Not solely can the drug metformin assist to successfully handle kind 2 diabetes, however it might additionally give older girls a greater probability of residing to the grand outdated age of 90, in response to analysis printed in 2025 – thanks, it appears, to quite a lot of anti-aging results.
Scientists within the US and Germany used knowledge from a long-term US examine of postmenopausal girls. Data for a complete of 438 individuals had been chosen – half of whom took metformin to deal with diabetes, and half who took a distinct diabetes drug, sulfonylurea.
Whereas there are some caveats and asterisks to the examine, these within the metformin group had been calculated to have a 30 % decrease danger of dying earlier than the age of 90 than these within the sulfonylurea group.
“Metformin has been proven to focus on a number of pathways of getting older and due to this fact has been postulated as a drug which will lengthen human longevity,” write the researchers of their printed paper.
“We discovered that metformin initiation elevated distinctive longevity in contrast with sulfonylurea initiation amongst girls with kind 2 diabetes.”
Metformin has been round for many years and is taken into account a gerotherapeutic: a drug in a position to decelerate varied getting older processes within the physique. For instance, it has been proven to restrict DNA harm and promote gene exercise related to lengthy life.
Earlier research have proven that metformin can put the brakes on put on and tear within the mind and even scale back the chance of lengthy COVID. Nevertheless, scientists aren’t but positive that the drug extends lifespan, particularly in people – which is a part of the rationale for this examine.
This analysis cannot show trigger and impact like a randomized managed trial (RCT) may, as a result of the contributors weren’t randomly assigned to 1 remedy or the opposite – fairly, they had been following skilled recommendation. What’s extra, there wasn’t a placebo group that acquired no remedy. The general pattern measurement wasn’t significantly massive, both.
The examine additionally has its strengths – for instance, the typical follow-up interval was 14 to fifteen years, extending far past the size a regular RCT would be capable to. That is necessary to know how any intervention impacts lifespan.
“A key benefit of our evaluation was the lengthy follow-up interval after remedy initiation enabled by examination of a cohort with intensive follow-up from midlife to ages 90 and older, which isn’t possible in typical randomized managed trials,” write the researchers.
RCTs might observe additional down the road to dig deeper into these outcomes, the researchers recommend. Within the meantime, as the worldwide inhabitants continues to skew older, research proceed to seek out methods to hold us more healthy for longer and reduce harm to the physique as we age.

“The geroscience speculation posits that organic getting older is malleable and that slowing organic getting older could delay or stop the onset of a number of age-related ailments and incapacity,” write the researchers.
“A key objective of geroscience is to determine novel therapeutic and preventive interventions that gradual organic getting older.”
The analysis has been printed within the Journal of Gerontology: Medical Sciences.
