There are capsules which have various probiotics in them. Now that this news has come out, I am sure they will soon have capsules advertising they have this particular one!
K9mbucha is made from half-strength tea, so it usually doesn’t affect one’s teeth as much. And people who make it at home can use green tea, reducing that effect even more.
There are tablets available just not from very reputable brands as far as I can tell. And green tea is great. I drink that every day. Just not at a pH on par with 7up/Mountain Dew/sprite. Still, I suppose I could be worse. It could be Coke or Pepsi that are crazy acidic. :)
