The men who have a sufficient contribution in vitamin D would run half less risk to undergo a fatal heart attack or no, compared to those that present a deficiency, return an American survey of the Harvard1 university.
These results, gotten by 1 350 men followed during ten years, militate in favor of a revision to the rise of the daily contribution in vitamin D advisable in the Nordic countries.
Among the participants, 454 men underwent a heart attack, 102 of which were deadly. These men were more numerous to smoke, to be sedentary and to make the plumpness.
However, after having isolated these factors of risk, he / it seems that the effect of a deficiency in vitamin D should also be taken in consideration. The participants who had an insufficient blood rate in vitamin D (15 nanograms by milliliter or less) were 2.4 times more to risk to undergo a coronary thrombosis – fatal or no. that those of which the rate of blood was sufficient vitamin D (30 ng / ml).
Every increase of 1 ng / ml of vitamin D in blood in general resulted in a reduction of 2.1% of the risk of heart attack, and of 4.3% of the fatal heart attack risk, in particular, the researchers also observed.

In this survey, only a man out of four (23%) displayed a blood rate judged sufficient in vitamin D, what is representative of the situation of the Nordic countries, the researchers estimate.
According to them, these data should incite the organisms of public health to make higher contributions the daily recommended in D. vitamin
According to the main author, Edward Giovannucci, the studies counted on the topic indicate that a supplement of vitamin D is safe until 10 000 IU per day.

On his / her / its side, the Canadian Society of the cancer recommends to all adults to take at least 1 000 IU per day, during the fall and the hiver2.
"These recommendations are too curators, indicate Edward Giovannucci. He / it is of as much more important to increase this contribution that the periods of sunshine are even less under our long-Nordic latitudes that to the south." He / it suggests for his / its part a dose of 3 000 IU per day.
