But runners are different. We are more active than everyday adults. We burn more calories and sweat away more nutrients. We work our muscles and joints harder. That's why Peregrune designs vitamins and supplements for the specific needs of runners. Product Benefits * COMPLETE MULTIVITAMIN FOR RUNNERS: Vitamins A, B, C, D, E plus Zinc.
