Healthy kids at play help introduce C-100-C, a new supplement marketed by Novartis Nutrition (Mexico). C-100-C, being targeted to children, combines vitamin C and calcium, and the letter "C" is a recurring image in the 20-second spot; a girl rides a bike with a tire formed by the letter, and a boy bounces a letter "C." Grey Mexico, Mexico City, created the commercial. Topix/Mad Dog, Toronto, handled the animation. Copywriter: Alejandro Sarabia. Art director: Thaina Garza.
