HealthDay News — Physical activity and vitamin D appear to have synergistic beneficial effects on the risk of atherosclerotic cardiovascular disease, according to a study published in the April 1 issue of the Journal of Clinical Endocrinology & Metabolism.

An analysis of data spanning 20 years from 10,342 U.S. adults free of atherosclerotic cardiovascular disease found that those who got the recommended amounts of exercise and had adequate vitamin D levels had a 23% lower risk of having an adverse cardiovascular event.

People who met physical activity targets but were vitamin D-deficient did not have a lower risk. Though the researchers found that the more people exercised, the higher their vitamin D levels, this was true for whites but not for blacks.
