The Claim

In C57BL/6 male mice fed a high-fat diet, consumption of Reb M is associated with an increased abundance of the colonic Lachnospiraceae bacterial family (ASV16228, p<0.001) and elevated plasma butyrate levels compared to control groups receiving water or fructose.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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

In plain English

When male mice eat a fatty diet and drink something called Reb M instead of water or sugar water, their gut bacteria called Lachnospiraceae grow more, and they have more butyrate in their blood — a chemical that’s good for gut health.

In C57BL/6 male mice on a high-fat diet, Reb M consumption was associated with increased abundance of the colonic Lachnospiraceae bacterial family (ASV16228, p<0.001) and elevated plasma butyrate levels compared to water and fructose controls.

  1. Study: Long-term metabolic effects of non-nutritive sweeteners

    The study gave mice a sweetener called Reb M and found it increased good gut bacteria linked to healthy fats — which matches what the claim says.
