The King of Kombucha

Whoa whoa let's slow down here. Kombucha is tasty (IMO) and the probiotics are great -- I enjoy kombucha and kefir regularly. But I'm not going to tell anyone it's magical or guaranteed to not cause them harm. There's simply not enough research either way. Correlation does not imply causation.

  In April 1995, two women who had been drinking the tea daily for 
  2 months were hospitalized with severe acidosis -- an abnormal 
  increase of acid levels in body fluids. Both had high levels of 
  lactic acid upon hospitalization. One woman died of cardiac 
  arrest 2 days after admission

I think that it's more likely those two women had underlying health issues they were trying to cure with kombucha instead of getting proper treatment; I find it plausible that it can cause harm to some people with preexisting conditions we have not yet identified.

You can die from drinking too much water too, you know...

Kombucha is not a brand
