Vitamin D deficiency may increase premature death risk

It's often referred to as the “sunshine vitamin”, and now new research shows that vitamin D could prolong your life.


According to a study by researchers from the University of South Australia, there is a causal relationship between vitamin D deficiency and premature death.


For the study, the researchers recruited over 300,000 individuals, aged 37-73, from the UK Biobank. They obtained the participants' genetic data, as well as their vitamin D serum levels.


Over a 14-year follow-up period, the researchers recorded all-cause mortality and deaths caused by cancer, cardiovascular disease respiratory disease. At the end of the research period, there had been 18,700 deaths.


Further analysis revealed that the risk of death decreased significantly with increasing vitamin D levels, but that this effect plateaued when serum levels reached 50 nmol/L.


“In this study, we found evidence for a benefit across all the main causes of death, including cardiovascular disease, cancer, and respiratory disease-related mortality,” said study author Elina Hypponen, PhD, a University of South Australia professor and director of the Australian Centre for Precision Health.


“However, in most cases, any benefit for increasing vitamin D levels was restricted to those individuals who have very low concentrations,” she added.
