I started buying Brite drinks when they first launched onto the market a while ago. I run my own business and was struggling with focus and maintaining my usual level of productivity. So when I saw their nootropic drink, specifically formulated to help with focus, I was keen to give it a try. The pineapple/mango combination is luscious: not too sweet, just the right amount of sharpness. Refreshing and tastes high end. I find that a can mid afternoon, just as my post lunch slump hits, is perfect to bring my brain back online and keep me mentally at the top of my game. On the odd occasion that I work through the night and the following day, these drinks keep me more than just awake, like coffee could. I stay feeling switched on and focussed throughout the day. I don’t get a caffeine come down nor does it disrupt my sleep. So I can even drink a can later afternoon or into the evening without disruption my sleep pattern.
