Vitamin C Works Like Exercise In Obese People

Vitamin C supplements seem to provide the same cardiovascular benefits as regular exercise in overweight and obese adults. The key problem is the increased activity of a small blood vessel-constricting protein called endothelin (ET-1) in overweight people, making them more prone to vascular diseases. Exercise reduces ET-1 activity, but more than half of overweight people never exercise. The U.S. researchers found that taking 500 mg of time-released vitamin C daily reduced ET-1-related vessel constriction as much as walking did.
