These definitely are stronger than the 'original formula' one, I'd say taking 2 of these = 3 of the others. Product was delivered really fast, within a week, so I'm very happy with iHerb.com. Dr. Ohhira's seem to be the best probiotics I've taken, as good or better than Primal Defense by Garden of Life. In fact, after having to take a lot of antibiotics over a couple months or so, Ohhira's was what finally got my body back to normal, Primal Defense wasn't sufficient. I took lots of Primal Defense but still felt sluggish, I tried Ohhira's and it finally got my body feeling healthy and not depleted any more. Taking both products at the same time is pretty potent and useful as well, but it was Ohhira's that did the better job when depleted.
