Vitamin D deficiency increases the risk of death two- or threefold

Austrian scientists have found a direct relationship between vitamin D deficiency and increased mortality among people aged 45-60 years. It is reported by EurekAlert magazine.

Researchers at the medical University of Vienna analyzed the effect of low levels of vitamin D on mortality in young, middle-aged and elderly people. They used data from 78,581 patients who recorded vitamin levels between 1991 and 2001. Then experts found out which of the subjects died during this period, at what age and from what disease.

Data analysis revealed that low concentrations of vitamin D (about 10 nmol/l) increased the risk of death by two to three times. And the greatest effect was observed among people from 45 to 60 years. 

Increased levels of vitamin D (above 90 nmol/l), on the contrary, reduced the probability of premature death from all causes by 30-40%. And it was most evident in the same age group. Vitamin D deficiency no longer had an effect on mortality in patients 75 years and older.

Notably, vitamin deficiency significantly increased the risk of death from diabetes by 4.4 times. Cardiovascular disease and cancer were also developing faster due to the deficiency of the compound, but the correlation was not so strong.

The researchers also studied the condition of patients whose vitamin D levels exceeded 100 nmol/l. Such a high concentration in the blood did not show any negative impact on health. So, it is impossible to overdo taking this biologically active substance. 

The authors of the study once again demonstrated how important it is for health to take vitamin D, and that it should be done at a young age.
