How Does It Work?
How Nitro delivers calm unlike anything else
Most calming products rely on ingredients that build calm slowly over time, not in the moment you need it. Nitro ZenPouch works the other way around: tucked under your lip, the pouch releases a fully dosed blend of the best natural calming ingredients into your saliva, steadily, for as long as you keep it in. You feel the cool tingle right away and calm settle in within minutes, and it's the same way kanna has traditionally been taken: chewed and held in the mouth.
L-theanine, 200 mg: The full clinically studied dose of the calming amino acid from green tea leaves, which promotes relaxed, clear focus without making you drowsy.
Zembrin® standardized kanna: Kanna is a South African succulent that the San and Khoikhoi peoples have chewed for centuries to ease stress and lift their mood, long before Dutch explorers first wrote about it in the 1600s. Zembrin® is its standardized, clinically studied form, so every pouch carries the same amount of kanna's active compounds, unlike raw kanna, which varies wildly from plant to plant.
Magnesium bisglycinate: A gentle, well-absorbed form of magnesium, the calming mineral your nervous system relies on, to round out the formula.
Lavender oil: We chose lavender because, out of all the aromas in the world, it's the one most known to deliver calm. Its soft scent arrives with the cool mint the moment the pouch goes in, an instant cue that calm is on the way.
Together, they release steadily into your saliva for as long as you wear it, so you feel a shift in minutes, not the weeks slow-building supplements ask for.

Meet L-Theanine:The Calm-Focus Amino Acid
L-theanine is a naturally occurring amino acid your brain uses to support a relaxed, alert state, often described as calm focus. It works with your nervous system's own settling signals, without acting as a sedative.
Stress Spikes, Focus Slips
Deadlines, big calls and racing thoughts flood your nervous system with tension signals faster than your body can settle them, leaving you wound up right when you need a clear, steady head. This is where people often reach for something unhealthy.
The Calm-Focus Effect
ZenPouch breaks the habit with a clinically studied dose of L-theanine delivered quickly with a small satisfying tingle under the lip. Paired with Kanna, a South African succulent that the San and Khoikhoi peoples have chewed for centuries to ease stress and lift their mood, it quickly promotes a clear-headed state so you can stay calm yet focused under pressure.
Delivered Under Your Lip
Most calm pouches use a token 35 to 100 mg dose. Nitro ZenPouches carry the full clinically studied 200 mg of L-theanine, released steadily through your saliva while it sits under your upper lip. With the help of the cool lavender-mint aroma, within a few minutes you feel the calming as actives keep releasing over the full wear time.

Formulated to Act Fast.Providing a Calm, Clearer Focus.
When the full studied dose of L-theanine meets real-world use, the results speak for themselves.
4 Studied Actives For Relaxed, Clear Focus in Minutes
Every pouch delivers full, transparent doses of each carefully selected natural active, no proprietary blends, no guessing.
L-Theanine
Clinically studied 200 mg that acts fast. The calming amino acid from tea leaves. At this dose, studies show it starts easing tension rapidly, supporting a relaxed clear focus with no drowsiness.
Zembrin® Kanna (Sceletium tortuosum)
The plant South Africa’s first peoples held in the mouth for calm. For centuries, San and Khoikhoi people chewed fermented kanna and kept it tucked in the cheek to take the edge off and lift their mood. Zembrin is its patented, standardized & perfected extract, so every pouch delivers the same steady calm.
Magnesium Bisglycinate
The gentle form of the mineral your nerves run on. Magnesium supports normal nervous-system function, yet nearly half of adults fall short. Bound to glycine, this form is well absorbed and easy on the stomach, a steady mineral top-up beneath the calm.
Lavender Oil (Lavandula angustifolia)
The most-studied calming scent in the world. Dozens of controlled trials link lavender’s aroma to feeling calmer. Its soft scent rises with the cool mint as soon as the pouch goes in.

keeps me level through the rush
Slammed lunch into dinner overlap, tickets stacking up, and my head used to be racing the whole shift. These keep me steady and clear instead of wound up, no fog either. Only gripe is the can price feels steep next to what I used to grab at the store, but the focus is worth it.

mostly good, one complaint
I started using these about a month ago after a coworker mentioned them. I open the can and tuck one under my upper lip, leave it for twenty to forty minutes, and I do feel something shift within the first ten minutes or so. My baseline mood does feel steadier day to day now, less of that background tension I used to carry around the office. My only real complaint is maybe the lavender, not the biggest fan but it does apparently add to the effect so I guess I can live with it

Reason 4
Same Ritual, Zero Nicotine
Tuck it under your lip just like a nicotine pouch, minus the nicotine, the dependency and the gum irritation you're trying to get away from.
