Research has reported that a substance called Urolithin A in pomegranates and other fruits may help slow certain aging processes by improving the function of mitochondria in cells; in addition, consuming this chemical compound poses no risk to human health. Studies have shown that Urolithin A can stimulate mitochondrial biogenesis in a way that is similar to regular exercise, and is the only compound that can restore the cell's recycling of defective mitochondria.
