Several companies package chewable vitamin-C tablets in Life Savers-like rolls, but White-Williams Vitamins Inc. is building its whole business around the concept. The Boulder, Colo., company has begun marketing rolls of chewable B-complex and a kids' multivitamin, along with rolls of chewable C. The packaging puts the product up by the candy at the cash register -- the ideal spot for impulse buying.
