Energy drinks have changed a lot in the past few years. Zero sugar is close to standard now, and the flavor lineups have moved well past plain citrus into candy, dessert and fruit blends. If you are going to keep something in the fridge for a mid afternoon lift, it makes sense to know what actually sets each brand apart first. Here are seven options worth looking at in 2026, with the flavor ranges, caffeine amounts and formats that make each one different.

1. The Loaded Tea Shop

This is the only entry in the roundup built primarily around a powder packet format rather than a can. A loaded tea is a flavored, caffeinated, zero sugar drink that blends energy tea, B vitamins and sugar free flavoring into a tall iced cup, and it is usually associated with nutrition clubs rather than grocery shelves.

What makes this option practical is the format. The Loaded Tea Shop sells loaded teas as single flavor packets you mix at home, and each packet contains 200 mg of natural green tea caffeine and makes a full 32 ounces of finished drink in about 30 seconds. The packets are zero sugar and zero calories with zero artificial colors or flavors, which is the basis for how the brand describes its own “clean energy” positioning. The brand says it offers more than 40 flavors, including Strawberry Lemonade, Mermaid, Bahama Mama and Watermelon Krawl.

2. Celsius

Celsius is a widely recognized, flavor forward zero sugar option, and it has a broad flavor range. The original 12 ounce can lists 200 mg of total caffeine, 0 g of sugar and 10 calories, with green tea extract, guarana seed extract and vitamin C on the ingredient list.

Current flavors include Kiwi Guava, Fuji Apple Pear, Cherry Cola, Mango Passionfruit and Watermelon, plus several Vibe flavors. There are also separate lines to know about: Essentials in a larger can, On the Go powder sticks that mix into water, and Hydration, which is caffeine free and made with B vitamins and zero sugar.

3. Alani Nu

Alani Nu fits a taste focused roundup because of how it names and builds its flavors. The lineup leans heavily on candy and dessert inspired ideas rather than standard fruit profiles, with current options including Cotton Candy, Sherbet Swirl, Dream Float, Voodoo Vanilla, Cosmic Stardust and Hawaiian Shaved Ice.

The specs are consistent across the range at 200 mg of caffeine and 0 g of sugar per serving, so the decision is really about which flavor idea appeals to you. Alani Nu also lists multi flavor packs such as Sunshine Mix, Beach Blend and Dream Trio alongside its single flavors.

4. Zevia Energy

Zevia is the stevia sweetened entry in this group. Its energy cans are sweetened with stevia extract rather than sucralose or acesulfame potassium, and they list zero sugar, zero calories and 120 mg of caffeine per can.

The classic four flavors are Grapefruit, Kōla, Mango Ginger and Raspberry Lime, with Watermelon and Peach Passionfruit also available. The flavor profiles run more toward soda and sparkling water territory than candy. Zevia also lists a classic four flavor variety pack among its current products.

5. Ghost Energy

Ghost took a different approach to flavor by licensing recognizable candy names. Its canned energy drinks have included Sour Patch Kids Redberry and Blue Raspberry, Warheads Sour Green Apple, Orange Cream and Cherry Limeade, and the 16 fl oz cans list 200 mg of natural caffeine with zero sugar.

Ghost also makes powder energy sticks in a similar vein, including Warheads Sour Berry, Warheads Sour Watermelon and Welch’s Grape. If the licensed flavors are the appeal, the sticks are a way to get them without keeping cans on hand.

6. Monster Ultra

Monster Ultra is the zero sugar side of the Monster range, and it has grown into a long list of flavors. Current options include the original Zero Ultra, Peachy Keen, Vice Guava, Rosá, Blue Hawaiian, Strawberry Dreams, Fiesta Mango, Watermelon and Sunrise, which covers a lot of ground between tropical, berry and light citrus.

The 16 ounce can lists 150 mg of caffeine, 0 g of sugar and 10 calories, which puts it below the 200 mg options above. Ultra also comes in several can sizes, including 12, 16, 19.2 and 24 ounce, so check the label if you are comparing caffeine across the shelf.

7. Red Bull Sugarfree

Red Bull is the lower total caffeine choice in this roundup, with 80 mg of caffeine in an 8.4 fl oz can of Red Bull Sugarfree. The smaller 8.4 fl oz format also means less total caffeine than the 200 mg options elsewhere in this roundup.

Flavor is where the range has expanded. The Editions come in sugarfree versions, including the Peach Edition, the Pink Edition, the Sea Blue Edition, the Iced Edition and the Summer Edition. The sugarfree cans are sweetened with sucralose and acesulfame K.

How to Pick the Right One for You

Four things separate these options in practice. The first is caffeine. Phrases like “no crash” and “no jitters” appear constantly in this category’s marketing, but the more useful comparison is the number printed on the label, and here it ranges from 80 mg in a small Red Bull can up to 200 mg per can or packet.

The second is the sweetener, since most of these are zero sugar but get there differently, whether with stevia extract, sucralose or acesulfame potassium. The third is format, which is where mixes and powder packets stand apart from cans on both storage and the ability to control how strong the finished drink tastes. The fourth is flavor style, and it is worth deciding whether you gravitate toward candy names, fruit blends or something closer to a soda.

Finding One That Fits Your Day

Taste is personal, so nothing on this list will be right for everyone. The useful move is to narrow by caffeine level and sweetener first, then choose the flavor family that sounds good to you. That way the one you end up keeping in the fridge is one you actually want to drink.
