I haven't noticed any difference really, but I do like my tea better when I have a lot of different stuff in it...for the most part! 😜 I do a lot of fasting and have tested and it doesn't appear that my black tea with kombucha and kefir in it takes me out of a fasted state, so it's a nice little treat in the middle of the afternoon on fasting days. It gives me something to look forward to!
