Urolithin A, a metabolite of ellagitannins in pomegranates, boosts immune cells’ ability to combat tumors by inducing a process known as mitophagy. STORY AT-A-GLANCE Urolithin A (UA) has emerged as a powerhouse player in the fight against cancer, as it may naturally boost tumor-fighting immune cells. UA is a metabolite of ellagitannins in pomegranates that has anti-inflammatory and anticancer effects. UA “recycles and renews mitochondria” by inducing a biological pathway known as mitophagy—the process of cleaning out your mitochondria, allowing them to function at their best. This changes T cells’ genetic program, making them more able to fight tumors. In...
