Research from Wolfson Medical Center in Israel gives a positive report on dietary antioxidants. When used long-term, dietary antioxidants have a positive effect on the metabolism of sugar and fat, blood pressure and flexibility of arteries in people at high risk for cardiovascular problems. The antioxidants used in testing were vitamin C, Vitamin D, coenzyme Q10, and selenium.
Reuven Zimlichman, who worked with the research team, said that supplementation of antioxidants elasticity in arteries and improved glucose and lipid metabolism.
"Previous results from clinical trials into the cardiovascular health effects of antioxidants have been equivocal. In order to shed more light onto the matter, Zimlichman and his colleagues randomised the 70 patients to receive either antioxidants or placebo capsules for six months. Tests at the beginning of the trial, after three months and at the six month mark revealed that the patients in the antioxidant group had more elastic arteries (a measure of increased cardiovascular health) and better blood sugar and cholesterol profiles."
