Vitamin-C and ascorbic acid are the synonyms of each other. If we want to grow, develop and maintain the tissues of our body then, we require Vitamin C or ascorbic acid. If there is a need to repair our tissues and to fight infection then there comes Vitamin-C. It is found in fresh fruits like kiwi, oranges and lemons. Excessive Vitamin C leads to diarrhoea, nausea, vomiting, heartburn, abdominal bloating and cramps, headache, insomnia and kidney stones. The test which is used to determine deficiency and excessive intake of Vitamin C is termed as the Vitamin-C-ascorbic-acid test.
