Vitamins C and E in smokers/drinkers. Couldn't find this in pubmed yet.
Reuven Zimlichman and other researchers from the Wolfson Medical Centre, Israel, studied 70 patients from the centre's hypertension clinic.
"Antioxidant supplementation significantly increased large and small artery elasticity in patients with multiple cardiovascular risk (smoking and drinking) factors," said Zimlichman.
"It also improved glucose and lipid metabolism and decreased blood pressure," he added. These findings were published in Nutrition and Metabolism.
