Bifidobacterium bifidum is a bacterium that shows up, with no strain code attached, in nine products we track — more than almost any other Bifidobacterium species on this site. That popularity on labels doesn't come with research behind it: we found no dog or other-species study testing B. bifidum specifically. No studied dose exists either, so there's nothing to check CFU claims against.
PubMed and PMC, dogs only. Other species are listed separately below and don't count toward the badge.
We don't have a confirmed CFU-per-kg dose number for Bifidobacterium bifidum from the canine trials yet -- so this calculator is intentionally disabled rather than guessing.
Not based on what we found. Despite appearing on nine products we track, no canine or other-species study of B. bifidum turned up in our research.
No. NCIMB 30179 is a specific identified strain; a label that just says "Bifidobacterium bifidum" with no code is a broader, weaker claim.
None confirmed — no studied dose exists in the research we reviewed.
