The Claim

Daily supplementation with 30 billion pasteurized Akkermansia muciniphila cells for 4 months significantly reduces trunk and android fat mass in adults with metabolic syndrome and low baseline levels of Akkermansia muciniphila.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In adults with metabolic syndrome and low levels of Akkermansia muciniphila, taking 30 billion pasteurized cells of this bacterium daily for four months reduces fat around the trunk and abdomen.

See the scientific wording

In adults with metabolic syndrome and low baseline Akkermansia muciniphila levels, daily supplementation with 30 billion pasteurized cells for 4 months significantly reduces trunk and android fat mass, indicating a targeted effect on visceral adiposity that may contribute to improved metabolic health.

Why this might work

Bacteria-derived proteins from pasteurized Akkermansia muciniphila bind to receptors in the gut lining, strengthening the barrier that prevents harmful substances from leaking into the bloodstream. This reduces chronic inflammation in fat tissue, especially around the abdomen. At the same time, these proteins trigger gut cells to release a hormone that improves how the body uses insulin, leading to less fat storage in the trunk and waist area.

  1. Study: Effect of pasteurized Akkermansia muciniphila MucT on insulin sensitivity, body composition, and GLP-1 production in subjects with metabolic syndrome: impact of low baseline gut Akkermansia levels

    People with metabolic syndrome and low gut Akkermansia who took a daily supplement of this bacteria lost more belly fat than those who didn’t — but only if they started with very little of it. The study confirms this specific group benefited.
