I am not sure about that Scott. I think that the gel caps release in the small intestine, not necessarily a time release, so should be OK for those without a colon. But, I am sure it is an individual thing.
"To make the pills, researchers processed the feces until it contained only bacteria, and then encapsulated the bacterial concentrate inside three layers of gelatin capsule. This ensured the pills wouldn't leak or disintegrate until they were past the stomach and into the small intestine -- a potential advantage over other methods because it covers more of the GI tract, does not involve invasive and more costly procedures, and is more comfortable for patients, Dr. Louie said."
