Ascorbic acid (vitamin C) is an essential vitamin that is well known for its effects on the immune system. Ascorbic acid is
naturally sour and is commonly used in candy to add a sour taste. When it is ingested, it goes to work circulating through all of
the watery areas of the human body (once it has been absorbed into the intestines, of course). From there, ascorbic acid may help
in the fortification of collagen while acting as an antioxidant during the trip. It may also assist in the repair of damaged
tissue and in helping to maintain healthy levels of collagen in already healthy individuals. Vitamin C also has a host of other
general uses.
