The 13 Best Keto Energy Drinks

1. Zevia Zero Sugar Energy Drink 

If you’re looking for a keto energy drink that delivers a refreshing punch without derailing your dietary goals, then Zevia Zero Sugar Energy is for you. Each 355ml can (regardless of flavor) boasts zero grams of carbohydrates and zero calories, offering a light sip whenever you need a refreshing energy boost. Packed with a moderate 120mg of caffeine, it provides the perfect pick-me-up without the dreaded jitters. 

Sweetened naturally with stevia leaf extract, Zevia avoids the potential drawbacks associated with artificial sweeteners, which, according to the National Heart, Lung and Blood Institute (NHLBI), can have negative health effects. However, while stevia is generally considered safe, some people may experience digestive discomfort with excessive consumption. Overall, this keto energy drink offers a delightful blend of flavor and function, adding some excitement to a ketogenic lifestyle.

2. Jocko GO 

Here to effortlessly shake up your routine — with a clean, no-nonsense approach to energy — is Jocko GO. This sugar-free powerhouse fuels you without the carb crash, with just one gram of carbs and zero sugar, making it a solid pick for keto energy drinks. Each can of Jocko GO is loaded with natural caffeine (95mg) and nootropics like theobromine and alpha-GPC for focus.

Sweetened with monk fruit and fermented sugar cane, it skips artificial junk to reveal a more natural, earthy vibe, so don’t expect an ultra-sweet soda feel. But as with all energy drinks, zero sugar or not, moderation is key — too much caffeine can spike heart rate and blood pressure.

3. EBOOST Super Fuel

Packed with natural caffeine, nootropics and vitamins, EBOOST Super Fuel is a keto energy drink that keeps you sharp and energized without the crash. Each can delivers 110mg of caffeine from green coffee beans and green tea — just enough to wake you up without the jitters. 

This keto energy drink comes in four refreshing flavors, with just 2g sugar, 3-4g carbs and under 15 calories. Plus, the added electrolytes support hydration, making it great for workouts or long days. Just don’t overdo it — too much caffeine can still mess with your sleep.

4. Red Bull Sugarfree

A go-to among keto energy drinks, Red Bull Sugarfree is a classic with a sugar-free revamp, still delivering the familiar boost — with the help of wings. Each 250ml can contain 10 calories, 3g carbs and 80mg of caffeine (about the same as a cup of coffee). It also includes taurine and B vitamins to support alertness and performance. 

However, it does contain artificial sweeteners like sucralose, which, according to the National Institutes of Health, may have potential health concerns if consumed frequently or in large quantities. Therefore, moderation is key when reaching for products containing these additives.

5. Rockstar Pure Zero - Fruit Punch

It’s no surprise that Rockstar Pure Zero Fruit Punch is your keto-friendly jolt of energy in a 473ml can. Packed with 240mg of caffeine, it delivers a serious pick-me-up — whether you're powering through a workout or locked in a meeting with an afternoon slump. Each serving is bursting with bold fruit punch flavor while keeping things low-carb at just 20 calories and 2g carbs. 

This fruity keto drink contains artificial sweeteners such as erythritol. According to research highlighted by the National Institutes of Health (NIH), erythritol consumption has been linked to an increased risk of cardiovascular events, though further studies are needed. As a precaution, moderation is advisable when consuming products containing erythritol.

6. GURU Lite 

Unlike other artificial-laden keto energy drinks, GURU Lite keeps it clean by leaning on organic green tea, guarana and ginseng for a smooth, jitter-free boost. With 100mg of caffeine providing steady energy and just 25 calories and 5g carbs per can, it’s the perfect keto energy drink.

Plus, it skips synthetic sweeteners, opting for a touch of organic stevia instead for a naturally light sweetness. While it’s a solid choice if you’re avoiding sugar, the caffeine content can still add up if you’re not careful — so, as always, moderation is key. But otherwise, if you want a plant-based energy lift without any artificial additives, GURU’s got you.

7. Yerbaé

If a keto energy drink promises crisp, fruit-flavored, plant-based energy, who wouldn’t jump at the chance for an invigorating boost? Yerbaé delivers all that and more with a 100% commitment to zero — zero carbs, zero sugar and zero calories.

Taking it a step further, this keto-friendly energy drink gets its energy kick from yerba mate and white tea, packing 160mg of caffeine per can. It’s also free from artificial sweeteners and loaded with antioxidants from real lemons. While these natural caffeine sources tend to be gentler on the system, too much can still mess with your sleep — so sip smart.

8. Feel Energy Drinks

Feel free to crack open a can of Feel Energy Drinks and enjoy refreshing fruity flavors with a natural energy boost — all without wrecking your keto goals. With absolutely no sugar, calories or carbs per can, it’s a refreshing alternative to sugary energy drinks.

