Answer: Yes

According to the Wrigley website React 5 Gum contains the following:

INGREDIENTS:MADE OF: SORBITOL, GUM BASE, GLYCEROL, MANNITOL, NATURAL AND ARTIFICIAL FLAVORS, LESS THAN 2% OF HYDROGENATED STARCH HYDROLYSATE, ASPARTAME, ACESULFAME K, SOY LECITHIN, BHT (TO MAINTAIN FRESHNESS), COLORS (BLUE 1 LAKE, BLUE 1, RED 40). PHENYLKETONURICS: CONTAINS PHENYLALANINE.

But Gum Chewers beware and read your labels….some gums do contain gelatin. I believe Ice Breakers Cubes is one of them.
