It is great! It is a nice relaxing boost! However if you are a regular coffee drinker you may not feel the effects, if you are consuming this daily multiple times I think the effect wears off and your body just gets accustomed to it. I think this should be drank as a "pick-me-up" to aid in boosting your mental clarity n mood. I feel products like these need to be respected and not just rely on it solely. A healthy balanced lifestyle with these is good. Its all down to the individuals body. See what works for you. 10/10
