Pomegranate juice has been known for centuries to have health benefits, especially in traditional medicine. Recently, research has discovered a component in pomegranate called urolithin A that has anti-aging properties. Urolithin A has been shown to promote healthy mitochondrial function, which plays a significant role in the aging process.1-5

Mitochondria are tiny organelles within our cells that generate energy in the form of ATP. Mitochondrial dysfunction is a hallmark of aging and age-related diseases. As we age, the efficiency of our mitochondria decreases, and they accumulate mutations and damage. This decline in mitochondrial function leads to cellular damage and ultimately aging-related diseases like Alzheimer's and Parkinson's.6,7

Urolithin A has been shown to promote healthy mitochondrial function by inducing mitophagy, a process by which aging and damaged mitochondria are cleared from the cell. Mitophagy ensures that healthy mitochondria continue to function properly, and damaged ones are removed, preventing further damage to the cell.8

In a study published in the Journal Nutrition, Obesity and Exercise, the authors aimed to investigate whether a natural substance called urolithin A could improve muscle function and biomarkers associated with mitochondrial and cellular health in older adults. The study involved a randomized, double-blind, placebo-controlled trial of 66 adults aged 65 to 90 years, who were assigned to either receive daily oral supplementation of urolithin A or placebo for four months. The researchers assessed the participants' muscle endurance, six-minute walk distance, and maximal ATP production (a measure of energy production in cells) at baseline, two months, and four months. They also analysed plasma biomarkers associated with cellular and mitochondrial health. The results showed that urolithin A supplementation significantly improved muscle endurance (i.e., the number of muscle contractions until fatigue) in two skeletal muscles (the tibialis anterior in the leg and the first dorsal interosseus in the hand) at two months, compared to placebo. Plasma levels of certain biomarkers were also decreased in the urolithin A group compared to placebo at four months. The researchers concluded that urolithin A supplementation was safe and well-tolerated in the older adult population they studied. The findings suggest that urolithin A supplementation may be beneficial for muscle endurance and plasma biomarkers, which could help counteract age-related muscle decline.9

Pomegranate juice powder, which contains urolithin A, is a convenient way to consume this compound. The powder can be added to smoothies, protein shakes, or water. Studies have shown that consuming pomegranate juice can help reduce oxidative stress, lower blood pressure, and improve cholesterol levels.10-12

In addition to its anti-aging properties, urolithin A has also been shown to have other health benefits. It has been linked to the prevention of colon cancer13,14 and neurodegenerative diseases like Alzheimer's and Parkinson's.15-17 Urolithin A also has anti-inflammatory properties and has been shown to reduce inflammation in the body.8,18

In conclusion, urolithin A, found in pomegranate juice powder, has shown promise as an anti-aging compound by promoting healthy mitochondrial function through mitophagy. Mitochondrial dysfunction is a hallmark of aging and age-related diseases, and urolithin A has been shown to improve mitochondrial function in multiple studies. In addition to its anti-aging properties, urolithin A has other health benefits like reducing inflammation and potentially preventing neurodegenerative diseases. Pomegranate juice powder is a convenient way to consume urolithin A and reap its health benefits.
