L-Theanine (as Suntheanine)

L-Theanine is an amino acid naturally found in tea leaves, best known for its ability to promote a sense of calm without making you drowsy. Suntheanine® is a patented, pure form of L-Theanine made through a fermentation process that mimics how it’s created in nature. This ingredient supports relaxation, mental focus, and a balanced stress response by increasing calming brain chemicals like GABA and serotonin, as well as encouraging alpha brain waves, which are linked to a state of “relaxed alertness."*

Suggested Use: As a dietary supplement, take one (1) veggie capsule daily with 8-12 fl oz of water, preferably with a meal.

Stress & anxiety: promotes relaxation by increasing calming brain waves (alpha waves) and reducing overactive stress responses, without causing drowsiness.*

Sleep problems / mild insomnia: helps quiet racing thoughts and supports deeper, more restorative sleep cycles.*

Difficulty focusing: enhances alertness and mental clarity, making it easier to concentrate on tasks for longer periods.*

Caffeine jitters & overstimulation: smooths out the side effects of coffee or energy drinks while preserving the boost in alertness.*

Low mood & irritability: supports healthy serotonin and dopamine activity, which can improve mood stability and overall emotional well-being.*

Stress-related blood pressure spikes: research suggests L-theanine may help maintain normal blood pressure in stressful situations.*

Cognitive performance & memory: by promoting calm but alert brain activity, Suntheanine may improve learning efficiency and recall.*

Tension headaches or muscle tightness: L-Theanine’s relaxation effects can sometimes ease stress-related physical tension.*

GABA (gamma-aminobutyric acid) is a calming neurotransmitter that helps keep the brain from becoming overstimulated. When GABA levels are too low, people may experience symptoms such as:

- Anxiety or nervousness
- Racing thoughts
- Trouble falling or staying asleep
- Feeling “on edge” or irritable
- Muscle tension
- Difficulty relaxing

If these symptoms are ongoing, it’s always best to talk to a healthcare provider to rule out other possible causes and discuss support options.*

Revive Suntheanine is meant to be taken orally with water, preferably with a meal. Just take one (1) veggie capsule per day as suggested on our label. For best results, take it consistently each day.

In the morning or afternoon, it may help with focus, calm, and stress support.

In the evening, it can promote relaxation and better sleep if taken 30–60 minutes before bed.
Always follow the directions on the label or consult with your doctor for more personalized guidance.*

- Are pregnant or nursing
- Are under 18 years old
- Take prescription medications for blood pressure, sleep, or mood (as L-theanine can interact with some of these)
- Have a diagnosed medical condition and are unsure if L-theanine is safe for you

When in doubt, check with your doctor or pharmacist before starting any new supplement.
