I looked on their website, but it didn't say anything about it, and I contacted them, but they haven't replied yet.

Hello,

I just called them about the Rapidmelts with Vitamin C and the representative stated that, "no Zicam products contain gluten". I am questionable about the chews however.

So, with that I just took one because my G/F has a cold and wrote it in my journal.

Hope this helps!
