Akkermansia abundance

Reliability: moderate

Relative proportion of Akkermansia muciniphila among bacteria detected in a stool sample, not a standalone metabolic health score.

If your result is high

Higher relative abundance associates with leaner metabolic profiles in some cohorts; may increase with certain fibers and polyphenols in intervention studies.

If your result is low

Lower abundance reported in obesity and T2D cohorts; may be below detection on shallow 16S panels.

Notes
Species-level detail on Akkermansia muciniphila. Cross-feeding with butyrate producers, see multi-marker synthesis.

Reports that highlight Akkermansia muciniphila (or “Akkermansia %”) show relative abundance in a stool snapshot, not colonization density in mucus, not a validated metabolic health score, and not interchangeable with pasteurized A. muciniphila supplement trials.
