"Vitamins A, C and E are essential nutrients which have antioxidant activity."
"Vitamins A and E are fat-soluble vitamins, meaning they’re stored in your body’s fat cells, but they need to have their levels topped up regularly. Vitamin C is a water-soluble vitamin. Your body stores all water-soluble vitamins except for vitamin B12 for only a brief period of several weeks to several months and then gets rid of them through the urine."
"Vitamins A, C and E have antioxidant properties. This means they can override harmful molecules, known as free radicals, which are produced within your cells and which may cause tissue damage or disease. Your body produces its own antioxidants but it’s thought that antioxidants in the diet (such as vitamin C) help destroy excess free radicals."
