Vitamin d supplements may help lower blood pressure in African Americans.
High b-p is much more common in African Americans than in other populations, and is linked to heart attacks, heart failure and stroke.
Researchers at Brigham and women's hospital in Boston divided 250 African American adults into four groups of varying levels of vitamin d supplementation. Those who took higher levels of the vitamin had modest declines in their systolic blood pressure readings.
That's the number on top, which measures the pressure in the arteries when the heart beats.
