Vitamin C
Vitamin C is a water-soluble vitamin that is found naturally in some foods, that can be added to other meals, and that is also sold as a dietary supplement. Vitamin C is also known by its chemical name, L-ascorbic acid. Because humans are unable to produce vitamin C naturally in their bodies like most other animals are, getting enough of it in one's diet is absolutely necessary [1]. Vitamin C is essential for the production of collagen, L-carnitine, and a number of neurotransmitters. In addition, vitamin C has a role in the breakdown and synthesis of proteins [2].
