March 9 (UPI) — A daily multivitamin may slow biological aging — the rate at which our bodies age on a cellular level — significantly, especially for people biologically older than their actual age.

Researchers at Harvard Medical School and Mass General Brigham found that daily cocoa extract and multivitamin slowed biological signals that are predictive of mortality, they write in a study published in the journal Nature Medicine.

Epigenetic clocks can estimate biological aging based on changes in DNA by looking at sites that regulate gene expression and change as people age.

By monitoring these signals, it is possible to track mortality and the pace of aging, as well as the predict it.

“There is a lot of interest today in identifying ways to not just live longer, but to live better,” Howard Sesso, lead author of the study,” said in a news release.

“This study opens the door to learning more about accessible, safe interventions that contribute to healthier, higher-quality aging,” said Sesso, preventive medicine specialist at Mass General and epidemiologist at the Harvard Chan School of Medicine.

Using data from the Cocoa Supplement Multivitamins Outcomes Study, the researchers analysed DNA changes in blood samples from 958 randomly selected healthy study participants who had an average actual age of 70.

The participants were randomized to take daily cocoa extract and a multivitamin, cocoa and a placebo, placebo and multivitamin or only placebo for two years, with researchers analyzing five epigenetic clocks in blood samples from the study’s start, at the end of the first year and at the end of the second year.

Overall, compared to the placebo-only group, those taking a multivitamin saw a statistically significant slowing of biological aging by about four months — especially for those who were biologically older than their age when the study started.

The researchers also found that cocoa extract had no effect on biological aging.

While the results are promising, the researchers concluded in the study that additional work is needed to better determine the clinical relevance of multivitamins on biological aging.

“We plan to do follow-up research to determine if the slowing of biological aging — observed through these five epigenetic clocks, and additional or new ones — persists after the trial ends,” Yanbin Dong, study co-author and researcher at the Medical College of Georgia, Agusta University, said in the release.

DIANNE Buswell has shown off her blossoming baby bump after being forced to shut down rumours she’d secretly given birth.

Strictly star Dianne and long-term partner Joe Sugg jokingly shut down the rumours after an AI photograph of them cradling a baby was spread online.

The photograph was so realistic that family and friends had reached out to them to “congratulate them”, albeit confused they hadn’t been told.

Today, Dianne showed off her classic jokey charm with a TikTok video set to a sound clip from Friends.

In the video, Dianne pushes a baby stroller in front of the camera, while wearing a bright green jacket.

She then whips it back to reveal her bare baby bump in a sports bra and leggings and declares: “That’s right, still no baby!”

Dianne then covers the bump back up with the jacket and struts out of shot.

This isn’t the first time Dianne has combatted the internet with a comedic take, previously hitting back at trolls who questioned why her baby bump is always on-show.

She shared a TikTok video over the top of which she’d written one of the remarks: “But why do you always have your belly out?”

She had KC and the Sunshine Band’s That’s the Way (I Like It) playing in the background, as she captioned the video: “Because that’s the way I like it!”

Joe and Dianne announced they were expecting their first baby last September, shortly before Dianne returned to the dancefloor for Strictly Come Dancing 2026.

The returning champion dancer was partnered with Neighbours actors Stefan Dennis, however unfortunately the pair were forced to withdraw in week four because he sustained an injury.

Her participation made Strictly history as she was the first pro to compete while pregnant.

Dianne and Joe met thanks to the BBC competition, as they were partnered together on the sixteenth series of the show back in 2018.

They proved to be an impressive partnership as they managed to make it all the way to the final before falling at the final hurdle and losing out to Stacey Dooley and Kevin Clifton.

They confirmed their relationship shortly after, with Joe declaring in an Instagram post that he’d “got something better than the glitterball”.
