This vitamin plays an essential role in vision, particularly night vision, normal bone and tooth development, reproduction, and the health of skin and mucous membranes (the mucus-secreting layer that lines body regions such as the respiratory tract).
For example, a number of the B vitamins are important for making red blood cells, and metabolism of a variety of compounds during digestion. Others have uses in more specific parts of the body; for example, vitamin A is important for our eyesight, whilst vitamin K plays a major role in the clotting of blood. Similarly, deficiencies of vitamins can also have effects; a lack of vitamin C can lead to scurvy, the bane of sailors before the role of vitamin C was understood. A lack of vitamin K can cause bleeding problems, which is why newborn babies are given a shot containing the vitamin, preventing bleeding on the brain and the subsequent potential brain damage.
