The Science
How SHIMA Works.
No magic, no mystery — just thoughtful ingredients working together for a smooth, balanced experience without the drawbacks of conventional energy drinks.
The Core Difference
Closer to water than
a chemical cocktail.
Most energy drinks are built around a handful of stimulants — primarily caffeine and sugar — that force a short burst of energy and then leave you worse off than before. SHIMA is fundamentally different. With only 10–15 calories, zero sugar, zero caffeine, and a short, honest ingredient list, it is one of the lowest-impact beverages in the energy category.
Think of it this way: a 12oz SHIMA has fewer calories than most flavored sparkling waters and none of the stimulants in a standard energy drink. The energy-like experience comes from kratom extract and L-Theanine working together — two ingredients with a long history and a well-understood profile.
The Experience
What happens when you drink SHIMA.
A clean, refreshing first sip.
SHIMA is a crisp sparkling seltzer with real fruit flavor. From the first sip it tastes clean, bright, and refreshing — not medicinal, not chalky. No syrupy sweetness, no artificial aftertaste.
Honest flavor, zero sugar.
Each flavor is built around real fruit notes — juicy peach, crisp citrus, tropical mango. Zero sugar and zero artificial sweeteners mean the taste is clean all the way through.
Calm, balanced energy without the spike.
Within a short time, you may notice a calm, centered feeling — balanced energy that does not spike and does not crash. Many people describe it as focused, sociable, and grounded. Nothing like the edge that comes from high-caffeine drinks.
No crash. No hangover. Just done.
There is no caffeine forcing a comedown. No sugar spike reversing itself at 3pm. When SHIMA wears off, it simply fades — leaving you where you started, not worse.
The Ingredients
What is inside every SHIMA.
Two key ingredients drive the SHIMA experience: kratom extract and L-Theanine. Here is what they are and why they matter.
Kratom is a plant native to Southeast Asia with centuries of use. SHIMA uses a carefully sourced kratom extract, standardized for consistency. Each can contains 38.5mg of mitragynine per serving — a precise, measured dose in a clean delivery format.
L-Theanine is a naturally occurring amino acid well-known among wellness enthusiasts for its role in supporting focused, calm energy — without the jittery edge that caffeine creates. Paired with kratom extract, it shapes the balanced SHIMA experience. This is the same compound that makes green tea feel different from coffee.
A crisp, light carbonated base lets the fruit flavor come through cleanly. No syrupy texture, no heavy mouthfeel, no added sweeteners. Just a refreshing seltzer format that makes SHIMA easy to enjoy any time of day.
Side by Side
SHIMA vs. the energy drink shelf.
Red Bull, Monster, and Celsius all deliver energy through the same mechanism: high-dose caffeine, often combined with sugar. The result is a predictable cycle — spike, jitters, and crash. SHIMA breaks that cycle entirely.
