First thing I did when I read the article (found it on Monday before it was posted here) was to jump on the internet and check to see if Sweden fortifies their milk with vitamin D. And of course, yes, they do.

Hard to believe, but in Medpage Today I read:
"Vitamin D is everyone's favorite supplement, but it's getting no love from the authors of a recent analysis. No association was found between vitamin D and a lowered blood pressure, found a large meta-analysis, led by Miles Witham, PhD, from the University of Dundee in Scotland.

The findings received widespread media coverage, and some took the opportunity to call for an end to widespread vitamin D supplementation.

David Agus, MD, for example, was asked by Charlie Rose on CBS This Morning if we need vitamin D. "The answer is no," said Agus. "More and more people are taking it -- it's the second most taken vitamin in the country, behind multivitamins."

Agus then said that patients should challenge their doctors and ask for data if they're told they need to take more vitamin D. "We now have to reassess what is normal," he said. "Nobody should be taking it at the present time, in a normal individual."
Medpage Today is a publication for physicians and health-care workers. It really is very significant that anybody would be told to "challenge their Doctors"

Effect of Vitamin D Supplementation on Blood Pressure
A Systematic Review and Meta-analysis Incorporating Individual Patient Data

JAMA Intern Med. Published online March 16, 2015. doi:10.1001/jamainternmed.2015.0237

Conclusions and Relevance Vitamin D supplementation is ineffective as an agent for lowering BP and thus should not be used as an antihypertensive agent.

But did the study evaluate whether the kids were "healthy?"  If all they did in the study was measure serum Vitamin D levels and didn't make any comment on whether these kids were ill or continually more sick than their counterparts with "normal" Vitamin D levels, what good is the study?  I would almost bet that there are many school-age children who live closer to the equator who have "normal" Vitamin D levels who aren't as healthy as these children.  My hope is that their government doesn't pull some knee-jerk reaction and pass a bunch of laws meant to "correct a situation" which may not need correcting.

Important ... factors associated with vitamin D deficiency were ... playing outside.

Better not let the kids play outside.

They might end up Vitamin D deficient.

Wait What ?

Interesting blog post discussing the DRI as applied to vit D.

From Debs article on the subject...

http://nutrevolve.blogspot.ca/2015/03/using-dris-vitamin-d-case-study.html

This is the critical error that Heaney and Veugeler make - they measure the amount of vitamin D that would need to be taken in to get everyone in the population up to the RDA blood level - but by definition, that amount is exceedingly high for most.

This tends to be a common mistake, especially coming from a clinicians perspective. If you look at how DRI's are suggested to be used (5), we tell people to plan a healthy diet aiming for the RDA. But when looking at a population and assessing an individual's needs based on some biochemical data (e.g. 25OHD), it's suggested to use the Estimated Average Requirement (EAR) and other clinical markers to determine the possibility of inadequacy. It's critical for practitioner's to understand that we can't just assume everyone in the population needs the RDA, because by definition, it's more than needed by 97.5 percent of the population.

Each of these practitioners proselytizing Vit-D supplementation is themselves taking large quantities of Calciferol.  As time goes by, I would expect the steroid to gradually lose its effect, as do corticosteroids, and those taking it would have to increase their dose.

This is the same cycle (IMHO) which leads to Sarcies getting 120mg of prednisone, and it still not 'doing the job', just prior to them dying of pneumonia, C.difficile (etc).

Regarding to the most recently posted study about menopausal symptoms:

""Our study suggests that women should not rely on vitamin D and calcium supplements to relieve menopausal symptoms, but there are important caveats," said Erin S. LeBlanc, MD, MPH, lead author and investigator with the Kaiser Permanente Center for Health Research in Portland, Oregon. "The average age of the women at the start of our study was 64, but the average age of menopause is 51, and it's around that time that the most severe symptoms usually occur."

Of course there are caveats when you go looking for something and don't find it.

Meanwhile, in Canada:

C-388 — An Act to establish a National Vitamin D Day
    Tabled by: — James Lunney (Conservative, Nanaimo—Alberni)
    Description: “Abundant scientific research in the past decade,” said Lunney, who doesn’t believe in evolution, “has underscored the vital role of vitamin D.” He called for every November 2 to be ‘National Vitamin D Day’.
    Status: Lunney’s bill didn’t see the light of day.

Serum 25-hydroxyvitamin D and self-reported mental health status in adult Dane

Our results suggest that low serum 25(OH)D is not associated with self-reported symptoms/diagnosis of depression and anxiety.

Vitamin D supplements offer limited benefit to obese teens

"For her team's most recent study, they examined the effect of vitamin D supplementation in 19 obese adolescents aged 13-18 with vitamin D deficiency, assessing what influence - if any - it had on their overall health....Dr. Kumar...says that she was surprised not to have uncovered any health benefit."

**Thanks Markt9452 =)
