Lyophilization is a fancy word for freeze-drying. "If a probiotic is refrigerated, it doesn’t mean it’s a better quality" is of course true. But nothing that I said is false. If I am getting probiotics from a quality source, I am going to prefer the refrigerated product over the "shelf-stable" one every time.

Why do you think they’re here, sharing the info with you?

If you could just Google it up, not nearly as interesting to HN.
