CARRIE, I don't personally eat it so can't totally comment on those brand names, I use JOK N AL raspberry or strawberry, or at least I did, no one is carrying it any more so I will have to look for an alternative soon.
As long as they fall under the 3 gram rule and are not sweetened with any sugar or it's derivities, they should be okay.
Please come to our SUGAR BUSTERS SUPPORT BOARDS
where you can post your question to the gals there-I'm sure they'll give you some good feedback on what they are using.
