While we can’t make any guarantees because everyone reacts differently to ingredients, we can tell you this: MIND FK does not use regular caffeine, but instead, Enfinity Paraxanthine, which is a patented and clinically studied ingredient that isolates all of the good aspects of caffeine and kicks the bad aspects of caffeine that can lead to feeling anxious, jittery, and in a bad mood to the curb. Enfinity Paraxanthine can support enhanced mental focus, clarity, clean energy, reaction time, mood, and an overall sense of well-being.
