It is not to discourage you... I was wondering if you know that Grapefruit-Seed-Extract kills the friendly bacterias too? If you search you will find the information everywhere on the internet. It is recommended to take probiotics on a different time from Grapefruit-Seed-Extract (for instance: Grapefruit-Seed-Extract in the morning and probiotics before you go to bed), so that you can replenish what the body is loosing. Otherwise, the problem will return and even worse. The problem with bad breath and bo is on the bad bacterias. THey are the stinky ones, thanks God there is GSE. But it is necessary to keep the balance....
