Abstract: A brand new research finds that urolithin A, a substance present in pomegranates, can enhance reminiscence and should assist deal with Alzheimer’s illness. This pure compound works by eradicating broken mitochondria from the mind, much like the consequences of NAD dietary supplements. Whereas dosage remains to be being decided, this discovery provides promising potential for treating and stopping neurodegenerative ailments.
Key Details:
- Urolithin A, present in pomegranates, improves reminiscence and should alleviate Alzheimer’s signs
- This substance removes broken mitochondria from the mind, much like NAD dietary supplements.
- Urolithin A is obtainable in capsule type, and researchers are working to find out optimum dosage.

A substance naturally occurring in pomegranates, strawberries and walnuts can enhance reminiscence and therapy of Alzheimer’s illness, a brand new research performed on the College of Copenhagen concludes.
Forgetfulness, problem discovering phrases and confusion about time and place. These are a few of the most typical signs of Alzheimer’s illness.
Now researchers on the College of Copenhagen have found that an strange fruit may help.
“Our research on mouse fashions with AD exhibits that urolithin A, which is a naturally occurring substance in ia pomegranates, can alleviate reminiscence issues and different penalties of dementia,” says Vilhelm Bohr, who’s Affiliate Professor on the Division of Mobile and Molecular Drugs. on the College of Copenhagen and beforehand Division Chair on the US Nationwide Institute on Ageing.
That is excellent news for sufferers with dementia – a illness that’s tough to deal with.
“Despite the fact that the research was performed on mouse fashions, the prospects are optimistic. Up to now, analysis has proven promising outcomes for the substance within the muscle tissue, and scientific trials on people are being deliberate.”
substance improves mind perform
The researchers beforehand found {that a} particular molecule, nicotinamide riboside (NAD complement), performs a key function in neurodegenerative ailments reminiscent of Alzheimer’s and Parkinson’s, because it actively helps take away broken mitochondria from the mind.
“Many sufferers with neurodegenerative ailments expertise mitochondrial dysfunction, also referred to as mitophagy. Which means that the mind has difficulties eradicating weak mitochondria, which thus accumulate and have an effect on mind perform.
“If you’ll be able to stimulate the mitophagy course of, eradicating weak mitochondria, you will note some very optimistic outcomes,” Wilhelm Bohr explains.
The outcomes of the brand new research present {that a} substance present in pomegranates, urolithin A, removes weak mitochondria from the mind simply as successfully as NAD complement.
Potential preventive impact
The researchers nonetheless do not know the way a lot urolithin A is required to enhance reminiscence and alleviate signs of Alzheimer’s.
“We nonetheless can not say something conclusive in regards to the dosage. However I think about that it’s greater than a pomegranate a day. Nonetheless, the substance is already obtainable in capsule type, and we’re at present looking for the suitable dosage,” Vilhelm Bohr says.
He additionally hopes the substance can be utilized for preventive functions with no vital uncomfortable side effects.
“The benefit of working with a pure substance is the decreased danger of uncomfortable side effects. A number of research to date present that there are not any severe uncomfortable side effects of NAD supplementation.
“Our information of urolithin A is extra restricted, however as I discussed, scientific trials with Urolithin A have been efficient in muscular illness, and now we have to take a look at Alzheimers illness. ,” he says and provides:
“If we’re going to eat one thing sooner or later to cut back the chance of Alzheimer’s, which we speak loads about, we’ve to verify there are not any vital uncomfortable side effects.”

“Urolithin A improves Alzheimer’s illness cognition and restores mitophagy and lysosomal features” by Vilhelm Bohr et al. Alzheimer’s & Dementia
Summary
Urolithin A improves Alzheimer’s illness cognition and restores mitophagy and lysosomal features.
Background
Compromised autophagy, together with impaired mitophagy and lysosomal perform, performs pivotal roles in Alzheimer’s illness (AD). Urolithin A (UA) is a intestine microbial metabolite of ellagic acid that stimulates mitophagy. The consequences of UA’s long-term therapy of AD and mechanisms of motion are unknown.
METHODS
We addressed these questions in three mouse fashions of AD with behavioral, electrophysiological, biochemical, and bioinformatic approaches.
RESULTS
Lengthy-term UA therapy considerably improved studying, reminiscence, and olfactory perform in several AD transgenic mice. UA additionally decreased amyloid beta (Aβ) and tau pathologies and enhanced long-term potentiation. UA induced mitophagy by way of rising lysosomal features. UA improved mobile lysosomal perform and normalized lysosomal cathepsins, primarily cathepsin Z, to revive lysosomal perform in AD, indicating the crucial function of cathepsins in UA-induced therapeutic results on AD.
CONCLUSIONS
Our research highlights the significance of lysosomal dysfunction in AD etiology and factors to the excessive translational potential of UA.
