Trying antibiotics for fecal body odor

I have had 'intermittent fecal body door' for a number of years. Recently I have decided to try the 'antibiotic route' to see how it goes. So far, having tried 3 antibiotics, I do not seem to be any further along. A main concern is that candida may be a (main) factor. As a reminder though, I must point out that I think it is a FMO3 genetic enzyme deficiency at the root of the problem, but I do think gut dysbiosis is also a factor.

For the record, here is what I have tried and my impression of the result
Antibiotic Dosage Comment
Flagyl 400mg twice daily for 2 weeks Difficult to take. Metallic taste, nightmares etc.. No obvious improvement. Conclude it is too harsh
Amoxycillin 500mg Not as bad reaction as flagyl but still quite difficult, and no obvious improvement
Doxycycline 100mg 1 a day for 14 days Easiest to tolerate but still quite difficult. Did not feel any improvement

Summary : The above antibiotics did not seem to improve my odor or gut dysbiosis and were quite difficult to tolerate, which I suspect is due to being unable to metabolize the drugs efficiently.

I am going to try a few more. Like rifaximin and neomycin

Gut dysbiosis :
This is due to microbes causing a pathogenic environment in the gut. It could be bacteria, fungus, or parasites. It can be in the stomach, small intestine, or colon. Currently orthodox medicine would only think bacteria is the problem, but I don't agree.

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
