Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin and very potent antioxidant that is found in citrus and other fruits and vegetables. This vitamin enhances your immune system and is critical to the formation of collagen, which is important for the growth and repair of body tissue cells, gums, blood vessels, bones and teeth.
Vitamin C also protects against the harmful effects of pollution, infection, and even many forms of cancer by counteracting the formation of nitrosamines.
