Ageing study reveals common supplement could be the secret to staying young
A new study sheds light on how we could turn wind back our biological clock
Scientists might have just revealed the secret to staying young.
According to a new study, a daily dose of one common supplement could turn back the years on our biological clock, keeping our organs younger for longer.
Our biological age is determined by how old our cells and organs are, not by our true age. Scientists now say taking omega-3 every day may slow down your rate of biological ageing.
Blood work revealed that across three years, just one gram of omega-3 ‘turned back the clock’ on biological age by up to four months. Researchers also found that combining omega-3, a vitamin D supplement and exercise worked even better.
Heike Bischoff-Ferrari, the lead author on the study and professor of geriatric medicine and healthy longevity at the University of Zurich, said: “While the effects may appear small with three to four months rejuvenation of biological age in three years, if sustained, they may have relevant effects on population health.”

That said, the study could lead to future research on reversing ageing.
Previous research by the same team found that taking omega-3 slashed the rate of infection by 13 per cent and the rate of falls by 10 per cent. The trio of interventions also cut the incidence of invasive cancer by 61 per cent after a three-year follow-up.
In the current study, researchers used biological tools called epigenetic clocks to measure ageing across nearly 800 people aged 70 and over. Participants were divided into eight groups and given either a gram of algae-based omega-3 a day, the recommended daily dose of vitamin D, did 30 minutes of exercise three times a week, or a combination.
Omega-3 slowed ageing in three different clocks, whereas the trio of omega-3, vitamin D and exercise slowed ageing in four clocks.
Bischoff-Ferrari and Steve Horvath, another author in the study, say they take omega-3 and vitamin D supplements daily to ward off ageing-related health issues. “I do this every morning with my coffee,” says Horvath, “I practise what we publish.”

However, Prof Kevin McConway, Emeritus Professor of Applied Statistics and the Open University warns the research is in its early stages and there is “so much that it can’t tell us.”
“They mention that they don’t have data on long-term survival rates of the people in the study. Maybe one of the other clocks will eventually turn out to relate more closely to survival rates and future health. Maybe the pattern of how the effects of the three interventions combine will be different. We just can’t say yet,” said Prof McConway.
“Also we can’t say whether the effect on biological aging clocks will continue after three years, because that wasn’t studied. Maybe taking omega-3 supplements for longer will have a greater impact on biological aging, or maybe it won’t. And the study doesn’t indicate what the effect on these biological clocks would be if people, who had been taking a supplement, stop taking it,” McConway added.
The study was published in the journal Nature Ageing.
