WATERLOO (KWWL) -

Vitamin D supplements may help African American adults lower their risk for heart disease.

High doses of vitamin D appear to help blood vessels pump blood more efficiently, which leads to a lower risk for heart problems, according to researchers in Georgia.

Experts there enrolled 45 overweight black adults in the study, half received a high dose of vitamin D once a month. All participants underwent scans to measure how well their blood vessels dilated.

Those who had the vitamin D injections saw the health of their blood vessels improve after four months.
