<<Disclaimer: Verify this information before applying it to your situation.>> My question was whether Herb ox was gluten free or not. Well, I got many responses and some said it was and others said no. Then a few said just the cubes. Not being satisfied with this, I personally called their customer service this morning and I was told that "VERY DEFINITELY" all their bouillon, whether it be the cubes or packets, or regular or low sodium, are ALL GF. I was concerned about the "disodium guanylate" and was told it was GF. The front of the box, in bold capitals, say that there is no MSG added.\\ I did try a packet and had no problem. Usually, after drinking a cup of broth, if I'm going to have a problem, it's 30-60 minutes after ingesting it. I had no problem with Herb ox. Simone, NH
