L Theanine - The relaxation amino acid†
L Theanine bridges that gap. It supports your body’s natural calming system with clinically backed ingredients like 99% pure Suntheanine® L-Theanine, Glycine, and Glutamine—amino acids that soothe your nervous system without knocking you out.
Modern life doesn’t stop—and neither does your mind. Whether it’s work stress, racing thoughts, or caffeine-induced jitters, staying calm and clear feels harder than it should. But sedating yourself into foggy stillness isn’t the answer either.
Before: You’re wired, anxious, and unfocused.
After: You’re centered, alert, and emotionally balanced.
Whether you’re preparing for a big presentation, winding down before bed, or navigating daily stress, L-T® Complex is your daily mental reset—safe, natural, and fast-acting.
How It Works
Simple Support for a Calmer, Sharper You:
-
Activates Alpha Brain Waves
Suntheanine® L-Theanine promotes a relaxed but alert mental state within 40 minutes. -
Nourishes Calming Neurotransmitters
Glycine and Glutamine support GABA, serotonin, and dopamine for balanced mood and focus. -
Smooths Out Caffeine Jitters
Perfect alongside your coffee to maintain energy without feeling overstimulated.
Why people love it
- Takes the edge off without dulling your spark. Suntheanine® helps your brain slip into the same calm, creative “alpha” rhythm associated with flow states—so you feel present, not sedated.†
- Clean, complementary aminos. Glycine and Glutamine nourish your body’s natural production of calming neurotransmitters, reinforcing steady mood, clear focus, and relaxed muscles.†
- Works fast and plays well with coffee. Many users take it with their morning caffeine to smooth the lift and extend the focus curve.†
When to use it
- Morning: Pair with coffee or tea to keep energy steady and prevent jitters.†
- Midday: Take during high-stress work sprints, travel, or social situations where you want calm confidence.†
- Evening: Use to release the day’s tension and set the tone for restful, natural sleep support.†
What you’ll notice
Within about 40 minutes, most people report a gentle shift: fewer racing thoughts, less “startle,” and a clearer ability to prioritize. You stay alert and productive—just calmer, kinder to yourself, and easier to be around.† Over time, consistent use can help you respond rather than react, making stress feel more manageable.†
Quality you can feel
We use 99% pure Suntheanine®, the premium, patented form of L-Theanine that mirrors the amino acid found naturally in green tea. It’s vegetarian, non-habit forming, and intentionally blended with glycine and glutamine for a rounded, body-and-mind sense of ease. Every batch is third-party tested for purity and potency.
How to take
Follow the label directions. Many people do well with one serving during the day for calm focus, and another in the evening for smooth wind-down. It is suitable for daily use and for “as-needed” moments before presentations, interviews, flights, or crowded events.†
Pairing ideas
- With magnesium at night for deeper relaxation.†
- With B-complex in the morning to support stress resilience.†
- With adaptogenic tea (caffeine-free) for a soothing ritual.†
Who it’s for
Anyone seeking calm clarity—busy professionals, students, parents, creatives, travelers, and caffeine lovers who want the benefits without the buzz.†
Good to know
L-Theanine is generally non-drowsy, but individual responses vary. Avoid combining with alcohol or sedative medications. If pregnant, nursing, on blood pressure medications, or managing a medical condition, consult a healthcare professional before use. Keep out of reach of children.
Feel the difference of relaxed attention—so you can do your best work, be fully present with people you love, and end the day with a quieter mind.†
Eco note: our capsules are dye-free, and our formula contains no gluten, soy, or artificial stimulants—just targeted amino acids designed for purity, consistency, and results. Everyday.
