"We studied the 247,574 Danes vitamin D levels in the blood, which constitutes by far the world's largest data base on such research in the sample of subjects after the first blood samples, we analyzed 70 years Danes mortality within these, in the meantime there are 16,645 deaths. in addition, we also investigated the death and their blood levels of vitamin D contained in the correlation between. "Linchuan Medical School Peter Shi Professor Edwards (Peter Schwarz) explains.

Conclusion is obvious: study confirmed the association between mortality and low levels of vitamin D, but a new discovery is the higher vitamin D levels also risk factors.

"We investigated the patient's death, when the blood vitamin D levels above 100 nanomoles, they died of a stroke or a higher risk of coronary heart disease. In other words, blood vitamin content should not be too high or too low D it should be between 50-100 nmol per liter between, our research shows that 70 nanomolar level should be the most appropriate. "Schwartz states that.

Never Studies have shown high levels of blood vitamin D are also harmful to health, it may affect our future intake or nutrient supplements before that.
