Early human studies suggest potential benefit of Lactobacillus acidophilus in the improvement of gut barrier function. More high-quality studies are needed to understand this relationship. 

Nonetheless, there has been some literature written on protocols aimed at repairing the damaged intestinal lining, improving digestive enzyme activity, and reducing the load of irritant substances such as drugs, chemicals, and allergens, such as noted in this book, http://books.google.com/books?id=31vPCY3WKTsC&pg=PA16&lpg=PA16&dq...  Before going out and buying these supplements, and spending a lot of money (I don’t recommend that you spend a lot of money), first look for the least expensive solutions.  

One of the recommendations is found on #15, which says, Removal of offending foods or food allergens from the diet.  The problem lies in that you really don’t always know which are the offending foods, choline, meat proteins, dairy products, etc.  

Since I am not a health practitioner, I cannot recommend to you what you should do.  I can only tell you what worked for my son  (see my previous posts in CureZone http://curezone.com/forums/fm.asp?i=1191287#i ). He focused on cleaning out his intestines with 2 medicines his doctor prescribed for him, Enulose (lactulose) syrup (10gm/15ml) 2 tbsp by mouth and a one-time treatment of 7-day treatment of neomycin 500mg tabs (1tab every 8 hours) to finish cleaning the intestines after the initial cleansing with enulose (lactulose).  He repeated the enulose cleansing every 2 to 3 weeks, and now he’s down to every 4 weeks.   

Then after the antibiotic treatment, he ‘rebuilt’ the microbial ecology of the gut with probiotics.  He got probiotics at a local health food store, and made sure it has been refrigerated because many of these organisms die at room temp.  Many people keep them refrigerated even when some products claim it’s not necessary.  He followed the dosage prescribed on the box.  

Remember that you already have toxins in your blood, and that your body is trying to excrete them through your skin (sweat), your lungs (breath), urine, mucous membranes, saliva, and all other body secretions.  So even if you clean out and rebuild your intestines, you need to give your body time to clean out your blood of the toxin saturation it has accumulated through the years.  This process will take months ONLY if you stick to it.  Your odor will decrease slowly but surely.
