Answer (estimate, in theory) : about 10-20g DMB a day (divided into doses)
About this answer :
This is an estimate by a very respected CVD expert in a recent overview paper of the TMA-oxide - atherosclerosis connection proposed by Hazen et al in 2011.
Answer is based on Mouse studies for atherosclerosis :
The answer is not based on humans taking DMB as trials have not reached that stage. It is an estimate based on extrapolating the dosage given in mice studies. So you could say it is a 'expert estimate based on mouse studies' given the current info.
The estimate is generally from this overview paper : link
Acronyms
DMB : 3, 3 dimethyl-1-butanol
TMAO : trimethylamine-n-oxide
TMA : trimethylamine
CVD : cardiovascular disease
FMO3 : flavin mono-oxygenase enzyme (isoform 3)
About DMB :DMB : 3, 3 dimethyl-1-butanol
TMAO : trimethylamine-n-oxide
TMA : trimethylamine
CVD : cardiovascular disease
FMO3 : flavin mono-oxygenase enzyme (isoform 3)
DMB in this case refers to 3, 3 dimethyl-1-butanol.
Atherosclerosis and TMA-oxide theory :
Put forward by Hazen et al of Cleveland Clinic in 2011. My impression is that the theory is that TMA-oxide may be the main factor in the development of atherosclerosis.
Connection with TMAU :
Since TMAU is proposed as being a malodor caused by TMA, any research that may block TMA formation in the gut would be a potential therapy. This is an obvious target for the 'atherosclerosis researchers' to aim for. So TMAU patients should be incidental benefactors of this approach.
Where do you humans get TMA from ?
TMA is smelly so is not normally consumed by humans. Nor is it a metabolite from human metabolism. It's only real source in humans is gut flora altering certain compounds in the diet (e.g. choline, carnitine, lecithin, TMA-oxide in fish).
The 'TMA blocker' story so far :
Hazen et al lead research into the TMAO - CVD theory. In Nov 2015 they published a paper showing DMB blocks TMA formation in mice (gut).
How long until a 'TMA blocker' drug is available ?
Cleveland Heartlab have already signed a deal with Proctor & Gamble to market an 'over the counter' TMA-blocker drug. It is not known when this will be available. I am currently presuming it may be DMB based, but perhaps they will find an even better 'TMA-blocker'.
How can you get DMB now ?
DMB is a natural compound in things like balsamic vinegar, olive oil, red wine etc. I do not know how much you would need to take to get 10-20g daily of DMB. My own view is that these foods are probably bad for people with FMO3 issues, as they will likely contain many other FMO3 substrates that may end up causing smells (probably indirectly after being altered by gut flora).
My own view :
I am very optimistic about a 'TMA-blocker'. But my own belief is that people with an FMO3 issue probably smell of all FMO3 substrates and not just TMA. So that concerns me but I am still optimistic. Also FMO3/TMAU was a very neglected disorder, but now TMA metabolism in humans is on the center of radars for atherosclerosis researchers. I will certainly buy DMB when available. If I thought TMA was the only malodor problem I would be ecstatic.
It also shows how TMAU/FMO3 has been a neglected disorder, as this therapy is an obvious concept which was never looked at for TMAU. Now that it is proposed to be connected with CVD we can expect lots of research into TMA metabolism.
My feelings on this (in tags) in relation to metabolic/systemic malodor :
optimistic, excited, cautious, research leads could appear from anywhere now, TMA metabolism is on the radar bigtime.
