You're not alone. More than 1 in 3 coffee drinkers experience jitters, anxiety, and crashes—but keep drinking anyway because they love the ritual and need the energy.

The problem isn't you. It's how caffeine hits your nervous system.

Coffee triggers a "fight or flight" response—spiking adrenaline and cortisol.

That's why your heart races, your hands shake, and your brain spirals into
overthinking mode.

But here's what most people don't know:

There's a natural amino acid called L-Theanine (found in green tea) that
neutralizes caffeine's anxiety-inducing effects WITHOUT reducing the energy boost.

When you pair coffee with L-Theanine, you get:

✓ Calm, steady focus—not jittery chaos
✓ Smooth energy for 4-6 hours—no crash
✓ Your beloved coffee ritual—without the anxiety tax

That's exactly why we created Thynk™.

One capsule with your morning coffee. That's it.

No giving up your pour-over. No switching to matcha. No white-knuckling through anxiety just to stay productive.

Just coffee—the way it's supposed to feel.

Try Thynk™ risk-free for 90 days. If you don't feel noticeably calmer and more
focused, we'll refund every penny.

I've tried other L-Theanine supplements and they didn't work. What makes Thynk different?

-----------------------------------------

We're not surprised you've had a bad experience. Most L-Theanine products are under-dosed garbage. Here's what makes Thynk different: 

✓ 200mg of pure, fermented L- Theanine (the clinically-studied dose that actually works—not the wimpy 50-100mg most brands use) 

✓ We add magnesium glycinate to support your nervous system (most brands skip this)

✓ Plus B6 to help your body actually absorb and use the L-Theanine

Thynk is not just another supplement bottle—we're formulated specifically for coffee lovers who refuse to give up their ritual. 

-----------------------------------------

Will this make my coffee less effective? I NEED the energy.

-----------------------------------------

Nope. L-Theanine doesn't block caffeine—it smooths it out. You still get 100% of coffee's alertness, focus, and dopamine boost. What changes? Your nervous system doesn't freak out anymore. Think of it like this:

❌ Coffee alone = Gas pedal floored, no brakes (jittery chaos)

✅ Coffee + Thynk = Gas pedal floored WITH smooth steering (calm focus)

You're not losing energy. You're upgrading how that energy feels. Instead of scattered, anxious productivity, you get steady, locked-in deep work. One software engineer put it perfectly: "I still feel the caffeine kick. I just don't feel like my heart is trying to escape my chest anymore."

-----------------------------------------

How quickly will I feel the effects?

-----------------------------------------

Most people notice a difference within 10-30 minutes. Here's the timeline: 

☕ FIRST 10-45 MINUTES: Instead of the jittery spike, you'll feel smooth, steady energy. No racing heart. No shaky hands. Just calm focus. 

📅 BY DAY 3-5: The effects become even more noticeable. You'll be calmer in high-stress moments— Zoom calls, presentations, tight deadlines. 

🚀 AFTER 2 WEEKS: This becomes your new baseline. Coffee just works better now.

The transformation isn't gradual. You'll feel it on day one.

-----------------------------------------

Can I take this if I drink 3+ cups of coffee per day?

-----------------------------------------

Absolutely. Heavy coffee drinkers usually notice the BIGGEST difference. Here's how most people use it: 

☕ Light Drinkers (1-2 cups/day): One capsule (200mg) with your first cup. That usually covers the entire day. 

☕☕☕ Heavy Drinkers (3+ cups/day): One capsule with your first cup, another with your afternoon coffee if needed. Some of our customers take 400-600mg daily with zero issues. 

Whether you're a "one cup to survive" person or a "cold brew IV drip" person, Thynk works with your routine.

-----------------------------------------

I'm sensitive to supplements. Is this safe for me?

-----------------------------------------

L-Theanine is one of the safest supplements out there. It's literally just an amino acid found in green tea. If you've had matcha, you've already consumed L-Theanine. The safety profile: 

✓ Non-drowsy (won't make you sleepy) ✓ Non-addictive (no dependency or withdrawal)

✓ No tolerance build-up (works the same on day 1 and day 365) Clinical studies have used doses up to 600mg daily with ZERO adverse effects.

