Antioxidants work by minimising the formation of these free radicals. By actively ridding the body of free radicals, Vitamin C helps the horse recover more effectively from illnesses, injuries and viral situations.  Vitamin C aids general metabolism and in the formation of red blood cells, it also has a role in maintaining healthy cartilage, blood vessels,  tendons and bones in the horse.
