Vitamin C belongs to the class of water soluble vitamin. Basically there are two classes of vitamins namely water soluble and fat soluble vitamins.Both these class of vitamins as well as many other nutrients are required by the body in sufficient amounts to perform all its, functions at optimum levels.
Lack of vitamins in the body usually leads to minor symptoms. But lack of some important vitamins like vitamin C can lead to diseases in the body as well. Being a water soluble vitamin, there is no risk of excess accumulation of vitamin C in the body. Water soluble vitamins if present in excess in the body are excreted through urine. So excess of vitamin C does not produce any symptoms or diseases.
Vitamin C helps in formation of collagen. Collagen is a type of protein. It is required by the body to form supporting matrix that supports the blood vessels, connective tissues and even bones and cartilages.
Collagen forms about 25% of total proteins in the body. If there is deficiency of vitamin C in body, collagen formation fails and it further leads to bleeding due to rupture of blood vessels and capillaries. In severe cases, there is fracture of bones on small impact.
Vitamin C also helps in absorption of iron from vegetable foods that we consume. It helps to convert iron in ferric form to ferrous form. Without the availability of sufficient vitamin C in body, iron absorption also decreases and, this can lead to iron deficiency; which causes further trouble.
An important disease due to vitamin C deficiency in body is scurvy. In scurvy, there is bleeding from gums. Gums swell and that makes them look unhealthy.
Bleeding can even occur in the skin and joints. Small capillaries under the skin burst and cause bleeding in the skin. These can be seen as dark reddish to brown patches over the skin like the appearance of a bruise.
Bleeding in the joints is also called as haemarthrosis. There is delay in wound healing, anaemia due to blood loss and weakness. All these symptoms will disappear if you consume vitamin C in sufficient amounts daily. 40 to 60 mg is the recommended daily allowance of vitamin C.
