Does the bottle have a nutrition statement? If so, it should tell you if there are carbs. Caramel color is not a food and should have no carbs, the other ingredient I don't know about.

As far as quantity, your body is using the food you eat much more efficiently so that's why there is less coming out the other end. It's perfectly normal.

Personally, I have never taken laxatives, and after a couple months things got quite regular. If you are eating enough vegetables, you shouldn't have any trouble.
