from Camellia sinensis (green tea)
An amino acid that smooths caffeine's edge. Calm focus, no jitter spike.
Sourced from green tea
Steady alertness without the sugar-drink crash. Absorbs on your tongue, so no wait.
Methylcobalamin (active form)
Helps your body turn food into energy. The active methyl form skips a step your gut usually has to do.
Doses per strip are being finalized for the label. Every link opens a peer-reviewed source.
Energy Oral Strips are designed specifically for people on the go. When used before exercising or in high-energy activities, they provide noticeable long-term benefits such as improved focus, physical endurance, and mental clarity. They offer increased sustained energy compared to sugary drinks or coffee without the crash or jitters that come with regular caffeine intake.*
The combination of Green Tea Caffeine and L-Theanine work together synergistically to provide sustained energy levels lasting up to several hours. In addition, Vitamin B12 has been added as it helps you stay energized physically and mentally with its essential role in converting carbohydrates into glucose — the fuel your body needs for energy. Furthermore, our strips are carefully embedded with nutrients that can be absorbed directly into your mouth, skipping digestion time in your stomach. This natural combination of caffeine and amino acids immediately boost alertness.*
Why Energy Strips beat your fourth cup of coffee.
Cheaper than the pre-workout you'd waste on a Tuesday. $29.99 tin / 30 strips = about $1/day.
You didn't come here by accident.
You've built your whole day around not crashing at 3 PM. Coffee at 6:15. Second cup at 8:30. A Celsius in the car by 11. You've stopped counting because the number is embarrassing, and you've decided this is just what your adult life is now. You don't fully believe that, or you wouldn't be reading this.
Here's what I think is happening.
Oral caffeine — coffee, Celsius, 5-hour Energy, all of it — peaks in your bloodstream around 45 minutes and falls off on the same slow curve. That slow rise is the jitter. That slow fall is the crash. Your 10 AM cup is peaking at 10:45 and dropping through 2 PM, which is why 3 PM is your wall. It's the shape of the curve.
On top of that, your adenosine receptors — the ones caffeine binds to — adapt to whatever dose you already drink. That's why the cup that used to buy you four hours now buys you ninety minutes. It's not you. It's tolerance biology.
Here's what I made for that.
Energy is a sublingual film — green-tea caffeine paired with L-theanine, the amino acid from tea, in the peer-reviewed pairing that increases alpha brain-wave activity and smooths the jitter without killing the focus. Plus methylcobalamin — the coenzyme-active form of B12 your body uses without a conversion step, absorbed sublingually far more efficiently than the cyanocobalamin in a drugstore gummy.
It dissolves under your tongue in about 30 seconds — onset in roughly 15 minutes instead of 45. Cleaner peak. Smoother tail.
It's not another cup. It's a cleaner one.

How Energy Strips compare to what you're doing now.
When coffee still wins: When you want the ritual. The heat. The 20 minutes with a mug in your hand before the day starts. The strip won't replace that — nothing will. It's for the second, third, and fourth times you'd have reached for caffeine that day.
Will I crash?
L-Theanine pairs with caffeine for calm focus — no spike-and-crash. The energy tapers gently. If you're the person who crashes hard off Celsius, this is the format built for you. But if you're caffeine-sensitive, start with half a strip your first day.
Is the caffeine enough?
The dose lands in the clinically studied range for the L-Theanine + Caffeine pair — enough to give you a clear lift, not so much that you feel wired. If you're used to a triple-shot americano, this won't replace it. It's cleaner, not stronger.
I've been burned by pre-workouts and energy drinks before.
Same. Most pre-workouts are half fillers, half proprietary blends, and stack you at 300mg of caffeine with beta-alanine tingles you didn't sign up for. This is caffeine + L-Theanine + B12. Nothing else stimulant. If it doesn't work for you, email me and I'll make it right.
Do XYNE strips bypass the stomach?
Yes. Energy Strips dissolve under the tongue and the actives absorb through the mucosal tissue directly into the bloodstream — bypassing stomach acid and first-pass liver metabolism. That's why the onset is roughly 15 minutes instead of the 45-minute curve you get from swallowing a pill, coffee, or an energy drink.
How fast does an Energy Strip dissolve?
About 30 seconds under the tongue. No water needed. No aftertaste to nurse. Place it, let it melt, go.
How much caffeine is in it?
The caffeine is green-tea sourced (no synthetic) and paired with L-Theanine in the clinically studied ratio for calm focus. Keep total daily caffeine intake from all sources under 400mg per day (FDA general guidance for healthy adults). If you're already drinking coffee, count the strip toward that total.
Will I crash?
L-Theanine smooths the caffeine curve — the taper is gentle, not the cliff you get from an energy shot. Individual metabolism varies, so if you're caffeine-sensitive, start with half a strip.
Can I take it with coffee?
Yes — but check your daily total against the 400mg FDA cap. The strip is cleaner (no sugar, no synthetic caffeine, no artificial flavors) than most energy drinks, so a lot of customers swap their second or third cup for a strip rather than stacking on top.
Are Energy Strips safe during pregnancy or with medications?
Caffeine is restricted during pregnancy. If you're pregnant, nursing, on medication (especially stimulants, blood pressure meds, or SSRIs), or have a health condition — talk to your doctor before using any caffeinated supplement, including ours. *These statements have not been evaluated by the Food and Drug Administration.

If you're researching at 1am, we're with you. Here are the questions we get most about Energy Strips.
Each strip has caffeine from green tea, paired 1:1 with L-Theanine — an amino acid that eases the jitters. See the safety panel above for exact mg. Keep your total daily caffeine under 400mg (FDA's healthy-adult limit).
Absorption starts on contact and hits full effect in about 30 seconds. Coffee and pre-workout powder take 30–60 minutes through your stomach. The strip is a lot faster.
L-Theanine pairs with caffeine for calm focus — no spike-and-crash. The energy tapers off gently. It doesn't crash.
Yes. Take a strip 5–10 minutes before warm-up. By the time you start, the active ingredients are already in your blood.
Yes. The strip absorbs on your tongue, so food in your stomach doesn't matter. Just know that caffeine on an empty stomach hits faster — start with one strip before stacking.
Use common sense. Add up your daily caffeine (coffee, tea, energy drinks, strip). Stay under 400mg. If you're caffeine-sensitive, drop your other sources on strip days.
Cranberry — light, real flavor, sweetened with stevia and erythritol. No added sugar.
Yes — vegan-friendly, gluten-free, lactose-free, halal, non-GMO, and made without fillers. The strip base is pullulan, a plant-based fiber.
Caffeine is restricted during pregnancy. If you're pregnant, nursing, on medication (especially stimulants, blood pressure meds, or SSRIs), or have a health condition — talk to your doctor before using any caffeinated supplement, including ours.
