Getting enough of the “sunshine vitamin” vitamin D is a must for those with high blood pressure, a new study published in the American Journal of Hypertension recently found. In this study of more than 7,000 adults, a clear link was uncovered between low vitamin D levels in the blood and high systolic blood pressure.
The study authors also discovered how vitamin D affects blood pressure. Vitamin D helps regulate a thyroid-produced hormone known as PTH. When PTH increases, blood pressure does as well. The study found that getting enough vitamin D –either from sunlight, food or supplements—dropped both PTH and blood pressure significantly.
