Grapefruit Energy Drink - 12 fl oz

The energy drink category is crowded with products that swap one problem for another — sugar for sucralose, sucralose for erythritol, erythritol for a wall of unpronounceable additives. Zevia Grapefruit Energy cuts through all of it with five simple ingredients: Carbonated Water, Natural Flavors, Citric Acid, Stevia Extract, and Caffeine. That's the entire list.

The sweetness comes entirely from stevia extract — a plant-derived zero-calorie sweetener with no glycemic impact — and the caffeine is derived from tea leaves, not synthesized from scratch. The result is a zero-sugar, zero-calorie carbonated energy drink that delivers a real caffeine boost without the blood-sugar rollercoaster, the artificial dyes, or the erythritol that has been appearing in an increasing number of "better-for-you" energy products.

Zevia Grapefruit Energy carries Non-GMO Project Verified status, is Gluten-Free Certified by the Gluten Intolerance Group (a third-party audit, not a self-declaration), is certified Kosher by the Orthodox Union, and is vegan. It explicitly does not contain erythritol — a claim worth noting as erythritol is now a standard ingredient in many competing zero-sugar beverages.

With zero calories and zero grams of sugar, it fits keto, vegan, and gluten-free dietary frameworks without compromise; those following a paleo-leaning or low-carb lifestyle will also find nothing here to break their protocol. Geographic origin information for the stevia and other ingredients is not disclosed by the brand, so sourcing region cannot be confirmed at this time. For anyone searching for a clean energy drink with no artificial sweeteners, the five-ingredient label is the answer most cans won't give you. Shelf stable; no refrigeration required before opening.

Ingredients: Carbonated Water, Natural Flavors, Citric Acid, Stevia Extract, and Caffeine.

Common Questions

How does Zevia Grapefruit Energy compare to a conventional energy drink on sugar and additives?
A standard 16 oz conventional energy drink typically contains 50–54 grams of added sugar and often includes synthetic caffeine, artificial colors (like Red 40 or Yellow 5), and artificial flavors. Zevia Grapefruit Energy contains zero grams of sugar and zero calories, is sweetened with stevia extract instead of high-fructose corn syrup or sucrose, and uses no artificial colors or flavors. The ingredient list has five items total — compared to 15–20 on many mainstream energy cans.

What is the caffeine source, and how does tea-leaf-derived caffeine differ from synthetic caffeine?
Zevia's caffeine is derived from tea leaves, which is a natural extraction process. Synthetic caffeine — the type found in most conventional energy drinks — is chemically synthesized from urea and chloroacetic acid, and is absorbed more rapidly by the body, which can produce a sharper spike and faster crash. Tea-leaf-derived caffeine is absorbed more gradually. The total caffeine content should be confirmed on the can's Supplement Facts panel, as it varies by flavor and size.

Is Zevia Grapefruit Energy safe for someone following a keto diet?
Yes. Zevia Grapefruit Energy contains zero grams of sugar and zero net carbohydrates, making it fully compatible with ketogenic dietary protocols. It is sweetened with stevia extract, which has no glycemic index and does not trigger an insulin response in clinical studies. It also does not contain erythritol, a sugar alcohol used in many keto-marketed products that can cause digestive discomfort in some people.

What does the Non-GMO Project Verified certification actually mean for this product?
Non-GMO Project Verified means every ingredient in Zevia Grapefruit Energy — including the stevia extract and citric acid — has been evaluated against the Non-GMO Project Standard, which requires ongoing testing and supply-chain traceability for ingredients at risk of genetic modification. This is a third-party audit, not a self-declaration by Zevia. The butterfly seal on the can means an independent certifier reviewed the formulation and supply chain.

Does this product contain erythritol, and why does that matter?
Zevia explicitly confirms this product does not contain erythritol. This matters because erythritol — a sugar alcohol widely used in zero-sugar and keto-marketed beverages — has come under scrutiny in recent cardiovascular research (a 2023 Nature Medicine study found associations between high erythritol blood levels and cardiovascular events, though research is ongoing). Separately, erythritol is a known digestive irritant at higher doses. Zevia's use of stevia extract as the sole sweetener sidesteps both concerns.

What does the Gluten-Free Certified badge from the Gluten Intolerance Group mean versus a brand's self-declared gluten-free label?
The Gluten Intolerance Group (GIG) is an independent third-party certifier whose GFFS (Gluten-Free Food Service) and GFCP certification programs require testing to below 10 parts per million of gluten — stricter than the FDA's voluntary 20 ppm threshold for self-declared gluten-free labeling. A brand can print 'gluten-free' on a label without any third-party verification. GIG certification means an external auditor confirmed the standard was met.

How can Zevia Grapefruit Energy be used beyond a standard energy drink?
Because it is shelf-stable, zero-sugar, and carbonated, Zevia Grapefruit Energy works well as a mixer in zero-proof cocktails (pair with fresh mint and lime for a mocktail with structure), as a base for a sparkling grapefruit spritzer with a splash of elderflower, or as a morning alternative to coffee for those sensitive to high caffeine doses who prefer a lighter lift. The grapefruit flavor profile is bright and citrus-forward, pairing well with savory snack breaks.