The caffeine kick (140mg) in this keto-friendly energy drink comes from green coffee bean extract, providing smooth, sustained energy. It also includes beneficial B vitamins and amino acids like L-theanine, which, according to research shared by PubMed, may support focus, endurance and cognitive performance. Whether you need a pick-me-up or simply something crisp and refreshing, this drink delivers sustained energy without the jitters.

9. Hiball Energy Seltzer - Vanilla

Among the keto energy drinks on this list, Hiball Vanilla Energy Seltzer is a rare find — a no-calorie, no-carb drink with a vanilla twist? Yes, please. It ditches sugar and artificial sweeteners, relying instead on organic caffeine (160mg from guarana and ginseng) for a boost sponsored by nature.

Packed with vitamins B3, B5, B6 and B12 for extra goodness, it keeps things clean and simple. With no sweeteners, the flavor is subtle, making it a love-it-or-leave-it choice, but definitely worth a try. If you're after a balanced, lightly vanilla-infused healthy drink that won’t mess with your macros, Hiball delivers.

10. Kill Cliff Ignite - Smashing Citrus

Clean ingredients and even cleaner energy are what Kill Cliff Ignite keto energy drinks are all about. The Smashing Citrus flavor delivers a refreshing burst of orange and lemon sans sugar and with just one gram of carbs. Fueled by 150mg of caffeine from green tea and fortified with B vitamins, it provides a steady boost to prevent a crash. 

Kill Cliff also contains electrolytes like sodium and potassium to support hydration, making it a solid midday pick-me-up. Better yet, it is ideal fuel before, during or after a run. The added ginger root extract isn’t just for flavor; according to Johns Hopkins Medicine, ginger can aid digestion and help reduce inflammation, adding another layer of benefits and securing its spot as one of the best keto energy drinks.

11. Monster Energy Zero Ultra

If you’re after the classic Monster kick without the sugar overload, Monster Energy Zero Ultra has you covered. This keto energy drink contains just 6g carbs, 10 calories and no sugar. Crisp, lightly citrusy and refreshingly smooth, it’s like a sparkling lemonade with an energy punch.

With 150mg of caffeine, B vitamins and taurine, this keto energy drink delivers sustained focus and endurance without the sugar crash. The catch? It relies on artificial sweeteners like sucralose to keep things sweet without extra calories — something to keep in mind if you’re watching your intake.

12. Red Bull Total Zero

A step up from sugar-free, Red Bull Total Zero lives up to its name with zero calories, carbs and sugar, making it a top keto energy drink. Each can packs 80mg of caffeine (about the same as a small coffee), taurine, B vitamins and sucralose for a balanced boost. 

While it’s crisp, refreshing and delivers a solid midday jolt, the artificial sweeteners might make you think twice between sips. Nevertheless, it remains one of the top keto energy drinks out there.

13. Bang Energy

Not at all shy about delivering a serious caffeine punch, Bang Energy packs 300mg per can — about the same as three cups of coffee combined. It’s a go-to for anyone needing maximum energy ASAP. With zero carbs, it’s a fully keto energy drink, sweetened with sucralose for a bold, candy-like taste. It also boasts CoQ10 and electrolytes, adding an extra sprinkle of the good stuff. 

While Bang delivers a jitter-free lift for most, the ultra-high caffeine might be intense for some. If you're after sustained energy and don’t mind an artificial sweetness, the Bang energy drink flavors will keep you going.

What Is the Best Keto Energy Drink?

When it comes to keto energy drinks, Yerbaé is a solid choice, ditching sugar, carbs and artificial sweeteners while still delivering a reliable caffeine boost. Zevia Zero Sugar Energy Drink is a close second, offering zero carbs and calories while using stevia leaf extract instead of artificial sweeteners.

When shopping for keto energy drinks, look for zero-sugar options and, if possible, choose those sweetened with natural alternatives like stevia. Try to avoid hidden carbs from fruit juice, maltodextrin or artificial fillers. Keep an eye out for electrolytes — think sodium, potassium and magnesium — which help combat keto-related dehydration and fatigue.

Are Sugar-Free Energy Drinks Keto-Friendly?

The answer is yes! Most zero-sugar energy drinks are keto-friendly but not all are created equal. Many rely on artificial sweeteners like sucralose or acesulfame K, which won’t impact blood sugar and are safe for keto. Others use stevia, a natural alternative that also won’t kick you out of ketosis. 

However, be cautious — some so-called keto energy drinks sneak in hidden carbs from dextrose or fruit juice, which can spike insulin levels. Always check the label for zero carbs and no added sugars to ensure you’re consuming only the healthiest energy drinks.

With so many keto energy drinks available, you don’t have to sacrifice energy or flavor while sticking to your low-carb lifestyle. Whether you prefer natural caffeine, sans sugar or added electrolytes, there’s a perfect option to fuel your day without breaking ketosis. Just be sure to check labels twice to keep your energy clean and keto-approved — then power up and keep crushing your keto goals, one sip at a time!
