Raspberry Lime Energy Drink - 12 fl oz

Zevia Raspberry Lime Energy does something most energy drinks can't claim with a straight face: it delivers a real, reliable caffeine boost — 120 mg per 12 fl oz can, sourced from tea leaves — with absolutely zero sugar, zero calories, and an ingredient list short enough to read in five seconds.

Each can is sweetened with stevia extract, a plant-derived, zero-glycemic sweetener. Notably, Zevia contains no erythritol — the sugar alcohol that has quietly become ubiquitous in "clean" energy drinks and has drawn increasing scrutiny for its effects at high intake levels. The flavor profile leans into juicy raspberry and bright citrus lime for a tart, refreshing character that doesn't taste medicinal or overly sweet the way artificially flavored competitors often do.

Pick up a conventional energy drink at any gas station or grocery store and you're likely looking at dozens of grams of added sugar per can, synthetic dyes (Red 40, Yellow 5), and a sweetener stack that includes multiple compounds — often erythritol, sucralose, or acesulfame potassium layered together. Zevia's entire sweetener system is one ingredient: stevia extract. The ingredient list has five items. That's not a marketing claim — it's the label.

Nutritional snapshot (per 12 fl oz can): 0 calories · 0 g sugar · 120 mg caffeine from tea leaves.

Common Questions

How does the caffeine amount in Zevia compare to conventional energy drinks?
Zevia Energy delivers 120 mg of caffeine per 12 fl oz can, sourced specifically from tea leaves rather than synthetic anhydrous caffeine. For context, a standard 8.4 fl oz Red Bull contains 80 mg of caffeine, a 16 fl oz Monster contains 160 mg, and a 16 fl oz Celsius contains 200 mg — meaning Zevia sits in a moderate, functional range without pushing into the high-stimulant territory that many people find triggers anxiety or heart palpitations. The Mayo Clinic and FDA both identify 400 mg per day as the generally recognized safe upper limit for healthy adults, so a single Zevia can represents 30% of that threshold. Tea-leaf-derived caffeine enters the bloodstream through the same adenosine-blocking mechanism as synthetic caffeine, so the physiological effect is chemically equivalent.

What is stevia extract and how does it sweeten without affecting blood sugar?
Stevia extract is derived from the leaves of Stevia rebaudiana, a plant native to South America, and the sweetness comes from compounds called steviol glycosides — primarily rebaudioside A (Reb-A) in most commercial applications. These molecules bind to sweet-taste receptors on the tongue the same way sugar does, but unlike sucrose or high-fructose corn syrup, steviol glycosides are not metabolized into glucose in the body. Multiple human clinical trials, including a 2003 study published in Metabolism, have demonstrated that stevia consumption does not raise blood glucose or insulin levels, which is why it registers a glycemic index of zero. This makes it genuinely compatible with low-carb, ketogenic, and diabetic dietary frameworks in a way that erythritol and other sugar alcohols are not always suitable for, particularly for those with sensitive digestion.

Why does Zevia specifically call out that it contains no erythritol, and why does that matter?
Erythritol is a sugar alcohol that has become one of the most common sweeteners in 'clean' or 'zero sugar' energy drinks and functional beverages because it provides bulk and a neutral sweetness profile that masks the slight bitterness of stevia. However, a 2023 study published in Nature Medicine by researchers at the Cleveland Clinic found an association between high circulating erythritol levels and increased risk of cardiovascular events, including heart attack and stroke, though the study was observational and causation was not established. Separately, erythritol is a known GI irritant at doses above roughly 30–50 g per day for many individuals, causing bloating, gas, and loose stools. Zevia's formulation uses stevia extract as the sole sweetener, meaning erythritol is entirely absent from the ingredient list — not reduced, but not present at all. For consumers monitoring their erythritol intake or avoiding it for digestive reasons, this is a meaningful structural difference from competitors like Celsius, Reign, and Bang, which commonly use erythritol or erythritol-plus-sucralose combinations.

Is Zevia Energy genuinely compatible with a strict ketogenic diet?
Yes, with zero grams of sugar, zero net carbohydrates, and zero calories, Zevia Energy does not contribute to carbohydrate intake in any measurable way, making it fully compatible with standard ketogenic protocols that typically cap daily net carbs at 20–50 g. The stevia extract used contains no sugar alcohols that partially count toward net carbs the way maltitol or sorbitol would. Caffeine itself has a mild thermogenic and lipolytic effect — it stimulates the release of fatty acids from adipose tissue via activation of cAMP-dependent pathways — which is consistent with, rather than disruptive to, the metabolic state of ketosis. The drink is also free of B-vitamin megadoses and amino acid blends found in some energy drinks that add trace calories or insulin-stimulating compounds. Vegans and those following gluten-free protocols will also find no conflicts, as the product carries certifications from the Non-GMO Project, the Gluten Intolerance Group, and Orthodox Union Kosher.

How does Zevia's sugar content compare to mainstream energy drinks, and what are the health implications of that difference?
A standard 16 fl oz can of Monster Energy Original contains 54 g of added sugar, and a 16 fl oz Rockstar Original contains 63 g — both delivering sugar loads that exceed the American Heart Association's entire recommended daily limit for men (36 g) or women (25 g) in a single serving. Even a 8.4 fl oz Red Bull Original contains 27 g of sugar. Repeated high-sugar intake is associated with elevated triglycerides, insulin resistance, dental erosion, and energy crashes driven by reactive hypoglycemia — the blood glucose spike and subsequent drop that follows rapid sugar absorption. Zevia contains 0 g of sugar, so none of these mechanisms are triggered by the drink itself. The practical consumer experience this translates to is a lift driven purely by caffeine's adenosine-receptor blockade, without the secondary glucose spike and crash layered on top of it.

What do Zevia's certifications actually verify, and how can I confirm them independently?
The Non-GMO Project Verified seal means Zevia's ingredients and supply chain have been audited against the Non-GMO Project Standard, which includes testing at risk points for GMO presence — you can verify any product's participation at nongmoproject.org by searching the brand. The Certified Gluten-Free seal from the Gluten Intolerance Group (GIG) requires products to meet a standard of less than 10 parts per million of gluten, which is a stricter threshold than the FDA's 20 ppm standard for 'gluten-free' labeling — GIG maintains a searchable verified products database at gffs.org. The Kosher certification from the Orthodox Union (OU) confirms that ingredients, processing facilities, and production runs have been inspected by OU rabbinical supervisors; the OU database at oukosher.org allows verification by product name. These are third-party audited certifications with publicly searchable registries, not self-declared labels — which distinguishes them from claims like 'natural' or 'clean,' which carry no regulatory definition.

Can Zevia Energy be used as a substitute for coffee or tea in daily caffeine routines?
At 120 mg of caffeine per can, Zevia Energy delivers a dose closely comparable to a standard 8 oz drip coffee (roughly 95–165 mg depending on brew strength and bean variety) and considerably more than a typical cup of black tea (40–70 mg per 8 oz). Since the caffeine is derived from tea leaves rather than synthetic anhydrous caffeine, the source compound is the same alkaloid — C8H10N4O2 — so there is no pharmacological distinction in how the body processes it. People who find coffee irritating to the stomach may find carbonated stevia-sweetened drinks more tolerable, since the absence of coffee's high chlorogenic acid content removes a common GI irritant. The zero-calorie, zero-sugar profile means it doesn't introduce the dairy, added syrups, or sugar that many coffee drinks accumulate. It is shelf-stable and canned, making it a more portable format than brewed coffee for workplaces, travel, or pre-workout contexts where brewing isn't practical.
