One thing I did read through on their site regarding their new 80 Billion Critical Care Bifido Max from Ultimate Flora is they guarantee the bacteria count to time of expiration on the bottle if it's stored under normal conditions. Not sure if that applies to the 50 Billion or not but I'd be curious if your bottle as an expiration date. I've taken the 50 Billion in the past but I'm now on VSL.
