A probiotic is a named strain at a named dose, or it is a smoothie of Latin. Lactobacillus rhamnosus GG, usually written LGG, is the strain with the long file: antibiotic-associated diarrhea, some infectious diarrhea, and a smaller stack of gut studies. Most bottles that say 50 billion CFU and sixteen strains are not that file. They are a census. This page is about one strain.
What LGG has, and what “gut health” does not
The useful trials used around 10 billion CFU a day, often started with the antibiotic or at the first loose stool, and they measured diarrhea, not a feeling of wellness. LGG survives stomach acid better than a lot of grocery strains. It does not move in and colonize you. Stop the capsule and the effect leaves. That is why “take it forever for balance” is marketing. Take it for the job: a course of antibiotics, travel diarrhea risk, or a stretch of bloating you are actually tracking. The microbiome page already prefers food fiber, including psyllium, over a colorful stool test.
More strains is not more evidence. A blend can still help someone. You will not know which organism did it, and neither will the label. CFU should be guaranteed through the expiry date, not “at manufacture,” which is a number from the factory door. Refrigeration is a storage detail, not a sign of seriousness. Some stable strains do not need the fridge. Read that line.
Who skips it
People who are severely immunocompromised, who have a central line, or who are in an ICU do not start a probiotic because a webpage said LGG is studied. Rare bloodstream infections exist in that group. Everyone else: one capsule a day, with or without food, for the stretch you are using it for. On supplementation this stays a maybe with a specific strain, not a membership in gut health.
