Since the active ingredient here is 5 billion colony forming units of Lactobacillus acidophilus, I wonder how this differs from getting from another source i.e. yoghurt

> Through our research, we discovered a novel strain of lactobacillus acidophilus bacteria that will colonize the mammalian intestine and actively produce an excess volume of lactase enzymes

It would be nice if there was a paper demonstrating the claims about this specific strain of L. acidophilus
