Now, Saudi Arabia is throwing it a lifeline. For nearly a decade, molecular biologist Johan Auwerx fought to get investors to back his theory that Urolithin A – a natural compound produced by our gut bacteria from food such as pomegranates and walnuts – holds the key to healthy ageing. In 2016, Nature published a study led by Auwerx, a professor in energy metabolism at the Swiss Federal Institute of Technology Lausanne (EPFL), showing that Urolithin A stimulates mitophagy, a process that clears out old or damaged mitochondria from our cells, and helps maintain muscle function as we age.

Although Auwerx secured grants and minor ...
