I got about 9 replies asking about Barium . 3 said it was g f and took
it with no ill affects. 6 thought it was not g f. I called the
manufacturer and they could not guarantee it as to some outside
suppliers. I called my gastro and he said it would be o k to take it. I
am having a CAT scan tomorrow ordered by my urologist. He is not well
versed on what is and what isn't g f. If Ihave any bad reaction I will
post a follow up. Many thanks to the quick responses

I am taking the kind that I have to mix the powder they gave me with a
quart of water and drink 2 hours prior.
