PB8 Really works for me
This is the ONLY pro biotic I'll ever use. Works for sour stomach, bloating, nausea. I take 2 every morning on an empty stomach before breakfast to keep from being bloated. Love it!

It works!
I took this in order to avoid a certain female side effect of taking antibiotics. I took two a day during the course of my medication and for several days after completing it. It worked! No unpleasant side effect.

It also worked wonders for my digestive system - no more stomach upset issues!

I plan on continuing to take this daily!

This product healed me
I use the product occasionally now for maintenance of stomach probiotic balance. I strongly recommend this product for anyone whose doctor agrees with use and who have just undergone a round of antibiotics. Probiotics are essential for health in our overmediciated society!

Great Product for a great price!
I have ulcerative colitis and a GNC employee recommended I take these along with some fish oil. They really make a difference. I could tell a difference in less than a week of taking them.

Do I take both pills at the same time or space them out?
A shopper on Oct 26, 2012
