What are people's favorite probiotic? I could take yogurt, or Kefir, or an over-the-counter pill, or an expensive prescription/mail-order one. Each has its own mix of bacteria. They have done clinical studies on a couple designer bacteria that show they help, but that doesn't mean all the others don't work, right? Maybe it doesn't even matter which "good" bacteria to take, if the point is just to crowd out the bad bacteria.
Anway, which probiotics have people has success with? I am taking Kefir now, but it is pretty expensive, and has dairy and sodium which I might want to avoid right now.
