You don't need more caffeine.
You need better caffeine.
The three things people tell us they were trying to escape — in their own words.
Wired, not focused.
More caffeine just turns up the noise. Klar pairs its caffeine with L-theanine for energy that feels quieter.
“I usually get jitters from caffeine because I'm so sensitive to it which makes me stay away.”Saliho T. · Verified buyer
The 2pm cliff.
A big spike followed by a wall. Customers describe Klar's lift as smooth and steady instead.
“A smooth boost in my afternoon/evening at work with no discernible peak or trailing off of the effect.”Ethan G. · Verified buyer
Energy, minus the junk.
Zero sugar. Vegan, keto, gluten-free and non-GMO.
“Klar has weaned me off all the other junky energy drinks I used to be addicted to.”Christine M. · Verified buyer

Top 3 in Erewhon’s cognitive category. Also on the shelf at Zupan’s.
Caffeine,
with a co-pilot.
L-theanine is the reason Klar feels different from a can or a third coffee. Then we added the stuff caffeine alone skips: hydration and B-vitamins.
≈ 1.5 cups of coffee
Klar Focus Stack
Nootropics and adaptogens: natural caffeine from green tea (150mg), L-theanine, taurine, L-citrulline, Alpha-GPC, Panax ginseng, L-tyrosine.
Klar Hydration Blend
Himalayan pink salt, sea salt, potassium chloride. 200mg sodium (9% DV).
B1 · B3
B-vitamins

Amounts as listed in the Supplement Facts on klarlabs.co. Confirm against the current printed label before launch.
Same caffeine.
Completely different curve.
L-theanine, paired 1:1 with 150mg of natural caffeine from green tea, is built for focus that feels steady.
Illustrative curve. Not based on clinical data.
Tear. Pour.
Shake. Go.
No can, no cold brew, no line. It lives in your bag, your car or your gym kit.
Tear a stick
One stick = one serving. A 28-pack is one a day for four weeks.
Pour into water
Bottle, glass or shaker.
Shake for 10 seconds
Then get on with your day.
Four flavors. Zero sugar.
Every flavor has the same formula. Pick the one you'll look forward to.
Klar vs. your usual.
We kept this honest. Black coffee has no sugar either. It just doesn't do the rest.

“Varies” = depends on brand. Klar price per stick based on the 56-pack with Subscribe & Save ($61.60 / 56).
Don't take
our word for it.
“I've found THE product that allows me to stay truly focused without a caffeine crash, without sacrificing flavor, or weird additives in the ingredient stack.”
“Klar tastes great and I didn't get the jitters like I do with most energy drinks. I started substituting my morning cup of coffee with Klar.”
“I am a little sensitive to caffeine (at least in typical energy drinks) but I haven't seemed to have any negative side effects with Klar.”
“Couldn't believe how easy it was to mix these… Love the clarity and boost it brought as well. Will be reordering!”
“Have been mixing it with water every morning and completely stopped drinking coffee as a result.”
