We take a number of different probiotics. Rotating Align and Culturelle in the mornings, and then rotating through AOR probiotic 3, PrescriptAssist, and RenewLife Ultimate Flora, a different one each evening.
The gut contains many thousands of different species, so replacing only one may just not work. Antibiotics and antimicrobial herbs kill pretty widely, so trying to reintroduce a range of bacteria may be more effective.
But again, you need to introduce different probiotics the way you would introduce new antibiotics. One product at a time and slowly to see if you have a negative reaction.
And yes, the doses you mention are low. We regularly take 50 - 75 billion probiotic organisms a day, and more when we add kefir and fermented vegetables.
