The following was taken from the Beano website.  I guess I have had no problems with Beano in the past (if anything I usually feel better when I take it), so I probably will continue.

            9. Does Beano contain gluten?

            There is no guideline which defines "gluten-free". The =
smallest amount of gluten that can be chemically detected in a product =
is 0.00016%; therefore, chemical testing cannot establish that a product =
has absolutely no gluten. Results of our testing has shown that Beano =
contains less than 0.00016% gluten. Although the amount of gluten in =
Beano is less than the limit of detection, we would recommend that =
individuals who have concerns about the use of the product speak with =
their physician.
