Could Low Vitamin D Lead To High Blood Pressure?
In a study that claims to be the first of its kind, researchers have uncovered “compelling evidence” that low levels of vitamin D lead to high blood pressure.
The researchers for this study used genetic data from the D-CarDia collaboration, which included 146,500 people in Europe and North America. They examined two common genetic variants that influence vitamin D concentrations in the blood.
They found that each 10% increase in vitamin D concentration levels was associated with a 0.29 mmHg drop in diastolic blood pressure and a 0.37 mmHg decrease in systolic blood pressure. Overall, there was an 8.1% decrease in the risk of developing hypertension.
The researchers believe that the Medelian randomization method used in this study helped determine cause and effect. They noted, however, that the possibility of chance could not be ruled out and that further randomized studies need to be conducted in order to determine the exact correlation between vitamin D and high blood pressure.
Researchers from the University of South Australia conducted the study. It was published online ahead of print on June 25, 2014, in The Lancet Diabetes & Endocrinology.
Previous studies have associated vitamin D with reducing the risk of skin damage, reducing the risk of osteoporosis, combating diabetes, and improving age related macular degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
