<<Disclaimer: Verify this information before applying it to your situation.>> Question: Is Pepsid AC GF? Responses: Four very kind people responded that the mfr., Merck Johnson & Johnson, would not guarantee it is gf. I followed up with the consumer info number 1-800-755-4008, inquiring specifically about the CAPLETS. (Note, the tablets contain "starch." The caplets contain "corn starch.") The person at Merck told me they do not add any gluten to the caplets, but can not be sure what their suppliers do. We have all heard that before, haven't we. The ingredients in the caplets are: benzyl alcohol, black iron oxide, butylparaben, castor oil, edetate calcium disodium, FD&C Red #40, gelatin, hydroxypropyl methylcellulose, magnesium stearate, methylparabel, microcrystaline cellulose, pregelatinized corn starch, propylene glycol, propylparaben, sodium lauryl sulfate, sodium proprionate, talc, titanium dioxide. Because the caplets are very small, because the ingredients look ok, and because we'll only be taking them for three months and will be having a biopsy immediately end of that three month period (for another condition, but it will tell us if there has been villi damage), we're going to go ahead and take them, but that's only a personal decision and I'm not advising anyone else to do it. Again, please note the inert ingredients in the caplets are not the same as the inert ingredients in the tablets. Andy Thomson Chicago
