Excess levels of Vitamin D linked to higher death rates

That's me stuffed then. I just started supplementing with 5000 IU a day (the recommended dose on the packet is 10,000 IU a week). I must admit, I've been feeling extra-wonderful since I started doing it.

Now it seems that I've increased my chance of dying by 40% (which I thought was more or less 100% anyway, in the end).

Of course it's down to that headline grabbing "relative risk" thing again. 40% increase on an incredibly small risk, is still an incredibly small risk.

(Being the Daily Mail, I'm surprised they didn't make the connection between hot-places, VitD and asylum seekers).
 
Stephen if you read the article the study was done in Denmark where they have more sunshine and eat more oily fish, so this report doesn't really apply to us. I take between 4000 and 6000iu as a supplement each day. I ain't dead yet. :lol:



Data from the UK’s national nutrition survey showed no Britons had levels of vitamin D as high as those found at the top end in the study, which may have been affected by the fish-rich diet enjoyed by many Danish people, she said.

‘The Danes actually get a lot more sun exposure than Britons and eat a lot of oily fish. Although this is healthy in moderation, oily fish also contains high levels of vitamin A which can be harmful and toxins which may have had an effect on people’s health.

‘One-quarter of Britons go into the summer with levels of vitamin D below the level for optimal health, we have the problem of too many people consuming too little of the vitamin’ she added.

In the UK, the Food Standards Agency does not recommend a specific daily dose of vitamin D unless you are elderly, pregnant, Asian, get little sun exposure and eat no meat or oily fish when 10mcg is advised.

This is from (the slightly Used-Car-Salesman-Like) Dr. Mercola "Based on the latest research, adults need to take about 8,000 IU’s of vitamin D3 per day to reach levels of 40 ng/ml." I assume he means adults with a deficiency...

Those pesky Danes though are using nanomol (nmol) of vitamin per litre of blood serum.

To convert from one to the other the Internets tell me to divide the nmol figure by 2.496 to get the ng/ml (http://www.globalrph.com/conv_si.htm)

Sooooo, the dangerous level for Vitamin D is 56 ng/ml according to them?? Eh?

According to Mercola "it’s important to regularly measure your vitamin D levels to make sure you’re maintaining therapeutic levels of 50-70 ng/ml year-round."

Something weird going on here, possibly just a massive maths failing from me...

It will apply to those who supplement their diet and exposure to sunlight with Vit D.....like ourselves!

Researcher Darshana Durup, of the university’s faculty of health and medical sciences, said ‘We found higher mortality in people with a low level of vitamin D in their blood, but to our surprise, we also found it in people with a high level of vitamin D.
‘We can draw a graph showing that perhaps it is harmful with too little and too much vitamin D.
‘It is important to conduct further studies in order to understand the relationship. A lot of research has been conducted on the risk of vitamin D deficiency.

'However, there is no scientific evidence for a "more is better" argument for vitamin D, and our study does not support the argument either.
‘We have moved into a controversial area that stirs up strong feelings just like debates on global warming and research on nutrition. But our results are based on a quarter of a million blood tests and provide an interesting starting point for further research.’

She said ‘Our data material covers a wide age range. The people who participated had approached their own general practitioners for a variety of reasons and had had the vitamin D level in their bloodstream measured in that context.

'This means that while the study can show a possible association between mortality and a high level of vitamin D, we cannot as yet explain the higher risk.’



Certainly from my own point of view I'll be taking precautionary action and asking for my levels to be checked......just to be on the safe side :wink:

The Danish Health and Medicines Authority recommend a daily intake of 7.5 µg of vitamin D. Most Danes get 2-4 µg of vitamin D from diet. As in the UK the sun is too low in the sky to cause vit D production in winter. They get a bit more sun in the summer, 100 hours between April and the end of Sept.
7.5µg =300iu

(there's a copy of the graph at the link)
But, as they say it's a starting point to research, there may be other explanations for the higher number of deaths.

Having been diagnosed with Vitamin D deficiency, I supplement with 4800 IU of Vitamin D a day (800 IU in Calcichew D3 Forte on prescription and 4000 IU in Dlux spray), I also take magnesium. I would rather do this than suffer with the extreme tiredness and depression I had with the deficiency. I don't get out in the sunshine much or eat many foods rich in Vitamin D. I don't have calcium deposits around my heart. So I'm not worried about this report.
 
Found this article rather alarming

Did you miss these other Daily Fail headlines :

Crossing the road linked to higher rate of being run over by a bus.

Driving a car linked to greater risk of death.

Getting up in morning more dangerous than staying in bed, study suggests.

Eating poses greater risk of death by choking.


I'm going to lie down in a dark room. Wonder what that's linked to (other than not getting the vitamin D I need.)

promoting fewer lies, **** lies, and statistics.
 
well actually more people die in bed, so beds are dangerous things... :)
 
From the same study :

Similarly, both high and low levels of albumin-adjusted serum calcium and serum PTH were associated with an increased mortality[/quote
http://jcem.endojournals.org/content/ea ... 6.abstract

Somehow this didn't get mentioned.
Is it less attention-grabbing ?

Been looking for figures with little success. Only that 6.1% of the study participants died within an average of three years.
I'd love to see more details of those deaths than the vit D level.
Copenhagen University's website offers little.