The only exceptions:

If you're on blood pressure medication or pregnant/nursing, check with your doctor first. 

If your body can handle green tea, it can handle Thynk.

-----------------------------------------

Will this make me drowsy? I rely on coffee's kick.

-----------------------------------------

Not at all. L-Theanine promotes relaxation WITHOUT sedation. Here's the difference:

🛌 SEDATION = Drowsy, foggy, sleepy (like Benadryl)

☀️ RELAXATION = Calm, clear, focused (like meditation)

L-Theanine creates "wakeful relaxation"—the same relaxed-but-alert state Buddhist monks achieve during meditation (why they've been drinking L-Theanine-rich tea during study sessions for centuries). You'll feel mentally sharp, physically calm, and emotionally steady—but NOT sleepy. Think of it like this: L-Theanine removes the distraction of jitters and anxiety, so caffeine can actually do its job properly. 

-----------------------------------------

What if I forget to take it one day?

-----------------------------------------

No problem. You'll just experience your normal coffee jitters again. That's it. No withdrawal. No dependency. No "I NEED this to function" situation.

L-Theanine isn't habit-forming. It's more like adding cream to your coffee—nice to have, makes the experience better, but if you forget? Life goes on.

-----------------------------------------

How does Thynk calm anxiety without making me tired?

-----------------------------------------

Here's the science in plain English: 

THE PROBLEM: Caffeine blocks adenosine receptors, triggering adrenaline and noradrenaline—your "fight or flight" hormones. That's why your heart pounds and your brain goes into overdrive. 

THE SOLUTION: L-Theanine promotes alpha brain waves (relaxed-but-alert state) and boosts GABA (a calming neurotransmitter). It tells your nervous system: "We're safe. No need to panic." When combined with caffeine, L-Theanine: 

✓ Smooths out the adrenaline spike (no racing heart) 

✓ Reduces anxiety and mental clutter (no overthinking spirals)

✓ Enhances focus without jittery overstimulation The result? Clean, sustained energy for 4-6 hours. 

No jitters. No crash. Just smooth, steady productivity. It's like upgrading from a janky rollercoaster to a smooth, fast train. Same destination, way better ride.

-----------------------------------------

What's the right dose? How do I take it?

-----------------------------------------

Super simple:

🥤 RECOMMENDED DOSE: 

Take 1 capsule (200mg) with your first cup of coffee. That's it. This covers most people for the entire day, even with multiple cups later. 

⚖️ THE 2:1 RATIO:

- Average coffee = ~100mg caffeine - Thynk capsule = 200mg L-Theanine - Perfect pairing = smooth energy Extra sensitive to caffeine? Take 2 capsules. Totally safe. 

⏰ TIMING:

Take it at the same time as your coffee—or right before. They kick in together within 30-45 minutes. 

💊 HOW: - Swallow the capsule with your coffee or water - that’s it. No complicated timing. 

Try Thynk-Free fro 90 days. If you’re not 100% satisfied- we’ll refund you. Every penny. 

Coffee tastes better without jitters. Try Thynk™.

"I Thought I'd Have To Choose Between Coffee and Calm. Turns Out, I Can Have Both."

"I was surprised how well it works! I drink coffee every morning for work and this really helped me with my social anxiety. It still has the same wake-up effect but you don't feel jittery and overstimulated. Instead you feel normal and relaxed. It's great I recommend trying it!!

