Research conducted on mice modeling Alzheimer’s disease has shown promising results regarding the potential benefits of urolithin A, a substance found in foods like pomegranates, strawberries, and walnuts. Scientists have found that urolithin A helps restore the ability to detect and remove damaged cells in the brain, which could have significant implications for treating neurodegenerative diseases such as Alzheimer’s.
One of the key findings of the research is the relationship between urolithin A and mitophagy, the process through which cells detect and remove damaged mitochondria. Mitochondria are essential for providing energy to cells, and when they become damaged, it can lead to the accumulation of cellular waste, affecting brain function. By stimulating the mitophagy process, urolithin A helps in removing weak mitochondria, thus preventing the buildup of molecular debris that is often associated with neurodegenerative diseases.
In the study conducted on mice with a model of Alzheimer’s disease, researchers found that long-term treatment with urolithin A led to improvements in learning, memory, and the sense of smell. Urolithin A was also found to affect the protein cathepsin Z, which is known to be overactive in Alzheimer’s brains and play a role in inflammation. By limiting the production of this protein, urolithin A helped restore certain cellular processes that are responsible for breaking down biological waste in the brain.
While supplements like urolithin A may not prevent or cure neurodegenerative diseases like Alzheimer’s, the research suggests that they could help in slowing disease progression by aiding the body in cleaning up molecular debris. The advantage of using natural substances like urolithin A is the reduced risk of side effects, as demonstrated by previous studies on NAD supplementation. Clinical trials with urolithin A have shown effectiveness in treating muscular diseases, and researchers are now exploring its potential benefits for Alzheimer’s disease.
Although the results of the study are based on mice models, researchers are optimistic about the potential of urolithin A in treating neurodegenerative diseases in humans. Clinical studies are needed to confirm these findings and determine the appropriate dosage for therapeutic purposes. While eating pomegranates and strawberries may not have a significant impact on cognitive health, the research opens up new possibilities for developing novel treatments for conditions like Alzheimer’s. As the lead researcher Vilhelm Bohr states, “Even though the study was conducted on mouse models, the prospects are positive. We still cannot say anything conclusive about the dosage. But I imagine that it is more than a pomegranate a day.”
