Thank you for being a part of GrassrootsHealth, whether you started out with us at our first seminar in December of 2008, or just found out about us today, we appreciate your support and your own efforts to spread the word about vitamin D.

Did you know that adequate vitamin D can not only support good oral hygiene but also heal existing cavities? And would it surprise you to learn that the vitamin D level of a mother will affect the oral health of her children? Read more about vitamin D and diet for oral health, and get the latest on serum vitamin D levels of summer lifeguards.

This week we are honored to announce a new paper that clearly shows the >50% reduction in risk of preterm birth with a vitamin D serum level of at least 40 ng/mL from a randomized controlled trial done by Hollis and Wagner. We realize that many of you reading this are not pregnant. But... do you have children? Grandchildren? Think about the importance of this information. Could you help spread the word?

As we enter the winter here in the Northern Hemisphere, it is important to be aware that over the next several months, the sun will not be a good source for vitamin D. This is our Vitamin D Winter. To learn more, listen to our featured video of the week, sunshine calendar, and other information featured in this newsletter.

We are creating a deficiency by misunderstanding and, lack of knowledge. Key Fact: Our bodies' vitamin D production was programmed to be primarily through the skin, from sunshine. But can you get the amount of vitamin D you need from sun alone, and if so, how?
October 21, 2015
At this time, we don't have food sources of vitamin D that provide enough to meet our daily needs. This is changing, however. While certain food sources can contribute significantly to vitamin D status, it is likely that vitamin D supplementation will remain key to improving vitamin D status at a population level. The KEY is still to monitor our serum levels with our individual lifestyles. If, indeed, you are able to get your serum level to 40 ng/ml without supplements, go for it!
October 14, 2015
Today is the first of three newsletters that discuss different ways we could be tackling vitamin D deficiency world-wide. This first news is centered around food fortification.
October 7, 2015
A clinical trial led by Joan Lappe, PhD, RN, FAAN, at Crieghton University found that women given vitamin D and calcium were diagnosed with 80% fewer cases of non-skin cancer than women who received a placebo. GrassrootsHealth was given access to the data from the Lappe trial to compare it to the D*action data. Read on for the results of that analysis, as well as a letter from Dr. Cedric Garland, How to Prevent Breast Cancer.

Coming over the next several months, we'll take you along as we launch new research projects which will enlarge our base of scientific support and, provide yet more answers for you. In addition, we will be working on a number of 'Special Projects' with the aim of quick turnaround time for answers that could affect your health actions in the short term. This month, we're announcing our first 'Special Project' ...

News outlets across the globe have been reporting a resurgence of rickets, a disease caused by severe vitamin D deficiency. So much pain could be avoided and children could start off on the right track, if doctors knew that pregnant mothers need to be vitamin D replete and children need it starting their first few days of life.
June 24, 2015
Humans have adapted to sun exposure over many thousands of years and derive numerous physiological benefits from UV exposure in addition to vitamin D. These benefits cannot be derived from vitamin D intake by supplements, and therefore sun avoidance, the recommendation by the US Surgeon General and others, is unnecessarily putting people at risk.
June 17, 2015
One of the most frequently asked questions we receive at GrassrootsHealth is "What is the difference between vitamin D2 and vitamin D3?"

Recently there have been very negative articles in the Toronto Globe and Mail about vitamin D. They are, in part, a reaction to the ad campaign by Pure North S'Energy Foundation, a Canadian non-profit organization trying to convince Health Canada and the Institute of Medicine (IOM) to reconsider the RDA. Here we include an overview of the latest, and what our scientists have to say.
March 25, 2015

March 11, 2015
Read about how GrassrootsHealth is implementing CHANGE - through the Protect Our Children NOW! program, launching in South Carolina next month, and through the successful publication of our letter in response to a paper from Paul J.

GrassrootsHealth collaborated with Dr. Carol Wagner of MUSC and other researchers to publish a new paper that demonstrates 1) maternal vitamin D status closest to delivery date is more significantly associated with preterm birth and 2) participants with a serum 25(OH)D concentration of at least 40 ng/ml in the 3rd trimester had a 47% reduction in preterm birth when compared to those with a concentration less than 40 ng/ml.
January 21, 2015
Our focus has always been that 20 ng/ml was not sufficient. It turns out that there's an even more serious problem: a review of the IOM's statistical methods shows that they were not correct - 600 IU/day will not get 97.5% of the population to 20 ng/ml. Instead it will only get 50% of the population to that level. More on that, and, an exciting upcoming webinar with the Organic & Natural Health Association.

The mainstream medical field thinks of vitamin D only for bone health but we want them to broaden this perspective to include proper cell growth and healing. Dr. Bruce Hollis demonstrates why treatment of vitamin D for these two things are vastly different - how vitamin D is absorbed into the system, used, and then stays in the system to continue to heal.
