Phenols

Phenols are organic compounds that can be produced by gut bacteria during the fermentation of certain amino acids, particularly tyrosine. Some phenols, such as p-cresol, may have toxic effects in high concentrations and are associated with dysbiosis or imbalances in gut microbiota. Elevated phenol levels in stool can reflect microbial activity that may place strain on the liver’s detoxification systems. Monitoring phenols helps assess how well the gut is managing protein breakdown and microbial fermentation processes.

Description

What are phenols in relation to gut health?

Phenols are compounds produced by gut bacteria during protein fermentation, particularly from tyrosine.

Why are phenols measured in faeces?

To assess microbial fermentation activity and potential imbalances or dysbiosis in the gut.

Are high phenol levels something to be concerned about?

Yes, elevated phenols can be toxic and may indicate microbial overgrowth or a strain on detoxification pathways.

What factors can influence phenol production in the gut?

Diet (particularly high-protein intake), gut microbiota composition, and intestinal transit time can all affect phenol levels.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
