Re: rotten egg odor

Yes, Wesley, unfortunately, this is all too common with doctors who have no understanding of systemic causes of body odor.  It probably isn't from one source alone.  The gut can micro-flora imbalance could be one source with an overgrowth of the bad bacteria, and it could also be any metabolic enzyme not working well, etc.  This is all a new field of study that most MDs have no clue about. 

I can see where your doctor woud consider Kefir good in that it is a cultured, enzyme-rich food filled with friendly micro-organisms that help balance your gut ecosystem.  However, it supplies complete protein, which probably contains choline (choline is a type of protein), or any other type of protein your body might not be metabolizing well.  http://www.kefir.net/

I would try probiotics, like Jarro-Dophilus ESPS that you can purchase online, http://www.betterlife.com/prod_home_page.asp?prod_id=27835, which would probably have the essentials found in Kefir wtihout the protein part of it. 

You might want to go to the dermatologist who usually prescribe antibiotics for the acne anyways.  Take the NIH odor management protocol print-out to see if he thinks any of the recommended antibiotics would also help you with your acne.  That way, you can kill 2 birds with one stone.  Print out the info on any of these to show your dermatologist to help validate what you're asking for:  Genetests.org page on Trimethylaminuria
Rarediseases.info.nih.gov: What treatment is available for trimethylaminuria?

You might also want ask your dermatologist which soap to use for acne.  We use Olay Daily Facials Clarity Daily Scrub it's oil free and has Salicylic Acid, which is good for acne treatment if you should have oily skin with acne. http://www.drugstore.com/products/prod.asp?pid=139175&catid=21234, because our dermatologist recommended a soap that contains Salicylic Acid. 

The body soap that I use has sea salts and microbeads and has a good pH balance.  It's Olay Body Daily Purifying Body Wash, http://www.drugstore.com/products/prod.asp?pid=163190&catid=64337.  Sometimes I find these in most drug stores, but I usually just order it online. 

Best of luck to you.
