I like General Biotics[1]. It has 115 strains which is an order of magnitude more than any other supplement. One of the founders is a researcher in the field published in all the big name journals. They don't make claims that can't be scientifically supported, unlike most health supplement companies. Highly recommended. 1: http://www.generalbiotics.com/ http://www.generalbiotics.com/
