Healthy microbiome: a focus on Roseburia

Healthy microbiome: a focus on Roseburia

Body composition & metabolism

Unlike its more famous counterparts Lactobacillus and Bifidobacteria, Roseburia is a bacteria slightly less represented, that still plays a major role in the gut microbiome. This core genus counts for 3-15% of the total bacterial in a healthy gut (1).

Roseburia is a butyrate producer,

playing then a key role

in the energy production.

Roseburia spp. are part of commensal bacteria producing short-chain fatty acids, especially butyrate produced after the fermentation, or breaking down, of indigestible dietary carbs (e.g. fibers) (2). Butyrate is a key factor in the interactions between us and Roseburia.

Roseburia levels

in the gut are often

linked to good health.


Roseburia spp. play, primarly through SCFAs production, an important role in colonic mobility, in the control of gut inflammatory processes (3), and in the maturation of the immune system (4).

Modification in Roseburia spp. representation may affect various metabolic pathways and, as a health marker, the reduction of Roseburia spp. are associated with several diseases (including irritable bowel syndrome, obesity, type 2 diabetes, nervous system conditions, and allergies) (1).


A targeted dietary intervention may contribute to the promotion of healthy Roseburia spp in the gut (5).
