55+ probiotics

These are the best I have tried and I have tried a few. I could tell the difference with my bowels when I started to use them and not with the others I tried. I will stick with these.

Best yet

I have tried many varieties over the last years. This is the best one for me. Don’t know why? Could be because I am well over 50, and they have chosen the right strains, such as more bifida. Or the fact that it is slow release.
