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.
This is the type of "tidal wave" that I was hoping for when I wrote my book The Vitamin D Revolution. I am delighted to see that a revolution is really starting to happen with awareness about vitamin D.
In spite of all these studies on vitamin D, only one prospective interventional trial is large enough to look at the benefits and risks of vitamin D from multiple chronic diseases. This study is called the VITAL study. VITAL stands for "Vitamin D and Omega-3Trial " This trial will test the benefits of giving patients 2000 IU of vitamin D per day in 20,000 American men and women over the following five years.
As I've said many times before, in my opinion there is no reason to wait five more years to start taking vitamin D. We know that there is absolutely no harm and most likely a lot of benefit from optimizing your vitamin D level.
