I have a forum The Truth in Medicine, where I have posted on a lot of these topics.  So am providing you links to some of these posts.  Some of the other posters there may also have some suggestions.

 All of them. I suffer from body odor, and I believe it gas something to do with the digestive system.

I display symptoms of IBS, and I am looking into the possibility of leaky gut as a possible cause for the odor.

Probiotics such as kefir and cultured foods, fibers and yucca root and licorice root are recommended for IBS and leaky gut.

I don't mind discussing the issue of anxiety either, as I have always dealt with anxiety, which has worsened considerably due to the body odor.

I am currently trying to find out which medications would actually calm me down. Feel free to contact me if you wish to talk about any of these things.

Body odor can be from a number of reasons such as excess protein intake, liver toxicity,  excess intake of synthetic B vitamins, etc.  A few suggestions to start with include using bitters and natural B vitamin sources to cleanse the liver:

Zinc may also help.  Zinc deficiencies can lead to increased body odor and bad breath.  Recommended dose is 25mg twice daily with meals.
