Vitamin C
 

Also known as L-ascorbic acid, Vitamin C is a water-soluble vitamin that is naturally present in some foods, fortified in others, and available in many dietary supplements. It is a necessary dietary component because unlike Vitamin D, endogenously (that is, inside the body) we have to get it from an outside source like an orange. Vitamin C is a large component in the building of Collagen, which is essentially the microscopic stuff that hold our skin and ligaments tight and flexible, as well as the nutrient that heals our wounds. A person who wishes to remain active and healthy must maintain good Vitamin C levels. It is one of the few compounds we can take into our bodies at almost any dosage. The body tends to only absorb what it needs and expels the rest through urination.
