News & Views on Systemic Body Odor and Halitosis such as trimethylaminuria TMAU. If you have fecal odors or bowel odors it may be metabolic/systemic

23 April 2018

Paper : TMAO converts back to TMA by bacteria

New paper :
Metabolic retroconversion of trimethylamine N-oxide and the gut microbiota.
Reading Uni UK.

About :
How some gut bacteria can break down TMAO back to TMA.

Full paper : Link

Significance to TMAU :
Probably not that significant as most gut TMAO in humans would likely be from eating fish. Fresh fish contain a lot of TMAO.
Not unless the TMAO comes back from the blood into the bowel.
This would be known as TMAO reduction (to TMA).
Probably not the same as cleaving TMA from choline etc.

Main reason for posting the paper is bits and pieces of mild interest.
Not read the paper proper so the points below may be inaccurate.

Possible interesting points re TMAU

It says :
Enterobacteriaceae are the main TMAO reducers ?
Most of the TMA creation was around the lower small intestine and cecum, not the colon ?
Most of the TMA is absorbed, very little in feces ?

Not really much connection with TMAU but good to know research is going on about the gut flora and TMA metabolism.

FMO3 DNA testing
Update Aug 17 :
Genos is back with it's EXOME test

Note :
Exome/Genome testing may be better option than single gene testing.

See this post : link

Note : Genos Exome Testing.

Exome testing is almost the same price now as single gene testing. Also Genos is consumer friendly, which standard DNA labs are not.

So the blog offer to test solely for FMO3 is almost obsolete, and so no longer offered.


Does Genos fully sequence FMO3 gene ?

At the moment it is not clear, but hoped this will become clear over the next few months

Note : possible 'wild west' way of testing FMO3
Use an ancestry dna site and rummage through the raw data
