Thanks for posting this, it will be very useful.
In regards to packing probiotics in ice/keeping them cold are their shops that actually do this in the US? In England I have never seen this, the major health food store Holland and Baretts always puts them on the shelf. Also the only Whole Foods store in the UK also puts them on the shelf.
Does this make the products useless or does it only matter once you have opened the bottle?
If so I have no idea where I would buy them from if iherb don’t package them suitably.
