The Claim

Supplementation with probiotic VSL#3 in mice fed a high-fat diet reduces weight gain, improves glucose tolerance, lowers liver enzyme levels, and decreases intestinal permeability, with these effects being partially dependent on Nfil3 signaling.

How it works
1 study reviewed
In plain English

In mice eating a high-fat diet, taking the probiotic VSL#3 leads to less weight gain, better blood sugar control, lower liver enzyme levels, and reduced intestinal leakage, and these changes require part of the Nfil3 signaling pathway.

See the scientific wording

Probiotic VSL#3 supplementation in mice on a high-fat diet reduces weight gain, improves glucose tolerance, lowers liver enzymes, and decreases intestinal permeability, effects that are partially dependent on Nfil3 signaling.

Why this might work

The probiotic VSL#3 increases beneficial gut bacteria that produce short-chain fatty acids. These fatty acids block a protein called Nfil3, which normally disrupts the gut lining and liver metabolism. When Nfil3 is blocked, the gut lining repairs itself, preventing harmful bacteria from entering the bloodstream. This stops liver inflammation and allows the liver to properly process fats and sugars, reducing fat buildup and improving blood sugar control.

    Giving this special probiotic mix to mice eating junk food helped them stay healthier—gaining less weight, better blood sugar, and less liver damage—but only if they had a specific gene called Nfil3. Without that gene, the probiotic didn’t work as well.
