Two people can eat the identical bowl of pomegranate seeds and only one receives the anti-aging payoff — the difference comes down to a set of gut bacteria the majority of us simply don’t carry

Source Summary

Only a specific set of gut bacteria — Gordonibacter and Ellagibacter species — can convert pomegranate ellagitannins into urolithin A, the molecule longevity researchers link to mitochondrial repair. Most adults don't carry enough of them, which means the same bowl of seeds delivers real anti-aging chemistry to one person and almost nothing to another.
