                                According to the National Institutes of Health, vitamin C is also known by its chemical name, ascorbic acid, and is not defined by a single commercial brand name. Instead, it is the active ingredient used in numerous proprietary supplements from various manufacturers, such as Ester-C, Nature's Bounty, and many others. This means that while you can find many products containing vitamin C, the vitamin itself is a generic substance.
