<<Disclaimer: Verify this information before applying it to your situation.>> Both in Canada and the States I checked with Kraft and they both said their marshmallows are GF. The states was last summer while vacationing I called their 1-800 number and was told they are GF. I also called the 1-800 Kraft Canada number. Sorry do not have them at work but they are on the packages. Also I do not have the names of the people, so write down the 1-800 number next time you are at the store and call them. Very easy and inexpensive. Karen, Edmonton, Alberta, Canada [log in to unmask]
