Researchers from the University of Colorado, Boulder recently completed a small study to examine the effect of vitamin C on obesity vascular health. The study examined 35 overweight or obese adults to compare the effects of exercise and vitamin C on a protein called endothelin-1. This protein is known for its ability to constrict small blood vessels.
The findings indicated that a daily supplement of vitamin C via a time-released dose of 500 mg reduced the vessel constriction of endothelin-1 just as much as walking. This study further explores the many benefits of vitamin C, which has also been found to help marathon runners reduce their chances of developing the common cold.
These findings are scheduled to be presented at an upcoming conference with the American Physiological Society.
