Dear Deborah,

Congratulations and thanks to absolutely everyone who has participated in and supported this project! According to one of our panel members, Dr. Anthony Norman:

"This paper provides a long awaited insight into a dose-response relationship between orally administered vitamin D3 and the resulting levels of serum 25(OH)D in over 3600 citizens. The results will allow a new definition of high vitamin D dose safety and reduce concerns about toxicity. This is a landmark contribution in the vitamin D nutrition field!"

Key findings:
There were 3667 people's first test data reported on
No suggestions of toxicity were reported even up to intakes as high as 40,000 IU/day (not a recommended amount, however)
It's going to take about 9600 IU/day to get 97.5% (almost everyone) to the 40 ng/ml level. Individual variations however range from 0 to over 50,000 IU/day!
Testing is necessary to determine what the starting serum level is and how to adjust intake
It took 3 tests (1 year) to determine the optimal dose for each individual
The NEW rule of thumb for dosing will be changed. We'll publish a chart for all very shortly. Currently, it is stated that you can increase the serum level by 10 ng/ml with 1000 IU/day. Per our research, this is true only when starting at about 10 ng/ml. If you want to go from 50 to 60 ng/ml, it will take an additional 2000 IU/day (i.e., the rise is only 5 ng/ml for each 1000 IU/day).

Please visit our website, GrassrootsHealth and listen to the interviews with the study's authors, Dr. Cedric Garland and Dr. Robert Heaney. They both speak to the significance to public health of this study.

Another key item that I am very aware of is the public's readiness to 'take charge' of their own health. With this view and the information to make it happen, we are bound to see some very exciting things with own health!

The research article is 'open access' so that everyone can download and read it! Please do so here: GrassrootsHealth Research Article

Again, very, very many thanks to all of you for your participation and support. You are helping change the face of public health! We CAN move to a much more 'preventive' model of healthcare. Please let me know at any time how we can best help.

We do need your ongoing financial support as well, to keep 'spreading the word'. Please consider a donation to Prevent Vitamin D Deficiency for our future health.

Onwards!

He also suggests that Vitamin D may be better absorbed because of the fat( in the yogurt used in the test.)

"We found that daily intakes of vitamin D by adults in the range of 4000-8000 IU are needed to maintain blood levels of vitamin D metabolites in the range needed to reduce by about half the risk of several diseases -- breast cancer, colon cancer, multiple sclerosis, and type 1 diabetes," said Cedric Garland, DrPH, professor of family and preventive medicine at UC San Diego Moores Cancer Center. "I was surprised to find that the intakes required to maintain vitamin D status for disease prevention were so high -- much higher than the minimal intake of vitamin D of 400 IU/day that was needed to defeat rickets in the 20th century."

"Most scientists who are actively working with vitamin D now believe that 40 to 60 ng/ml is the appropriate target concentration of 25-vitamin D in the blood for preventing the major vitamin D-deficiency related diseases, and have joined in a letter on this topic," said Garland. "Unfortunately, according a recent National Health and Nutrition Examination Survey, only 10 percent of the US population has levels in this range, mainly people who work outdoors."

Fascinating information, Deb. Thank you for sharing it.

I did get a kick out of the name Dr. Anthony Norman.

Deb that is a great bit of news and research. It has taken 4 months of dosing at 7k IU per day of D3 to bring my levels up from 17 to the new level of 36 taken just last week.

Congrats, Joe, on getting your D3 levels up. And I'm glad to have your dosing info as a reference point. I was about to have mine tested when the latest flare occurred - I wish I'd had the 'before' and 'after' numbers, but will still find my current levels useful, when I get back to the lab.
