Description: 3,8-dihydroxy-6H-dibenzo[B,D]pyran-6-one is also called urolithin A. Studies have reported that a substance called urolithin A in pomegranates and other fruits may help slow down the specific aging process by improving the function of cell mitochondria; in addition, the intake of this compound does not pose a risk to human health. Studies have shown that urolithin A can stimulate mitochondrial biogenesis in the same way as regular exercise and is the only compound that can restore the cell's recycling of defective mitochondria.
