The CFU metric for probiotics is less relevant than the functional activity of the microbes and only accounts for viable organisms.

“and I have you know 10 times more Colony forming units than somebody else you know again that's maybe that's interesting but it's less relevant than than the function of what's happening in your pill — and moreover it only gives you a uh one piece of data about what's in that pill so when you do that the only thing you get to see are what's able to form a colony but actually in almost every supplement every probiotic out there the majority of what's in that pill is dead probiotic and you don't see any of that when you use this technology”
