76 year old male. I tried two other probiotic products before Culterelle. Neither helped at all. I did some research on the probiotic issue on medical sites. One source indicated that some can be helped and others can't. This source suggested trying either of two products, Culterelle was one of them. I have been using the Digestive Health version for almost two months now. It has really helped me. It has really helped me become more regular with very little stomach upset. I am pleased with this product but plan on trying the Immunity Support formula some time.
Bottom Line: Yes, I would recommend this to a friend
