Oral and body odor is related to gastrointestinal health. Few people have the right balance. This effects how the enitre body functions, actually the digestive system makes up about 80% of the immune system!
First place to start is by incorporting probiotics into your daily regimine. That said, dairy-based probiotics are not the answer. You want a non-dairy probiotic. I have been taking Pet Flora for over 3 years- it is human grade. While it did a lot for me it did not resolve BO, which is likely the result of having been on prednisone for over 20 years. FYI, Dr Clarkes liver cleanses helped considerably!
Still, after some 15 cleanses, ansd 3+ years taking Pet Flora, the BO presisted. I took Sulfur for an entirely differnet reason, but my BO finally went away!
