The Claim

Apigenin increases intracellular NAD+ levels in mouse cells and tissues in a CD38-dependent manner, as evidenced by the absence of this effect in CD38 knockout cells.

Supports is higher

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

How it works
1 study reviewed
In plain English

Apigenin raises the amount of NAD+ inside mouse cells and tissues, and this increase requires the presence of the CD38 protein.

See the scientific wording

Apigenin increases intracellular NAD+ levels in mouse cells and tissues in a CD38-dependent manner, as evidenced by the absence of this effect in CD38 knockout cells.

Why this might work

Apigenin blocks the enzyme that breaks down NAD+, causing NAD+ to build up inside cells. More NAD+ means the cell can activate processes that use it, like repairing DNA and regulating metabolism.

  1. Study: Flavonoid Apigenin Is an Inhibitor of the NAD+ase CD38

    Apigenin boosts NAD+ levels in mouse cells by blocking the CD38 enzyme that breaks down NAD+. If CD38 isn’t there, apigenin can’t work — so it only raises NAD+ when CD38 is present.
