Injections of vitamin C given to smokers reverse one of the most harmful cardiovascular effects of smoking, according to a study being published today.
However, more research is needed to determine whether vitamin C pills might help reduce heart disease associated with cigarettes, said the authors of the study, published in the American Heart Association journal Circulation.
The vitamin works because of its antioxidant function, said Dr. Thomas Munzel of the University of Freiburg in Germany, one of the study’s authors.
Cigarette smoke contains powerful oxidants - chemicals that react like oxygen, which rusts iron and makes peeled apples turn brown. High concentrations of vitamin C or vitamin E neutralize oxidants.
