Vitamin C, also named Absorbic Acid. The human body is unable to store Vitamin C and unless replenished constantly, symptoms, the most commonly known of which is scurvy that can become fatal, will quickly occur.
It is important in forming collagen that gives structure to bones, cartilage, muscle and blood vessels and in maintaining bones and teeth, and in the absorption of iron.
Sources are most fruits and vegetables served raw if possible, Vitamin C dissolves in water so if the food must be cooked use the minimal amount of water by steaming or microwaving for as short a time as possible.
Most breakfast cereals and many fruit juices are fortified with Vitamin C. The British are known as ´Limeys´ because the Royal Navy issued limes to sailors to prevent scurvy which could occur due to long periods at sea without fresh fruit and vegetables
