Sixteen bacterial species across roughly 3.3 billion CFU, with most strains contributing about 180 million CFU each. While the species diversity looks broad on the label, the total count falls toward the lower end of the 1–100 billion CFU range used in clinical research — many studied protocols use 10 billion or more for meaningful gut outcomes.
The bigger issue for you is that none of the 16 species list specific strain identifiers. Probiotic research is strain-specific — *L. rhamnosus GG* has very different evidence than generic *L. rhamnosus*. Without strain IDs, there's no way to connect what's in your capsule to what's been tested in trials.
**FOS** is included as a prebiotic at 50 mg, but clinical studies on prebiotic fiber use 5,000–10,000 mg. At this amount, the prebiotic contribution to your gut bacteria is negligible.
Every active here is dosed below the amount studied to work. See how each one compares in the breakdown below.
