Why L-Theanine?
Here are four compelling reasons why someone should take SYNRG L-theanine + Magnesium Glycinate
Promotes Mental Clarity & Focus
L-theanine is known for its ability to enhance alpha brain waves, which are associated with a calm yet alert mental state. Unlike caffeine, it delivers focus without the jitters or crash, making it ideal for work, studying, or staying productive throughout the day.
Icon Reduces Stress & Supports Calmtext
L-theanine helps regulate neurotransmitters like GABA, dopamine, and serotonin—chemicals that influence mood, relaxation, and emotional balance. When paired with magnesium glycinate, a highly bioavailable form of magnesium, it helps relieve anxiety and reduces nervous system overactivity.
Improves Sleep Quality Without Drowsiness
While not a sedative, L-theanine encourages deeper, more restorative sleep by calming the mind before bed. Magnesium supports this by relaxing muscles and reducing nighttime cortisol levels. Users wake up feeling refreshed, not groggy.
Naturally Boosts Energy & Mood Stability
With better focus, reduced stress, and more restful sleep, your baseline energy naturally improves. SYNRG’s formula helps you stay balanced and steady through life’s ups and downs—ideal for busy professionals, parents, or anyone managing ADHD or anxiety.

Just what I needed.
As a mother of three, SYNRG’s L-theanine supplement has been a game changer. Since I started taking it, I’ve noticed a huge drop in my stress levels and the brain fog I used to deal with daily has completely cleared. I feel more focused, calm, and mentally balanced throughout the day.

Fast delivery!
I won’t lie, I came across SYNRG L-theanine in an ad and thought, yeah right, no way this works. But a friend of mine (who also struggles with focus and anxiety) had already been taking it—and swore by it. Now we both use it daily. It’s seriously made a difference in my clarity and calm.

Trustpilot reviews
Excellent 4.8 / 5

As a dad with a high-stress job, I finally feel balanced.
I work in corporate finance and have two kids under 6. My brain is constantly racing, and I’ve tried everything from meditation to energy drinks (spoiler: they made it worse). SYNRG’s L-theanine is the first thing that’s helped me feel calm but focused—without feeling sluggish. It’s now part of my daily stack right before my morning Zoom calls.
Bonus: I’ve stopped snapping during rush hour.

Helps me manage anxiety & stay grounded—naturally.
I’ve always dealt with social anxiety, and after reading up on L-theanine, I decided to give SYNRG a shot. I was super impressed by the clean ingredients and transparency. This stuff actually helps! I take it mid-morning and it keeps me centered, even during high-pressure meetings or long travel days.
The magnesium glycinate combo is genius. Highly recommend for anyone who wants a non-synthetic approach to mental wellness.

Night owl turned morning person. Who am I?
As a full-time music producer, my schedule is chaos. Studio sessions at 2am, sleep by 5am—terrible habits. I started taking SYNRG’s L-theanine + magnesium before bed and the change has been wild. I don’t just fall asleep easier—I wake up feeling like my brain actually rested.
No more groggy mornings or racing thoughts at night.
Legit life upgrade.
