Last I checked, the literature was somewhat equivocal about the benefits of "probiotics in a pill" anyway, compared to something like a tablespoon of fresh lactofermented sauerkraut twice a day. That conclusion matches my personal experience too.

The literature is actually quite robust on the benefits of probiotics. Take a look at the different peer-reviewed studies just on this list of products sold in the U.S. [1]. The quality of these studies is quite high, and highly scrutinized.
