Pomegranate By-Product, UA, Shown to Fight Aging in New Study

Urolithin A (UA) is a chemical by-product that is made by our bodies when we consume pomegranate juice, strawberries or walnuts. Johan Auwerx at the École Polytechnique Fédérale de Lausanne in Switzerland and his team wanted to investigate whether these foods are as beneficial to health as some have suggested, so they decided to test the effects of UA in rodents and worms.

When they gave UA to Caenorhabiditis elegans worms, the animals lived an average of 45 per cent longer. And when the team gave the chemical to elderly mice, they could run 42 per cent further. This improvement occurred in the mice without them building any more muscles, which suggests that UA improves muscle-cell quality, rather than quantity.


When Auwerx’s team looked closer, they found that UA seems to improve muscle cells by triggering them to eliminate damaged mitochondria – the powerhouses of the cell. When these are purged, the remaining healthy mitochondria divide and multiply. This means that they can produce more energy and work more efficiently.

“The goal is to see if this could be a potential therapy for frail elderly people,” says Auwerx.


As we get older, our muscle function declines, leading to frailty and loss of mobility. Loss of muscle mass – called sarcopenia – is increasingly being seen as an important factor in ageing, prompting several researchers to look for treatments that can protect or repair muscles.

Auwerx thinks that UA is the only chemical discovered so far that is capable of building better muscles: other experimental treatments focus instead on building more muscle. His team is now conducting a clinical trial of the compound in people to see whether it can reduce frailty as they age.

If UA affects mitochondria in both worms and rodents, the odds are that this might work for other mammals too, says Nate Szewczyk at the University of Nottingham in the UK. “The promise for this having an effect in humans is very real.”

So should you start guzzling pomegranates? Auwerx suggests that drinking pomegranate juice and eating more berries and nuts may be advantageous for health. However, team member Chris Rinsch estimates that a person would have to drink up to four large glasses of pomegranate juice every day to receive an equivalent dose of UA to that they gave to rats in their study.

Epitalon and the mitochondria

For decades, through study after study, Epitalon (Epithalon) has been linked to an increase of length, and health of telomeres, at the end of DNA strands.

A very good reason to keep our telomeres long is their influence on the mitochondrial part of our cells, the power plant in our cells. Science has demonstrated that too short telomeres induce the death of the cell, but also compromises the mitochondria previous to that.

Telomeres dysfunction, due to their progressive shortening, disturbs mitochondria functions and reduces energy production, increases free-radical production, and utlimately starts the cell’s self-destruction.

Epitalon_Telomerase_longevite_web-300x201Keeping long and healthy telomeres is the most important step anyone can take to stop and hope to reverse aging, as without long telomeres cells can’t live nor duplicate, nor even produce energy to supply to our body!

With Epitalon, one can begin to apply these findings immediately, because it's available now through OceansLab.
