I wish I could give you a good answer, I too have tried many brands and found most wanting. I was using a product called VSL#3 with great success, but the company had some sort of fallout between the inventor and management and now supposedly what was VSL#3 is sold by another company and called Visbiome. The original company still sells VSL#3 but it is said not to be the same product that worked so well. Sigh
