Hi Baba222

Here's a link to Labdoor (independent lab testing) results for probiotics.

I recently purchased two different brands from iherb: Lactobif by California Gold Nutrition - (sample pack) and Nutrition Now PB8. (if you want to see specific probiotic types and ingredients search iherb and zoom in on the product labels).

So far I've only tried the Lactobif and what I've been doing is opening a capsule and adding it to the mix when I make up home-made yoghurt. (ie: 1 capsule per 1 litre) The probiotics multiply naturally in the yoghurt. I've noticed that my stomach has been more settled since starting this (better than with just the plain acidophilus yoghurt).

Sometimes if you're not used to taking probiotics they can cause stomach problems as your gut flora adjusts. Try taking 1 every few days at first then increase to daily over a few weeks if you have problems. All the best with finding a probiotic that suits you.
