Best Probiotic

I'm interested to know what probiotics posters use.

Go in to Holland and Barrett, if your in uk and get acidopullis pills, take 2 a day and keep refrigerated once opened, they are about 12 quid for 100 capsules, I’ve been taking them for nearly 2 months, had some abdominal discomfort for a while took these and pretty much solved my issues.

There must be something to this

My friend linked me some Acidophilus 20 billion from H&B, the name seems to pop up a lot for IBS

I'm on day 2 of taking them. 

Don't suppose you can remember how long it took to notice anything? (I'm a bit skeptical of anything working since everything else I tried for IBS has been no go!) 

Also, didn't know about leaving them in the fridge! 

Would others please give the names of the supplements they use.
