Mitochondria which converts food into energy, generates adenosine triphosphate (ATP) life-sustaining chemical tissue, and mitophagy which is the process of breaking down old worn out mitochondria. The March 22 2022 Popular Science report says researchers found that Urolithin A boosts mitophagy. It is produced as a by-product when gut bacteria digest specific ingredients such as pomegranates (1).
David Marcinek, Ph.D., a professor of radiology at the University of Washington School of Medicine in Seattlein Medicine News Today, believes that Urolithin A supplements may provide a way to stimulate mitophagy in older people and help them maintain strength and endurance. He and his team are doing preliminary clinical trial to find out the efficacy and safety of such supplements (2).
