Overview
Adlercreutzia is a genus of Gram-positive, strictly anaerobic gut bacteria within the phylum Actinobacteria, named after Finnish researcher Herman Adlercreutz who pioneered phytoestrogen research. The genus is best known for producing equol, a potent bioactive metabolite derived from dietary isoflavones (soy, legumes), which has anti-estrogenic and antioxidant properties.
Disease Associations
Adlercreutzia is consistently depleted in conditions characterized by estrogen dysregulation and neuroinflammation. In endometriosis, reduced Adlercreutzia abundance correlates with impaired equol production, potentially exacerbating estrogen-driven disease progression ([1]). In multiple sclerosis, dietary interventions targeting the gut microbiome identify Adlercreutzia as a beneficial taxon whose restoration may support anti-inflammatory metabolite production ([2]).
The genus has also been identified in reviews of gut microbiota and male reproductive function, where equol-producing bacteria influence testosterone metabolism and spermatogenesis ([3]).
