I remembered some one saying their Crystal Light was made w/ sucralose, so I lwas looking at the ingredients on the back of the new one my wife just got at the store, and citric acid is #1, and maltodex is #2! It still says zero carbs, and zero suger on Nutrition Information label. How is this possible? This one is the pink lemonade, and I then looked at a raspberry iced tea one, and the #2 ingredient is "corn sugar solids**". I looked at the asterisks, and it said "trivial amount of sugar". I've heard that they're not sure how aspartame affects blood sugar, so I've watched my intake of CL while dieting, but now I'm even more suspicious......
Looks to me like whatever the case, you definetly have to watch the amounts you drink.
