How many cfu should i look for when choosing a probiotic? is 50 billion enough?

Pro mean with: and bio means life. Probiotics help the GI system digest food. Anti means against. So, if one takes excessive antibiotics (which are sometimes needed) they can kill off the good bacteria in our GI systems and we can have digestive problems. LOOK FOR A WIDE VARIETY OF STRAINS RATHER THAN HIGHER NUMBER OF FEWER STRAINS. Peace and good health.

Who knows?: This is a largely unstudied and unregulated area of medicine. Nobody knows for sure whether probiotics help anything. Probably they are not harmful, but it is actually quite difficult to know what bacteria should be included in a probiotic mixture, or how to provide them in a way that they survive in the GI tract. And nobody knows how many CFUs are best; it's mostly guesswork.

These qualities are: The qualities of a good probiotic are the number of good bacteria per capsule and the number of species of good bacteria! 10 billion with ten strains is what to try for! The more the better! So the number is important but the number of good bacterial strains is equally important!
