Oral probiotics need to dissolve in your mouth to work. Bacteria on your tongue and throat break down proteins into volatile sulfur compounds, the main cause of bad breath. Dysbiosis in your mouth differs from imbalances elsewhere in your body but can show up as related symptoms.

For an oral probiotic, the delivery system needs to be dissolvable in the mouth and then yes, the actual strains of bacteria are different. So microbiomes around the body have different types of bacteria in them and the ones in your mouth and ear, nose and throat are different than the ones throughout the rest of your body. And the bacteria that live in our mouth don't just stay there. They can make their way through the body down to the gut by way of swallowing saliva through the oral mucosa. And so specifically with halitosis, you know, you're talking about bacteria usually that live in the tongue and the throat that break down proteins, they release volatile sulfur compounds. That is usually typically what causes bad breath. Any sort of dysbiosis that's going on in the body, which is again something I learned through my story is going to present itself in symptoms, the symptoms that you mentioned and perhaps different microbial dysbiosis around the body that those symptoms are going to present themselves there first.
