Urolithin A

What is Urolithin A?

Urolithin A is a substance produced by the body after consuming foods rich in polyphenols, such as berries, nuts, and especially pomegranates. It is a postbiotic, meaning that it is a byproduct of bacteria in our gut microbiome metabolizing dietary polyphenols. Postbiotics, such as urolithin A, are considered to have potential health benefits.

How is urolithin-A produced?

• The process begins with the consumption of foods rich in ellagitannins, a type of polyphenol.
• Intestinal bacteria, particularly those in the Clostridiales and Ruminococcaceae families, convert ellagitannins to urolithin A.
• Not everyone can produce urolithin A, because the composition of the gut microbiome varies greatly from person to person due to factors such as diet, genetics and age.

Fact: Only 1 in 3 people produce sufficient Urolithin A themselves.

In which foods do you find it?

Urolithin A itself is not directly found in food. Instead, the body converts certain nutrients, such as ellagitannins, into urolithin A. Pomegranate is one of the best-known foods rich in ellagitannins, but berries and nuts also contain these compounds.

Major dietary sources of ellagitannins:

• Pomegranate
• Strawberries
• Raspberries
• Walnuts
• Almonds

Although these foods contribute to the production of urolithin A, the amount the body can produce on its own is often limited.

Supplements with Urolithin A

Because not everyone can produce enough through food alone, supplements can be a solution. This supplement from Hansen contains high-quality urolithin A, which ensures that you get the optimal amount.

Why choose Urolithin A supplements?

• Not everyone produces enough: Only one third of people can get enough urolithin A from food.
• Effective dosage: Supplements ensure that you get urolithin A consistently and in sufficient quantities, without being dependent on the functioning of your intestinal microbiome.

Benefits

Urolithin A Supplement Dosage

The recommended daily dose is between 100 mg and 1000 mg per day. This is up to 6 times the amount the body can produce through natural food. It is important to note that supplements are not a replacement for a healthy diet and lifestyle, but a supplement to it.

Dosage overview:

In many scientific studies, a dosage of 500-700mg per day used. This amount is often considered effective for researching the potential benefits of the supplement. While the ideal dosage can vary from person to person depending on factors such as age, health, and individual needs, this is the most common dosage in studies.

If you are considering using urolithin A, it may be useful to start with a dose in this range unless otherwise advised by a doctor or specialist.

Why is Urolithin A so expensive?

The high price is due to the complex production processes. It cannot be extracted directly from food, but must be synthesized via a biochemical process. This requires advanced technologies and purification techniques that increase production costs.

Reasons for the higher costs:

• Advanced production methods: Synthesis and purification of urolithin A are technically challenging and expensive.
• Limited availability: There are only a few suppliers offering urolithin A, which limits demand and increases the price.

Conclusion

Urolithin A is an important postbiotic that is produced by the body after eating certain polyphenol-rich foods. Because only a small percentage of people can produce sufficient urolithin A, supplements can be a valuable addition to help ensure optimal levels. While these supplements are more expensive due to the complexities involved in manufacturing, they can be an effective way for many to support their health.
