I make my own kombucha as well as purchase some from Whole Foods. Its pretty good stuff but not to consume in excess. If I drink too much then I get a headache because of the detoxifying properties. I recommend consuming a small amount each day. If you need any information on how to brew it feel free to ask me I have a jar of cultures as well as pictures of the progress.
ALSO from personal experience if you have a BO problem it may amplify it or you will smell like Kombucha for a bit (like a vinegary smell) since the tea is such a strong powerful detoxer
