Hi doctors, is it correct that consuming probiotics makes our body not to produce good bacteria? thanks.

Not correct: Probiotics do just the opposite, they colonize your body with good bacteria. More recent information suggests connections between the gut flora and a number of illnesses.

Not even close: making the laughable assumptions that probiotics have living bacteria in them, that they somehow get through the stomach acid into the colon. 1) the body doesn't make bacteria. Bacteria sit on the outside.. on skin, in colon, any place they can get to. 2) probiotics are by definition good bacteria. If it's bad bacteria then it's called "food poisoning".
