Death from All-Causes Less Likely with Higher Vitamin D Levels

A new, large-scale observational study by Dai et al., which included data from 37,079 people in the UK with existing cardiovascular disease (CVD), ages 40-69 years, found that death from all causes (including heart disease, and especially cancer) was significantly associated with vitamin D level.

Over the study period, there were a total of 6,319 deaths; 2161 deaths from CVD, 2230 deaths from cancer, 623 deaths from respiratory diseases, and 1305 deaths from other causes.

Those with vitamin D deficiency (levels less than 20 ng/ml or 50 nmol/L) had the greatest potential for reduced risk of death. In fact, for these individuals, every 4 ng/ml (10 nmol/L) increase in vitamin D level was associated with a 12% reduction in risk for all-cause mortality and a 9% reduced risk for CVD mortality.

This means that, for those whose vitamin D level started below 20 ng/ml, increasing their vitamin D level by 20 ng/ml (50 nmol/L) could reduce their risk of death from all causes by 47%, and reduce their risk of death from CVD by 38%.
