The latest on vitamin D status and mortality

Posted on: January 3, 2013   by  John Cannell, MD


Dr. Tea Skaaby and colleagues of the Research Centre for Prevention and Health at Glostrup Hospital in Denmark, just published the latest study looking at vitamin D levels and death rates. This was the first study that investigated the association of vitamin D status and different specific causes of death in the same study population.

    “the highest quartile had a mean of 32 ng/ml”

    – isn’t even 32 ng/ml too low to have any significant influence on cancer or cardiovascular disease?

  2. Rita and Misty

    Heaney argues that 50 ng/ml (125 nmol/L) should be the minimum.

    I’m sticking with 65 ng/ml as the goal for now. It seems to be the “mean of the mean” of recommendations. Anyone think that might be dangerous?

  4. Rita and Misty

    I keep mine higher…85 ng/ml is my target. Just took a test last week…looking forward to learning the results. πŸ™‚

    Mike, not sure if that was a rhetorical question, but 65 ng/ml is indeed in the middle of the normal range set by the Endocrine Society (30-100 ng/ml). So you are quite in the middle.

    theguru, research is underway to find out if 32 ng/ml is too low for effects on cancer and cardiovascular disease. Hunter-gatherers that get year-round sun exposure have higher levels (around 50 ng/ml), so there is some thought that 32 ng/ml is low. Randomized controlled trials are underway to find out; they will be complete in 5-7 years.

    I am a 75 year old Norwegian citicen, with a 6 year old untreated prostate cancer diagnosis. I have supplemented my D3 intake with 10- to 15,000 iU vitamin D3 daily the last 4 years and my level have increased from 40 to 78 ng/ml. I have added 150 mcg K2 daily during these years. Will it be necessary for me to increase the Vitamin K2 intake in light of the danish results showing arterial calcification without sufficient Vitamin K2 when having a high Vitamin D3 intake?

    Now would be a good time to find out how much vitamin D will prevent the complications of the flu. The big news on TV today is that this is the biggest flu epidemic in a long time. What would be interesting is the serum vitamin D level of people that get the flu. My goal over the last 6 years or so is to keep my vitamin D above 100. It seems to me the Danish study has vitamin levels so low the study is useless and stupid. It’s like tyring to deremine if eating two eggs a years raises cholester

    ol levels more the one egg a year.

    @Henry….we are on the same wave length. My 25(OH)D level as of January 1, 2013 is 104 ng/ml. This is after supplementing with 32,000 iu of D3 since October 1, 2012….During the summer, my level was around 75 ng/ml, with 16,000 iu of D3 daily and approx 2.5 hours of high sun per week (I live in CT).

    I originally thought it best to maintain a level of 85 ng/ml….now, I am wondering if this level is too low to stave off the flu.

  9. Rita and Misty

    I just reread my above post, and realized I left out an important tidbit of info… For those who are wondering… YES…I was taking 32,000 i.u. DAILY from 10.1.12–01.01.13. πŸ™‚

    @HENRY, a study assessing vitamin D status of those infected with the flu, as well as those exposed, but not infected would indeed be intriguing. Did you see Dr Cannell’s recent blog post discussing the early flu season? If not, take a look: http://blog.vitamindcouncil.org/2013/01/09/dear-dr-cannell-flu-season-hits-early/
