<<Disclaimer: Verify this information before applying it to your situation.>> Hi Listmates! I am having no luck finding out the status of Lactulose by PMS as to whether it is glutten'gliadin safe! No ingredients listed on bottle at pharmacy , no info in book , the company is not listed under glutten-free co. the pharmacyist is trying to get answers from the company but so far nothing, I have searched the net lot's of info but not regarding Glutten .. Metamucil did not work for my daughter need to try this but can not til I know it is GF she is having enough trouble I certainly do not want to harm her villi! Man oh man ya go to the Dr's they tell ya to try this and this and that... then you spend days trying to make sure you can safely give it ! Grrrr! Debi, thinking ALL ingredients should be labelled on EVERYTHING!!!!!!
