Vitamin C (ascorbic acid ) is one of the very essential water-soluble vitamins.
In many animals vitamin C is synthesised from glucose in their body especially in the liver and the kidneys.
In human beings and other primates vitamin C is not synthesised in the body and it has to be sourced through their food.
Guinea pigs, certain fruit bats and some birds and fish also cannot synthesise this vitamin in their body.
The chemical formula of vitamin C is C6H8O6.
Insufficiency of vitamin C in humans can cause scurvy which can be life-threatening.
Vitamin C is important for the formation of collagen, a form of protein, giving structure to blood vessels, bones, muscles and cartilage.
Collagen is also found in skin, ligaments and scar tissue and is essential in the healing of injuries and scar tissue.

Vitamin C deficiency can cause life-threatening disease Scurvy.

Scurvy is the result of severe vitamin C deficiency. If left untreated scurvy can be life-threatening.
Scurvy leads to spongy and bleeding gums, bleeding mucous membranes, swelling and pain in joints, suppurating wounds, follicular hyperkeratosis and hair loss, dryness of the mouth and the eyes, dry itchy skin and tooth loss.
A person with scurvy suffers from depression and hysteria. However proper diagnosis and treatment with high doses of vitamin C can reverse the symptoms and improve the health.


High doses of vitamin C can result in intestinal disturbances and diarrhoea.


Human body cannot synthesise vitamin C and cannot store it. Hence daily intake is necessary.
Vitamin C is available in fresh leafy vegetables like cabbage and spinach, fresh fruits like mango, guava and papaya, and all citrus fruits.
