This is so weird I had an intuition that I should revisit this site and this is the 1st thing I see on here...
To answer your question I got the "Chewable Acidophilus with Bifidus" tablets from this UK shop called Holland and Barrett.
I'm aware the Holland and Barret brand is only available in the UK but I'm pretty sure the brand itself doesn't matter
Just google "Chewable Acidophilus with Bifidus" and you see quite a few US sites appear (drugstore, vitacost etc)
Hope this helped, btw I'll probably check this site every month/2 weeks so please don't be mad if I respond late (I made a huge thread about my cure thats here somewhere if you wanna read it)
