I,ve did some research On BB-12 and Bb-12 is just a trademark that some companies use to individualize their products. it also goes by other names Such as Bifidobacterium lactis Or bifidiobacterium animilias I belive it worked for beastgun because It isn't found in many probiotics but im currently taking a probiotic with B.lactis and also im on a vegetarian diet and I belive my odor is significantly reduced.
