CORTEX pairs the world’s most studied nootropic stack — caffeine + L-Theanine — with essential B vitamins. Each ingredient has a clear job.
We kept the formula tight on purpose. Every ingredient survived a simple filter: does it have real human research, a known mechanism, and a track record of safety?
The same adenosine-blocking compound found in coffee and tea, delivered in chewable form for faster absorption. Paired with L-Theanine, caffeine + theanine is the most studied nootropic stack in the literature — and the most consistently effective.
An amino acid found naturally in green and black tea. L-Theanine promotes alpha-wave brain activity — the same state associated with relaxed alertness. Research shows it sharpens attention and reaction time while blunting the jittery side effects of caffeine.
A water-soluble vitamin essential for neurotransmitter synthesis — including serotonin, dopamine, and GABA. B6 supports mental energy and mood regulation, and is involved in over 100 enzyme reactions related to brain and metabolic function.
Critical for red blood cell formation, neurological function, and DNA synthesis. B12 supports myelin sheath maintenance — the protective coating around nerve fibers that enables fast, clear signal transmission in the brain.
CORTEX uses three ingredients with decades of peer-reviewed research behind them. We kept the formula simple on purpose — no trendy fillers, no proprietary blends, no label padding. Caffeine + L-Theanine + B vitamins. That's it.
No proprietary blends. No mystery doses. Every ingredient and mechanism is disclosed.
Natural caffeine, L-Theanine, Vitamin B6, and Vitamin B12. No artificial sweeteners, no nicotine, no synthetic stimulants.
Pop one or two pieces whenever you need to focus. Most people notice a shift within 5–10 minutes. Effects last 1–2 hours. Don't exceed 6 pieces in 24 hours.
Sharper, calmer, and more locked in — without the jitters of coffee or the crash of energy drinks. The L-theanine smooths the caffeine into clean, alert focus. No spike. No wall.
CORTEX contains zero nicotine and zero synthetic stimulants. The caffeine dose per piece is roughly half a cup of coffee. It is non-habit-forming when used as directed.
