This site's own ingredients breakdown addresses this directly: the 36mg Probiotic Blend contains three individually named strains, though the split between the three within that 36mg total is not further broken down.
Naming all three strains individually — Bifidobacterium infantis, Clostridium butyricum and Akkermansia muciniphila — rather than a generic "probiotic blend" label is worth crediting, while still noting the internal split isn't disclosed.
Worth reading the 36mg total figure as genuine, if partial, transparency — more specific than an undosed proprietary blend, but not as complete as a per-strain milligram breakdown would be.
