Here is a list of sugar free products. Read the disclaimer warning at the top.
You can always ask your pharmacist, too. They can sometimes special order products if they aren't commonly available or stocked in the average pharmacy.
i'm afraid that i can't be of more help, but if you are going to ue a low sugar diet, i don't think it is possible to avoid all sugar, but if there is sugar in a vitamin it would be negligable same as with medications like tylenol. i would also suggest talking it over with a doctor before starting this. Sorry i couldn't be more help. bret
