Not particularly.
The few batches we've bought have been legit (Ranimax 150, product of India), but QA with these sorts of vendors isn't exactly guaranteed (for all I know, your first purchase would be reconstituted sawdust and rat droppings). I'm not comfortable giving standing referrals to any fly-by-night operation.
I just mentioned it as a possibility because for those with bad-enough GERD, there are no retail options, and the assumption is that the product has been recalled worldwide. Not so!
