Vitamin C is the best known vitamin. It is, among other things, needed for the development of connective tissue, the uptake of iron and the maintainance of the immune system. Vitamin C is an antioxidant: it protects the cells in the body from free radicals. Free radicals play a role in aging processes.
Source
Almost all animal species are able to produce their own vitamin C. However, humans are not. They are fully dependent on food for their vitamin C supply. The main sources of vitamin C are vegetables, fruits and potatoes. High in vitamin C are citrus fruits, kiwis, berries, strawberries and cabbages.

Shortage
A prolonged serious shortage may lead to decreased immune system, delayed wound healing and eventually scurvy. The symptoms are bleeding gums, subcutaneous and internal bleeding.
Overdose
Too much vitamin C can be harmful, although the surplus is peed out. An excessive intake can cause intestinal problems or diarrhea and increased discharge of oxalic acid in the urine.
