It is hard just to find a probiotic with Bifidobacterium lactis.
"93% of the probiotics you buy at traditional diet supplements stores will actually be dead before they even reach your digestive system. As you are aware, probiotics that are dead are worthless and will do nothing for your digestive issues and bloating. Unfortunately, many probiotic supplementation products are on the shelf for well over a year, meaning only about 32% of those probiotics survive."
