Lactose will be listed if added. This isn't likely however as it is a sugar/carb which a low carb product commercial intrest will try to limit so as to attract customers. It is found in milk so any lactose not added might be found in whole/skim milk contents, again not likely to keep carbs down.

Are any of the so called breakfast meal/drinks (i.e. Atkins/Slimfast/Carb Solutions/etc.) good/safe for people who are lactose intolerant?
What specifically do I look for on the contents labels?
