthesise it from skin, and it is a steroid precursor. Instead of relying on this impostor, healthy people should get vitamin D from small doses of sunshine every day as well as from food, such as fish, oil, mushrooms and dairy products.
We should also trust that thousands of years of evolution would cope with a natural drop in vitamin D levels in winter without us snapping our limbs. About half the population take vitamins daily, despite zero benefits, with increasing evidence of harm. The worldwide trend of adding unregulated vitamins to processed food has now to be seriously questioned.
While vitamin D treatment still has a rare medical role in severe deficiency, or those bed bound, the rest of us should avoid being “treated” with this steroid for this pseudo-disease and focus on having a healthy lifestyle, sunshine and importantly save your money and energy on eating a rich diversity of real food.

This updated edition has a fascinating new look at diabetes as an evolved defense to freezing damage in winter gone out of control
144+ Pages of Fact-Packed Science Based Information-But FUN to read-
Upon realizing that taking 4,000 IU of Vitamin D3 a day was not enough for me, I decided to embark on a "dangerous" experiment that directly contradicted everything MD's had told me for years:
” DON'T TAKE TOO MUCH VITAMIN D IT IS DANGEROUS!”
I started taking 20,000 IU a day-50X times the recommended dose of 400 IU a day.
After about 4 months upped the dose to 50,000 IU a day or 150X the old recommended “safe” dose I then boosted it to 100,000 IU a day or 300 x TIMES the old maximum safe dose!
What happened over these last 10 months? Did I die? get sick? No! Just the opposite!!
High dose Vitamin D3 therapy over the last year-CURED ALL MY CHRONIC CONDITIONS-SOME THAT I'D HAD FOR 20+ YEARS!
1.A painful snapping hip syndrome which I had been suffering from for 23 years and no Dr could help me-It is now 100% gone. No pain and NO SNAPPING!!
2.Yellow fungus infected toenails (under the nail)- I tried everything over 20 years and nothing worked-10 months of high dose Vitamin D3 and they are clear as a bell! 100% cured.
3.A knobby bone spur on my elbow that made me look like Popeye the sailor man-It has now 100% dissolved and my elbow is back to the way it used to be 20 years ago.
4.Painful , clicking, popping, stiff Arthritic shoulders that prevented me from even throwing a ball from home plate past the infield. A condition I’ve had for 15 years. Gone. No more popping snapping or clicking and I can throw the ball twice as far .
5.A ganglion cyst that persisted on my wrist for over 5 years has shrunk from the size of half a golf ball to the size of a pea and now it is rock hard ,painless, and shrinking.
6.A small subcutaneous cyst on my face that had not gone away for 20 years –now gone!
7.AND-Without even trying my weight has dropped by 25 pounds from 204 to 179.
This book tells you detailed results of my experiment, dangers to avoid, and also discusses a simple and elegant new theory that suggests how High Dose Vitamin D3 therapy Should help PREVENT OR CURE all the epidemics of disease and health issues that have been plaguing us since the 1980’s when Doctors started warning us to stay out of the sun and always use sunscreen. This has created the huge epidemics we see today of Obesity, Autism, Asthma, and many others!
The theory is simple-Vitamin D3 is a hormone that your skin makes when you sit in the sun, it is not a vitamin it was just mislabeled when it was discovered. When your Vitamin D3 levels are low, your body gets you to prepare for winter by overeating, slowing you down to conserve energy, and even making you depressed to keep you housebound. Interestingly it is this same drop in Vitamin D3 levels that signals a bear to start hibernating!
If your body expects famine-like conditions caused by winter to be likely- it will conserve your critical resources for the future. This leads to what I call the Incomplete Repair Syndrome which in turn causes most of the diseases humans face other than spontaneous gene mutations that cause syndromes and diseases caused exclusively by aging. High D3 can be used to prevent or treat a huge number of diseases MS, asthma, 17 kinds of cancer, lupus, arthritis, heart disease, obesity, depression, Parkinsons+many more...
This IS the better mousetrap! Most MD's get just a basic 4 years in Med School, then work to earn not learn. I've researched diseases and aging for 20+ years, with a 10 year stint where I spent 12 hrs/day everyday in the Northwestern Med School's library just reviewing clinical and scientific studies! .I've had 3 major papers published; the journal has 5 Nobel Prizes between the editors. And described my papers as extremely exciting and of major importance

You might be surprised to learn that all these problems may be the result of a deficiency of one substance that has been misunderstood since its discovery in 1939. That substance is vitamin D3.
While it is called a vitamin, D3 is really a hormone. It was first used to treat a childhood bone disease called rickets. And, nearly all the research on the benefits of vitamin D3 has been done at doses that are 80 times lower than the optimal doses described in this book. This ground-breaking book is your opportunity to regain your health quickly, safely and easily.
In The Optimal Dose, he reveals how vitamin D3 saved his own life when all else failed and explains how this essential vitamin is key to finding answers to your own health questions and challenges.
