The gut microbiome, the community of bacteria that reside in the human gut, has recently emerged as a potential target for improving bone strength. Studies have shown that certain bacteria, such as DTU089, Marvinbryantia, Blautia, Akkermansia, Methanobrevibacter, Lachnospiraceae NK4A136 group, and Faecalibacterium, may influence bone remodelling and density.
Study Links Gut Microbiome to Skeletal Health
A new observational study investigated the relationship between the gut microbiome and bone health. The researchers analysed data from two large cohorts and found that an abundance of certain bacteria, including DTU089, Marvinbryantia, Blautia, and Akkermansia, was associated with lower bone measures. Conversely, higher abundances of Lachnospiraceae NK4A136 group, and Faecalibacterium were linked to greater bone density.
Pathways Linked to Gut Bacteria and Bone Density
The study also revealed associations between the gut microbiome and metabolic pathways involved in bone health. Notably, a higher prevalence of pathways related to histidine, purine, and pyrimidine biosynthesis was associated with a modest increase in tibia bone density.
Implications for Osteoporosis Prevention and Treatment
The findings suggest that the gut microbiome may play a role in bone health and that interventions targeting specific bacteria could potentially be developed for preventing and treating osteoporosis.
