L-Theanine
(from Camellia sinensis)

Main benefits:
Calm. Focus. Biohacking. Stress. Sleep.

Origin and Source:
Naturally found in green tea leaves (Camellia sinensis), L-Theanine is a non-protein amino acid known for promoting calm, focused clarity without sedation. Used in Zen practices for centuries and studied in modern neuroscience for its alpha-wave activation, it is a cornerstone of stress-resilient performance. At NØØT, we use isolated L-Theanine in clinical doses for clean, brain-enhancing calm.

NØØT Classification:

L-Theanine is not an Adaptogen, Nootropic, or Phytogen by strict definition. Instead, it is a Neurofunctional Amino Acid — included in NØØT’s system because of its unique ability to modulate brainwaves, reduce stress, and enhance focus without overstimulation. It supports mental performance in a way no plant or adaptogen can replicate.

Key Benefits and Science

Calm Focus & Alpha-Wave Activation

Shown in EEG studies to increase alpha brainwaves, linked to relaxed alertness, creative flow, and meditative focus.
Commonly used to reduce mental noise and increase focus under pressure — without caffeine or crash.

Stress Resilience & Cortisol Regulation

Supports a calm nervous system by modulating GABA, dopamine, and serotonin, reducing anxiety without sedation.
Often used in high-performance stacks for calm under fire — from boardrooms to burnouts.

Caffeine Synergy & Crash Prevention

When paired with caffeine (from green tea, guarana, or coffee), L-Theanine smooths the spike, reduces jitteriness, and improves attention.
The reason why green tea delivers “clean energy” compared to coffee.

Sleep Quality & Nervous System Repair

While not a sedative, it helps reduce pre-sleep overthinking, making it easier to fall into restorative sleep.
Also used in nighttime blends for those experiencing racing thoughts, tech overload, or post-stress depletion.

Why It’s Good for You

L-Theanine is the neurochemical translator between peace and performance. It helps your brain stay calm without feeling slowed down — and focused without anxiety. Whether you’re presenting, creating, recovering from burnout, or just overstimulated from life, this compound gives you the space to breathe, process, and perform.

Usage

At NØØT, L-Theanine is integrated into blends for focus, resilience, and sleep, often paired with Lion’s Mane, Rhodiola, or Magnesium for synergistic nervous system support. It’s your daily calm clarity — no crash required.
