Very Good Product Have Taken For long Time Works Well Easy Swallow amd Well Priced
Have purchased this 6 times, (Note: I know there is a 150 count size but it's same price per pill, so no savings and 150 count is a tall bottle - does really fit in my plastic vitamin box for all supplements and Rx when I tried it I.E. 100 just more convenient size for me. Several years ago Doc advised a probiotic - ordered this one and showed it to him - said it was fine, but a lot of good ones and 21st Century Brand is as good as many. This has worked well for me and price has stayed very reasonable. I agree with comments that it's an easy to take capsule - personally any vitamin/supplement I look for on Amazon has a first criteria of being a capsule. Found some of these tablets (not coated) esp Vit C kind of start to disintegrate a bit after awhile. Anyway, agree with Amazon summary of reviews - good product, well priced and works well.

Works for constipation and spicy food.
I used to struggle with constipation and got diarrhea every time I ate spicy food. But this supplement has made a huge difference! I take it with water first thing in the morning on an empty stomach. Within about three hours, I have a bowel movement, and it's a healthy one. When I eat spicy food, I take it along with my meal, and it prevents the diarrhea. This is the best probiotic I've ever tried. It's truly amazing.

Great Product and Great Price
This is a great probiotic. I have been using this product for many years at my doctor's advice. This stuff really works for good gut health. Easy-to-swallow pills just once a day does the trick.
