Urolithin A is a metabolic product of the ellagitannins prevalent in pomegranate, red and black berries, as well as other pigmented fruit the chemical formula for Urolithin A is C₁₃H₈O₄. This formula indicates that each molecule of Urolithin A contains 13 carbon atoms, 8 hydrogen atoms, and 4 oxygen atoms. Ellagitannins are metabolized by intestinal microorganisms to ellagic acid, which is the immediate precursor of the family of urolithins. Urolithin A may help protect against cellular damage caused by inflammation and reactive oxygen species (ROS) Mitochondrial health Urolithin A may improve mitochondrial function and increase mitophagy, which can help with cellular health. Muscle health Urolithin A may promote muscle protein synthesis and growth, and help with muscle atrophy helps with weight loss by improving insulin sensitivity and reducing inflammation and fatty liver. Urolithin A is a metabolite produced by the gut microbiota when ellagic acid and ellagitannins are consumed in food. These compounds are found in berries, nuts, and pomegranate. However, only about 40% of people can naturally convert these compounds into UA at meaningful levels.Experimental models consistently show that UA increases mitophagy and mitochondrial function and blunts excessive inflammatory responses. Urolithin A increased biomarkers of mitochondrial function in preclinical models of aging and in healthy elderly people. UA is a promising strategy to target health and disease conditions of aging, especially those linked to mitochondrial and muscle dysfunction. Urolithin A is better than Rhubarb
