My doctor recommended I take a probiotic after a round of antibiotics that is 100 million CFU whereas many yogurts advertise billions of CFU. Why is that the case?
In: Biology
Once you are in the millions of CFU per serving it kind of doesn’t matter. At that point regular consumption and other dietary factors probably have a better influence on if your gut flora changes.
If it’s supplement or food, neither claims about flora concentration are evaluated by FDA. They both contain lots of live culture and it’s doubtful to be anymore accurate than that without far more extensive control.
