High-dose probiotics are best reserved for individuals under severe chronic stress, recovering from antibiotics, jet-lagged, traveling excessively, working excessively, lacking sleep, or experiencing radical dietary changes.

“That does not mean that ingesting probiotics in any form or any kind is not good. It just means that the very high dose probiotics, again, typically found in prescription form or capsule pill form probably are best reserved to cases where of course your doctor prescribes them. You should always follow your doctor's advice. But in cases where perhaps you are jetlagged, you're traveling excessively for any reason, or working excessively, you're not getting enough sleep, or your diet is radically changed from normal.”
