Probiotics are in powder form. This is what is in the utility, "live" yogurt: acidophilic, Bulgarian bacillus and others. Stabilized (ie, experiencing good trip, but in the summer I do not advise to book - will deteriorate). very good for the stomach. I can not say for sure about the effect, so I started to take along with a few additions, but I think it's worth it to pay $ 40. Expensive, but if you do not eat every day fresh and acidophilus have problems with the stomach, it is a great option. On the quality did not even say, a manufacturer of more than reliable and does not add to their products are harmful additives (but always check them for, the ideal manufacturer does not happen, except that a couple of good goods sold).
