I'm pretty down on a lot of self-experimentation, but it's worth noting that probiotics are frequently recommended by doctors for many other issues and are unlikely to have harmful effects. I'm not familiar with the strain discussed here, but normal strains are ~$1/day. So the danger is that people might get a bit of false-hope or imagine a connection that's not there. I won't say that's harmless, but it can be a lot worse. I'm more worried that people will latch on to the gut connection and experiment with other "cures". There's an entire world of people poisoning their kids to try and cure "gut problems".
