Summer is here and fun in the sun means your body will produce more Vitamin D. New research says that could be good news for your blood pressure. The study, published in Lancet Diabetes & Endocrinology, showed that low levels of Vitamin D may be a cause of high blood pressure and that for each 10% increase in Vitamin D levels, there was an 8% decrease in the risk of developing high blood pressure.
Vitamin D, or the sunshine vitamin, has long been known to lower blood pressure in animals. The results from studies on humans have been mixed. Vitamin D has not been proven to be an anti-hypertensive, but as this study shows, it can improve blood pressure control.
Bottom Line: Get your Vitamin D levels checked. If you have high blood pressure, correcting the Vitamin D levels should improve blood pressure a bit. If your Vitamin D level is normal, then a multivitamin containing 2000 units per day is a good way to maintain it.
However, if you have kidney disease with an estimated GFR of less than 45, you need to see a kidney specialist to find out the best way to get Vitamin D since the multivitamins that contain combinations of calcium and Vitamin D are not appropriate for those with kidney disease.
