Azelaic Acid Extended Lifespan in C. elegans Roundworm Study
A study on the roundworm C. elegans found that azelaic acid reduced reactive oxygen species, increased superoxide dismutase activity and extended lifespan, an effect linked to the insulin signaling pathway. The authors suggest it may be an anti-aging candidate.

What the research shows
According to the study on the microscopic roundworm C. elegans, azelaic acid reduced reactive oxygen species, molecules associated with cellular stress, and increased the activity of the enzyme superoxide dismutase. The treated animals lived longer, and the effect was linked to the insulin signaling pathway, a set of processes that regulates metabolism and aging in many organisms. The authors suggest the substance may be an anti-aging candidate.
This kind of research helps explain how aging pathways work, but it is done in very simple animals. Results in worms do not prove effects in people, because worm and human biology differ considerably. Before any conclusion about safety or benefit, studies in more complex animals and then in people are needed.
What it means
The finding suggests that, in worms, azelaic acid was associated with longer life through pathways linked to oxidative stress and insulin. It is still unknown whether something similar happens in mammals or people, or what its safety profile would be.
How to read it with care
A result in worms does not replace a medical consultation. Anyone considering a change in diet, supplements or treatment should talk to a doctor or another qualified professional before deciding.
