Caffeine is the most studied cognitive enhancer on the planet. At the right dose it improves alertness, reaction time, and focus without overstimulating your nervous system.

It works by blocking adenosine receptors — the receptors responsible for making you feel tired. The result is clearer thinking and steady energy, not a spike that burns out an hour later.

The difference between CORE and an energy drink is the dose. Energy drinks overload you with 150-200mg at once. CORE keeps it clean and precise so you get the benefit without the crash.

L-Theanine is an amino acid found naturally in green tea. On its own it promotes calm relaxation without making you sleepy. You feel relaxed but alert.

Combined with caffeine — which is exactly how CORE uses it — it creates what researchers call a synergistic effect. The anxiety and jitters from caffeine disappear. The focus stays.

This stack is one of the most well-documented nootropic combinations in cognitive science. It is the reason CORE feels different from a cup of coffee.

Electrolytes are responsible for transmitting electrical signals between neurons. When your levels drop — even slightly — cognitive performance suffers.

Research shows that even mild dehydration of just 1-2% body weight causes measurable drops in memory, attention, and processing speed. CORE includes a precise electrolyte blend to keep you running at full capacity throughout your focus session.
