Where should I buy MMS? I am ok with mixing the stuff. Many thanks!

Hi there,
Had a couple questions about the probiotic brews.

1 – Does adding fruit to the brew ( lets say a pineapple ) change the taste of the brew in any way? Or is it just an additional source of sugar for the bacteria?

2 – Can you add Limes and Lemons to the brew? Is the acid in them harmful to the bacteria?

Thanks for the help 🙂
