My understanding is that this contains only 3 strains of Lactic Bacteria and uncertain if they are SBO's. Not suitable for everyone. Furthermore it is "freeze-dried" where revival rate of bacteria is very low.
You need to consider a "live" probiotic that delivers the bacteria alive to the GI tract and which gets to work immediately. Should have as many strains as possible and more importantly "colonizing" bacteria. Only those bacteria suitable to the human GI tract can be colonizing, ie., they are permanent because they can attach themselves to the intestinal walls to prevent re-infection.
