That’s why Visbiome ships in insulated packaging with ice packs. There’s even a color indicator that turns red if the contents exceed a temperature during shipping (and refunds are granted if this indicator is red when it receive the product). You then store in the freezer. Unfortunately, the product does not contain L. Reuteri.
Yes I use it regularly. But I don’t have IBS, Crohns, or any other GI disorder. I use it to periodically populate my gut. So to answer “am I satisfied” is difficult. I don’t notice a difference with or without it, because none of us are consciously aware of our gut micro biome. I could say “well I haven’t been sick in years”, but who knows what else contributes to that.
