Small study : popular probiotic does not decrease TMAO levels

Yakult is a popular Japanese probiotic drink that mainly contains 'shirota' probiotic. Since a 2011 hypothesis put forward that TMAO may be a biomarker of CVD, there has since been much interest in TMAO generation in humans and ways to reduce it. In this small study, Austrian researchers tested what effect taking 'shirota' strain probiotic may have on TMAO levels on a group who have 'metabolic syndrome'. It seems it had no effect.

Metabolic syndrome 
My understanding is that this syndrome is a number of factors that can tend to cause cardiovascular disease (CVD).

What's this to do with Systemic Body Odor ?
My own current view is that most cases of 'systemic body odor' are due to FMO3 substrates. One of these substrates is trimethylamine (TMA). So any research to do with TMA metabolism is of interest to me. Since 2011 a hypothesis was put forward that TMA-oxide may be a biomarker of CVD. This has led to much more interest into TMA/TMAO/FMO3 as before that they were largely ignored by researchers.

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
