As a kind of Vitamin C, ascorbic acid plays a great role in preventing scurvy caused by long voyage travel. For example, in order to prevent scurvy, oranges with rich of vitamin C was provided for sailor and passengers. Although most animals can compound ascorbic acid naturally, but human beings do no have this ability and have to get this nutrition by foods. Cauliflower, spinach and cranberry also have rich ascorbic acid except the fruits like oranges. After getting that ascorbic acid can prevent scurvy, the manufacturers of natural foods start sales of Vitamin C capsules. Besides, vitamin C also is added into many fruit juice drinks.
