From Science Daily

The results of the new study show that a substance found in pomegranates, urolithin A, removes weak mitochondria from the brain just as effectively as NAD supplement.

From Science Daily

"The advantage of working with a natural substance is the reduced risk of side effects. Several studies so far show that there are no serious side effects of NAD supplementation. Our knowledge of urolithin A is more limited, but as I mentioned, clinical trials with Urolithin A have been effective in muscular disease, and now we need to look at Alzheimers disease. ," he says and adds:

From Science Daily

One important problem during sarcopenia is that the cellular cofactor NAD+ declines during ageing, while mitochondria, the energy powerhouses in our cells, produce less energy.

From Science Daily

Providing this molecule in pre-clinical models resulted in increased levels of NAD+, increased mitochondrial activity and contributed to the maintenance of muscle function during ageing.
