I've taken the CVS brand cheap and the expensive whole foods 50 zillion various brands. I can't tell any difference. My gyne suggested one that she orders online from a lab where it is guaranteed to be alive. So. If I remember I will ask her, again.

Me too,The older I get the longer it takes to think.

I've been on so many, it would take a day or two to figure out which I think is best. Hey, the older I get-the longer it takes me to think. I have "brain farts", which makes it harder to concentrate!

I usually eat yogurt and drink cranberry juice for the UTI.

Probiotics are essential to all, as they put the good bacteria back into your system for your gut, which is where 90% of our immune system is. Gut encompasses digestive track/ stomach. Bad bacteria is there, but overgrows then not enough good bacteria/ essential bacteria is there. Definitely the removal of all bacteria by antibiotics "cures" the initial issue, but then if no probiotics or fermented foods like yogurt to introduce the essential and good bacteria we need for proper functioning, it becones a mess for the overgrowth of yeast, which is kept in check with good bacteria stopping it from continuing to get overgrown. Highly recommend you consult with your physician.
