I drink 1 litre of milk kefir, and 1-2 cups of water kefir a day.
I see no problem with that, but I’m interested in whether or not you’ve experienced any die-off symptoms with that amount.
Regarding die-off. I would have to say no.
I get no brain fog and feel fine.
My die off sypmptoms ended about 1 week after I started my cleanse.
I do get a bit of bloating; but the bloating may or may not be linked to the kefir.
