Product Selection in the United States

There are many probiotic products on the market in the United States, but only four commercially available agents have been tested in placebo-controlled, double-blind studies: L. rhamnosus GG (Culturelle, CAG Functional Foods), S. boulardii (Florastor, Biocodex Inc.), L. acidophilus-L. bulgaricus (Lactinex, BD), and L. reuteri (Primadophilus, Nature's Way, and Probiotica, McNeil Consumer Healthcare). This is not to say that other probiotic products might not be effective; there are simply no well-controlled studies. Only those probiotics shown to be efficacious and safe in controlled studies can be recommended.
