<<Disclaimer: Verify this information before applying it to your situation.>> Hi Geri, I bought some vitamins last summer, because the sales clerk called the mfg. and confirmed them to be g-f, in my presence. I had a reaction the first day I took them, so I phoned the mfg. myself. The said they had oat straw in them, but there was no gluten. I had made a point to have nothing else that was new in my diet that day, as I was still a little dubious. Now we are told that oats may be okay, so I don't know what to think. I only know that they made me sick. Hope this is helpful. Ron Hoggan Calgary, ab, Canada
