If you have Crohn's disease or colitis ulcerosa, DON'T take probiotics. It's been proven to be a bad idea.

Then... don't buy your probiotics just in the store on the corner. It's expensive in all cases, so you'd better buy the good ones. Those in a simple store or not good enough to buy. Only 70% really contain living bacteria, and often not enough. You can say 30% has died already, and of these other 70%, lot's are dying too. The only place you can buy a good product is at your pharmacist.

Probiotics are highly hyped and are expensive. It's nothing more than a commercial product. In fact, most people don't need it. You'd better look for an old farmer, who still makes his yoghurt in a traditional way (very sour result). This yoghurt is much more efficient and healthy then probiotics in most cases.

You don't have to believe me, if you don't want to, of course.
