The Biochemical Formation of Urolithin A

You may be wondering how urolithin A comes to be. Well, it’s pretty cool! Urolithin A is actually a metabolite formed from the transformation of ellagitannins by our gut bacteria.

Ellagitannins are complex polyphenols found in everyday edible plants like pomegranates, strawberries, raspberries, walnuts, and more. These compounds belong to the class of organic compounds known as benzo-coumarins or dibenzo-α-pyrones.

Now let’s talk all science-y about the process our gut bacteria use to create this wonder compound.

When we consume foods rich in ellagitannins and ellagic acid, these compounds come into contact with our gut bacteria, which work their magic by converting them into urolithin A. In fact, specific strains of Lactobacillus plantarum, such as CCFM1286, CCFM1290, and CCFM1291, are found to help with this conversion.

Here’s a quick breakdown of this process:

  • We eat foods rich in ellagitannins and ellagic acid (like pomegranates, berries, and nuts).
  • Our gut bacteria, mainly Lactobacillus plantarum strains, convert these compounds into urolithin A.
  • We obtain the benefits of urolithin A!

The production of urolithin A is just another amazing example of how our gut microbiome contributes to our well-being. By consuming a diverse and balanced diet, we can fuel our body with essential nutrients and support the growth of friendly gut bacteria, helping us get the most out of these beneficial compounds.

Urolithin A and Dietary Sources

So, what should we put on our plates to ensure we get enough of this fantastic nutrient? Our top recommendations include pomegranates, berries, and walnuts. These tasty superfoods are rich in the polyphenols that our gut bacteria convert into UA.

Now, it’s important to note that UA production depends on the composition of our gut microbiome. This means that not everyone will be able to produce the same amount of Urolithin A. However, don’t worry, direct supplementation with Urolithin A is also an option, so that everyone can consistently benefit from it. Check out all the options on Amazon.
