Vitamin C

Vitamin C:
Vitamin C is a water-soluble vitamin found in all fruits with larger amounts in citrus fruits. Unlike most animals, humans cannot synthesize vitamin C in their bodies, and therefore needs to be obtained through food. Vitamin C acts as an antioxidant. It’s necessary for the development, growth and repair of body tissues.

Since Vitamin C is water-soluble, excess amounts of the vitamin will be excreted through urin.

Vitamin C deficiency (scurvy) can lead to symptoms like fatigue, depression and  tissue defects (rashes, petechiae, gingivitis, impaired wound healing and internal bleeding). It has to said that it is uncommon to get a severe deficiency in modern society.
