<<Disclaimer: Verify this information before applying it to your situation.>> I just spoke with Denise Sertori at EZ EM the manufacturer of Readi-Cat and Ready-Cat 2 barium sulfate contrast media which have been named as not GF in prior messages to this list. The Readi-cat products have all GF ingredients and she will fax that info if needed. She is going to call me back about the Readi-cat 2 product line as it has one sweetener not certified yet by the supplier. Other potential troublesome ingredients for some of us include gums, Readi-Cat uses Xanthan not guar gum. (good for me anyway). no soy, no lactose, gallactose, mannitol, does have sorbitol. No canola, apple pear or pectin. Does have pottasium sorbate, orange flavor both natural and artificial, artificial vanilla, and sacharin. She read me the entire list of ingredients after I asked about so many ingredients. They can be reached at 1-800-544-4624 8AM to 5PM Eastern US time. Hope this helps, Mike in wichita, ks USA
