The Oxygen Advantage: The simple, scientifically proven breathing technique that will revolutionise your health and fitness

Along with beetroot juice, essential nitric oxide-producing, heart-protecting food sources to include in your diet include fish, green vegetables, dark chocolate, red wine (a glass per day – not the bottle!), pomegranate juice, green or black tea and oatmeal porridge.
