Dopamine and norepinephrine are neurotransmitters involved in attention, motivation and mental alertness. When these signalling pathways work efficiently, it's easier to stay focused and mentally engaged. When they're disrupted, they can contribute to reduced focus, mental fatigue and brain fog. Caffeine from matcha helps increase alertness by supporting dopamine and norepinephrine signalling, while L-theanine helps balance this effect by promoting calm focus. Together, they provide sustained mental performance without the sharp peaks and crashes often associated with caffeine alone.
