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.

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.

Vitamin D was first studied to improve bone health and eradicate rickets. Almost every doctor is aware that vitamin D is important for skeletal health. There are thousands of studies that back up this point. But what have we found through our D*action data? Any differences?

One of the most common questions we receive is how much vitamin D should I take to get my serum level to the desired range (40-60 ng/ml)? There is no simple answer, no magic bullet, as everyone's body is different. But here is the information you need, from our D*action data, to help you find a starting point to optimize your vitamin D level.

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.

The Protect our Children NOW! project launches on April 7th, 2015, to implement vitamin D testing and supplementation of pregnant women as standard of care.

A study was recently published that showed a U-shaped curve with respect to vitamin D serum – meaning that upper levels of vitamin D (50 ng/ml) could be harmful for disease or mortality. Read GrassrootsHealth scientists’ comments and review papers which refute this study.

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.

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.
