At the time, we used Natural Factors double-strength Acidophilus + Bifidus. Many are having good success with Renew Life Ultimate Flora, 15bn CFU, but it's expensive. I currently use Nexabiotic because it has the important strains and a yeast-based probiotic called S boulardii, but it's pretty expensive too. I will probably switch to NOW Probiotic-10, the one with 25 bn CFU and separately add the Jarrow S boulardii with MOS.
