Citrulline and age-related fat buildup in C. elegans worms
In a study of the C. elegans worm, more citrulline was linked to more age-related lipid buildup and a shorter lifespan. This is animal research, not yet shown to apply to people.

What the research shows
The study of the tiny C. elegans worm indicated that citrulline, a metabolite, drives age-related lipid buildup. When the worms had less citrulline, this buildup decreased, but their lifespan also became shorter. According to the source, the effect observed was reversed with dietary supplementation in the animals.
Because this is animal research, the results do not directly show what happens in people. C. elegans is a simple organism widely used in laboratories to study aging, but its metabolism differs from human metabolism in many ways. Findings like this generate hypotheses that must be tested in studies with people before any conclusion about health can be drawn.
What it means
The finding suggests that a metabolite may influence aging and lipid buildup in an animal model. It is still unknown whether the same happens in people, or how clinically important this would be.
