Vitamin D3, which is technically a prehormone, has a whole host of benefits. This invaluable substance has a role in preventing or treating many diseases including cancer. Below you’ll find a letter I received as being a participant in a Vitamin D study, the results of which were published in the International Journal of Cancer Research and Treatment
GrassrootsHealth New Research Publication in the Anticancer Research Journal, 2/21/2011
Dear Michael,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!”

University of California RiversideKey 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!
