Large Genetic Study Proves The Link Between Low Vitamin D Levels And Hypertension

British researchers who analyzed data from 35 studies involving 155,000 people found a strong causal link between low levels of vitamin D and high blood pressure. The researchers said that observational studies had already detected the link, but the large-scale genetic study nailed down the cause and effect relationship. The findings strongly suggest that some cases of cardiovascular disease could be prevented through vitamin D supplements or food fortification, the authors said.
