Caffeine works by blocking adenosine receptors in the brain, the neurotransmitter responsible for promoting relaxation and sleep. By inhibiting adenosine, caffeine increases neuronal activity and triggers the release of dopamine and norepinephrine, improving focus and reducing fatigue. Each 200mg dose is carefully measured to provide a noticeable boost while minimising overstimulation. Studies show caffeine can also improve reaction time and concentration, making it a favourite amongst students, professionals, and athletes.\u003c\/p\u003e\u003cp\u003eThis product contains caffeine which contributes to increased alertness and improved concentration.\u003c\/p\u003e\u003ch2\u003eHow to Uses \u0026amp; Dosage Recommendations\u003c\/h2\u003e\u003cp\u003eFor optimal effect, take one tablet with water 30 to 60 minutes before you need to feel more awake.
