Urolithin A is a dietary supplement containing urolithin A, a metabolite studied in the fields of cellular health and anti-ageing.
This particularly innovative ingredient is attracting scientific interest because of its potential effects on mitochondrial and cellular function, and thus its ability to maintain young-looking skin and support overall longevity, etc. (1)
The supplement Urolithin A is part of our longevity product category.
Urolithin A is a metabolite produced naturally by the body from the conversion by gut bacteria of dietary ellagitannins and ellagic acid (it is often described as a postbiotic).
Ellagitannins and ellagic acid are found at low levels in fruits such as pomegranates, blackberries, nuts...
Urolithin A has been the subject of numerous studies investigating its potential to support:
As a reminder, mitochondria are responsible for producing ATP, the primary source of cellular energy which the body needs in order to function properly and survive.
Mitochondrial dysfunction plays a key role in the ageing process and subsequent development of age-related health problems (metabolic, degenerative...)
Taking a pure urolithin A supplement enables you to:
Our urolithin A supplement stands out from other ‘anti-ageing’ and similar products in 6 key facets:
Mitophagy is an autophagic process through which a healthy-functioning body eliminates and recycles dysfunctional and senescent mitochondria from its cells.
When mitophagy ceases to function properly, it can lead to the accumulation of dysfunctional mitochondria, impair cellular health and promote the development of age-related health problems.
Scientists are therefore interested in urolithin A for its potential to induce mitophagy.
Scientists have identified urolithin A as a potentially powerful activator of the PINK1/parkin mitophagy pathway (PINK1 being a kinase-1 induced by PTEN, the phosphatase and tensin homolog).
This pathway leads to selective ubiquitination (the marking by ubiquitin molecules) of targeted mitochondrial proteins, and then to their elimination by phagolysosomes : the ‘tagged’ proteins are enclosed in phagosomes fused with lysosomes in order to be broken down by enzymes.
Urolithin A may also be able to activate several pathways independent of PINK1/parkin to eliminate defective mitochondria (10).
Besides taking a urolithin A supplement, you can increase your intake by ingesting the metabolite’s precursors: ellagitannins (bioactive polyphenols) and ellagic acid (an ellagitannin derivative).
Ellagitannins and ellagic acid can be digested and metabolised into A and B urolithin by gut microbiota bacteria, in the small intestine and colon.
However, supplementing directly with urolithin A avoids this somewhat unreliable conversion stage and allows you to benefit directly from substantial amounts of the ‘end product’ itself.
If, however, you’d prefer to consume ellagitannins and ellagic acid, there are a number of foods that contain them:
The increased interest in urolithin A capsules for promoting healthy ageing is supported by 2 key factors:
A significant proportion of the population is therefore unable or ill-equipped to convert ellagitannins and ellagic acid into urolithin A, in order to prevent the accumulation of dysfunctional mitochondria. The only way such individuals can benefit from this active ingredient’s properties is to take a supplement.
In combination with your urolithin A supplementation, we’d recommend taking substances associated with mitochondria, such as pyrroloquinoline quinone (PQQ), R-lipoic acid and acetyl-L-carnitine. These can be found combined in certain synergistic formulations (such as the supplement Mitochondrial Formula).
Again related to cellular health, you could also benefit from compounds studied for their potential to suppress damaging senescent or ‘zombie’ cells that collect in the body over time. These potential natural ‘senolytics’ (senescent cell-eliminators) include fisetin (try the supplement Fisetin), quercetin, decaffeinated black tea, bromelain... (the best of these compounds have been brought together in the synergistic formulation Senolytic Complex).
