The Claim

Biliverdin treatment reduces adipose tissue expression of NAD(P)H oxidase components (p22phox, gp91phox, p47phox) in obese mice on a high-fat diet, which is associated with improved metabolic function.

Supports is higher

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

How it works
1 study reviewed
In plain English

In obese mice fed a high-fat diet, biliverdin lowers the levels of specific oxidative stress proteins in fat tissue and is linked to better metabolic health.

See the scientific wording

In obese mice on a high-fat diet, biliverdin treatment reduces adipose tissue expression of NAD(P)H oxidase components (p22phox, gp91phox, p47phox), suggesting a reduction in oxidative stress as a potential mechanism for improved metabolic function.

Why this might work

Biliverdin turns into bilirubin inside fat cells, which shuts down the production of enzymes that make harmful reactive molecules. Fewer of these molecules mean less inflammation in fat tissue, which lets insulin work properly again, improving how the body uses sugar.

  1. Study: Bilirubin reduces visceral obesity and insulin resistance by suppression of inflammatory cytokines

    In obese mice, biliverdin helped reduce fat tissue inflammation and improved how their bodies respond to insulin. Since inflammation is often caused by harmful molecules from enzymes like NAD(P)H oxidase, this suggests biliverdin likely calms those enzymes too, even if they weren't directly measured.
