I know this thread is old, but i'm new to the forum and am hoping it will encourage a new conversation about sugar free red bull as I am looking for an alternative to coffee for those times when i need a quick energy boost.
It is true that coffee will raise your blood sugar. The caffeine hit makes your body release adrenaline, like the fight or flight reaction. in turn, this tells your liver to release extra glucose in the anticipation of needing to make a quick escape. Therefore the stronger your coffee the more your BG will rise. And i like strong espresso...
So, with that in mind, can any one add any experiences of using either sugar free red bull, or anything else for that matter, for a quick boost which does not have a significant impact on blood sugars? (btw class A is not the answer :***: )