What Our Customers Say

4.8 / 5
Feel more confident
"I've had anxiety for years, and coffee always made it worse. But I love coffee too much to quit. After 3 days of taking Thynk with my morning pour-over, I started noticing I was less awkward in Zoom meetings. I wasn't constantly aware of my racing heart anymore. It stops caffeine from giving you anxiety.
Joslyn K.
Best One So Far
"I've tried multiple L-Theanine supplements and this is the best one I found so far. Most of the them completely kill the energy boost of caffeine but this one doesn't. It's not as strong as caffeine by itself (like 80% as strong) but it's worth the tradeoff if jitters kill your focus.
Eric T.
More Productive
"I use this every morning when I need deep focus. One capsule with my coffee, and I'm locked in for hours. No more jumping between tasks pretending I'm working. It's the difference between feeling busy and actually finishing things."
Jeremy L.
Helps with jitters too
Everyone talks about how much it helps with anxiety but it also helps get rid of jitters. I usually get shaky hands and jitters when I drink caffeine and it makes me feel nervous and worried if my body can handle it and this really helped get rid of the jitters and make me feel normal and give me peace of mind.
Emily R.
Helped my overthinking
This has honestly helped my social anxiety more than anything else I’ve tried. I used to overanalyze every conversation for hours afterward. Now my brain feels quieter — like I can just exist without worrying what everyone’s thinking.
John M.
Big Difference
I didn’t realize how much my coffee was spiking my anxiety and controlling my life. I actually look forward to talking to people now. I feel more confident, less tense, and just more present. It’s a small change that’s made a huge difference in my day-to-day life.
Kayla R.
Works super fast
I was expecting a slow burn type of product, but it started helping me in less than 5 minutes. After drinking my coffee I didn’t get anxiety, I just felt calm and awake. It’s not a hype energy boost; it’s more like your thoughts stop racing and you can finally focus.
Romeo S.
Confidence Boost
I didn’t buy this for confidence, I bought it for focus. But honestly, being calmer made me feel more confident naturally. I don’t panic about saying the wrong thing anymore. I feel like myself again.
Eduardo M.
More Social
This might sound silly, but anxiety from caffeine can really control your life and Thynk really helped me notice that. I’m not as overwhelmed by social stuff anymore. I actually look forward to going out now — and I haven’t done that in years.
Faith O.
Don't quit coffee
I was thinking of quitting coffee because of how bad my anxiety was getting, but I'm really glad I found this! I love getting starbucks and I really didn't want to quit so this was a life-saver!
Riley B.

Questions? We've Got You Covered

Thynkuses L-Theanine to help calm your nervous system and prevent the flight or flight response that is triggered after you drink caffeine. This prevents anxiety normally caused by caffeine, while still keeping the energy boost and “wake-up” effect. Instead of your coffee spiking your anxiety and killing your confidence, you’ll feel calm, awake and ready to focus.

L-Theanine is a natural amino acid found in green tea leaves that helps calm your nervous system without killing the energy-boost from caffeine. Normally, caffeine triggers your body’s fight-or-flight response — raising your heart rate, tightening your chest, and putting your brain in alert mode. L-Theanine helps prevent that by increasing alpha brain activity and boosting calming neurotransmitters, so you still get the energy and focus from caffeine — but without the anxiety, jitters, or crash. L-Theanine is also commonly found in matcha which is why many people report matcha as more calming and less anxiety-inducing than caffeine!

Yes! You’ll still get the same “wake up” effect and mental alertness from your caffeine — you just won’t feel as anxious or overstimulated. In fact, 57% of users described Thynkas “longer-lasting” and “calmer” than consuming caffeine alone. 

Take Thynkimmediately after consuming caffeine. (Coffee, Energy Drinks, Pre-Workout etc,). If you drink caffeine later in the day, you can take a second serving in the afternoon to stay calm and focused without interfering with your sleep.

Absolutely! Thynkis made with naturally sourced, clean ingredients you can feel good about putting in your body. Our hero ingredient, L-Theanine, comes straight from green tea leaves and works gently with your body to calm your nervous system. The formula is free from artificial colors, synthetic fillers, or unnecessary additives — just a simple, science-backed blend designed to prevent caffeine from spiking your anxiety and making you feel overstimulated. It’s safe, gentle, and perfect for anyone who cares about what they put in their body.
