Carol, you might check with Nutri-West. They can answer any questions over the phone, plus they have a catalogue and search function online. They advertise all of their products as hypoallergenic. I checked a couple of them and didn't see any corn fillers listed. I have taken some of their supplements as prescribed by my acupunturist and not had a problem, though I don't have near the allergies that you do. Good luck.
