A new study has been published in the Archives of Internal Medicine looking at vitamin D levels and brain function. The study was led by David Llewellyn, Ph.D. of the University of Exeter in England. His group evaluated elderly patients' brain function 3 times over a six-year period.

The researchers tested overall cognition which includes thinking, learning, and memory. They also tested attention and executive function. Executive function is the ability to plan, organize and prioritize.

The results of the study showed that those patients who were deficient in vitamin D were 60% more likely to have a significant decline in overall cognition and 31% more likely to have declines in executive function, than those who had sufficient vitamin D levels. A significant aspect of this study is that none of the elderly patients had any signs of dementia at the beginning of the study.

In a new article in Endocrine Today, Anthony Norman, MD, distinguished professor of biochemistry and biomedical sciences at the University of California, Riverside has said that "it is now widely appreciated by vitamin D scientists that 50% of people in North America and Western Europe are vitamin D insufficient. As far as the rest of the world, He went on to say in another interview  that "Elsewhere, it is worse, given that two-thirds of the people are vitamin D-insufficient or deficient. It is clear that merely eating vitamin D-rich foods is not adequate to solve the problem for most adults."

He also stated that "There is the emerging view that the relative daily intake of vitamin D should be increased from the currently recommended 200 IU, 400 IU, 600 IU per day to a significantly higher level of 2000 IU to 4000 IU per day. He further stated "Already, several studies have reported substantial reductions in incidence of breast cancer, colon cancer and type 1 diabetes in association with adequate intake of vitamin D, the positive effect generally occurring within five years of initiation of adequate vitamin D intake."

The amount of information coming out about vitamin D is exploding! There are currently more than 1000 ongoing studies looking at the benefits of vitamin D listed on clinicaltrials.gov.

From 1995 to 1999 the average number of papers with the term "vitamin D" in the title or abstract was about 700 to 900 annually. In 2009 alone over 2400 papers were published on vitamin D.

Prominent vitamin D researcher Anthony W. Norman M.D., who is a distinguished professor of biochemistry and biomedical sciences at the University of California, Riverside was quoted as saying "There has literally been an explosion of new data on vitamin D".
In his Endocrine Today blog Michael Kleerekpoer, MD, estimated that there are over 30,000 blood tests drawn for vitamin D done by laboratories every month in America.

I have been saying it for a long time but now a study has proven it. A lot of the Vitamin D at the health food store has the potency that is on the label and lot of it does not! All the labels are pretty and I personally would have no way to decide which brand to buy at the store.

Now an amazing study has proven this. Dr C. Eckstein and colleagues have published an article entitled "Vitamin D content in commercially available oral supplements" that was done at the Consortium of Multiple Sclerosis Centers.

They bought 10 different brands  of  vitamin D  at the health food store and online and measured their actual potency and of course compared it to what it was labeled.

The findings are astonishing.

A very interesting article appeared recently in the Financial Times.

The article interviewed Proffesor Reinhold Vieth, a prominent professor at the University of Toronto and one of the major researchers who publishes articles on Vitamin D. In this article, Dr Vieth discussed his frustration that governments are not recommending a higher dose of vitamin D for all their citizens.

This article clearly discusses the three main reasons that higher dose vitamin D is not being recommended by governments..

1) The research that exists is primarily as I have pointed out epidemiological and not the classical double-blind crossover placebo type of study that is required to get the majority of medical organizations to recognize its importance.

2) Lack of money. Most new scientific discoveries are funded by drug company money. No drug company will fund research on Vitamin D because they cannot take a patent out on this naturally occurring substance. Therefore they will not fund research.

3) Most research is done in the "pharmaceutical drug company model". In this type of study, sick people are given a drug to see if it makes a difference to their health condition over time. In the case of vitamin D, we are looking to prove that taken over many years it will PREVENT disease. It takes a long time and a large group of people to look at healthy people and follow what develops in their lives. This is much more expensive and much more time-consuming, than a 6 to 12 month drug trial.

Dr James Sabetta and colleagues  from Yale University School of Medicine, have published yet another article showing the benefit of vitamin D in protecting against colds and other respiratory infections.

This article which just came out followed almost 200 adults and did monthly vitamin D blood levels on all of the patients from September to early January. The patients were followed for the entire study time for developing upper  respiratory infections (common cold or flu).

The findings are completely consistent with what I talk about in my book and here on my blog as well as other articles on Vitamin D and viral infections.
