In certain medical conditions, probiotic supplements may actually make things worse. If you’ve ever made sauerkraut at home, you know you don’t have to add any kind of starter bacteria to get it to ferment, because the lactic acid-producing bacteria are already present on the cabbage leaves themselves out in the field.
