Your body will tell you. You'll have some pretty nasty die off if you drink too much. I'm having about 4-6 ounces a day right now

my die-off with kefir was pretty insane. i was also taking Amasai and raw mozarella cheese though. i didn't research to much before taking the huge amount that i had taken. boy did i pay the price with some serious fatigue

and disorientation. dEfintely a die-off reaction. it can't be that it's because i'm allergic to cheese. i eat store bought cheese all the time and nothing like that happens.

I've also eaten the kefir from the store bought kind and again nothing happens. Bought when i bought the raw kind from a local farm that really kicked my but and left me in bed because i abused it and took way too much too soon.

Unlike oral probiotics, i don't know how, but you better believe that the kefir does have the potential to reach the gut. Otherwise how would we ever have probiotics/ live cultures in our guts.

I've never had a reaction like the one i had from taking any oral probiotic, other than taking nystatin which was for my yeast infection. Oh, and yes i do have a yeast problem may i add. So i'm assuming this was a die-off reaction.
