The Claim

In C57BL/6 male mice fed a high-fat diet for 20 weeks, consumption of Reb M is associated with improved insulin sensitivity compared to water and fructose controls, as evidenced by lower insulin tolerance test AUC (p=0.03) and reduced C-peptide levels, suggesting enhanced insulin action without increased insulin secretion.

What the research says

Supports is higher

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

In plain English

When mice on a fatty diet drank a sweetener called Reb M instead of water or sugar water, their bodies handled insulin better—meaning their blood sugar stayed more under control without making more insulin.
