Low Vitamin D Linked to Risk of Death
A new study published in Annals of Internal Medicine determined that vitamin D deficiency increases mortality risk. The findings were based on a survey of the vitamin D levels and genetic data of more than 300,000 people aged 37 to 73 that participated in the UK Biobank, a large-scale cohort study that began in 2006. Almost 19,000 deaths from all causes, as well as from specific causes such as cardiovascular disease, cancer and respiratory illnesses, were recorded through 2020.
Researchers discovered that the risk of death decreased steeply with increasing concentrations of vitamin D, until reaching 50 nanomoles per liter (nmol/L). The odds of death from all causes were estimated to increase by 25 percent for participants with vitamin D levels of 25 nmol/L, compared to those with 50 nmol/L.
