Energy gummies sit in a useful spot for runners who want carbohydrate without the slick, syrupy mouthfeel of a gel. The category covers products that range from 19 g of carbs per serving up to 48 g per pouch, with sodium ranging from about 30 mg to 100 mg, and with sugar profiles built around cane syrup, tapioca syrup, real fruit, honey, or pure maple syrup. This ranking compares 9 widely available brands against published label data and reputation in the running community, so a runner choosing a chew for a long session has a single reference for what each one delivers, where each one fits, and where each one falls short.
The framework below uses carbs per serving, glucose-to-fructose ratio, sodium, caffeine availability, sugar source, texture during sustained activity, and packaging. The ranking reflects how well each brand performs against that combined picture, not against any single criterion in isolation.
Comparison Framework and Test Criteria
A useful comparison of running gummies starts with carbohydrate density, because that figure decides how many packets a runner has to carry on a long session. The standard target during sustained effort runs from 30 to 60 g of carbs per hour for moderate output, scaling toward 60 to 90 g per hour at higher intensities. Products fall into 2 general groups. Lower-density chews supply 19 to 24 g per serving and ask the runner to eat several pieces over the course of an hour. Higher-density pouches deliver 39 to 48 g in a single packet, which simplifies carry but compresses sugar intake into a shorter window.
The second variable is the glucose-to-fructose ratio, because the body absorbs glucose and fructose through separate intestinal transporters, and a blended ratio raises the ceiling on hourly intake. Research on dual-source carb mixes points to ratios between 2:1 and 1:0.8 as the most studied for endurance use. Brands that publish their ratio (PowerBar, SiS) make this easy to verify. Brands that lean on real fruit, honey, or maple introduce the same blend through nature, though the proportions are less precise.
Sodium per serving matters more on long, hot runs and matters less on cool sessions where sweat losses stay modest. Standard chew sodium runs 30 to 80 mg per serving, with 2 outliers that lift sodium for hot-weather use. Caffeine variants exist in most lines, and dosing ranges from 20 mg per serving (a light lift) to 75 mg per pouch (a meaningful stimulant load). Texture is the final variable and the one that separates a chew that works during a 22 km tempo from a chew that gums up between molars at mile 14. Firmer cubes hold up to ambient heat better than softer chews, and they also stick to teeth more, which is a real complaint at higher running paces. Packaging closes the picture, because a pouch that opens with one hand at race pace is operationally different from a pouch that needs both hands and a stationary minute.
To make a 9-brand comparison feasible at the household level, this ranking treats each product as a single-serve item rather than a 12-pack commitment. The Feed sells most of these brands as individual packets, which lets a runner sample across the field without committing to a full bag of any one product up front.
Clif Bloks
Clif Bloks have been the reference cube in the category for over a decade. Each serving delivers 24 g of carbs across 3 dice-shaped cubes, with 50 mg of sodium in standard flavors and 100 mg in the Salted Watermelon variant. The sugar source is organic tapioca syrup, organic dried cane syrup, and organic maltodextrin. Caffeine is available across several flavors, including Black Cherry at 50 mg per pouch and Tropical Punch and Orange at 25 mg.
The texture is the brand’s signature. Clif Bloks chew dense, almost like an industrial gummy bear, and they hold their shape in pocket heat better than softer competitors. The trade-off is well documented in running community threads. The cubes can stick to molars during sustained running, especially at higher heart rates when saliva production drops. Many runners report cutting Bloks in half before a race or letting the cube soften in the mouth before chewing, which sidesteps the sticking problem while preserving the carb load.
GU Energy Chews
GU Energy Chews position themselves as the softer, faster-eating alternative to Clif. A serving is 4 chews and supplies 22 g of carbs with 40 mg of sodium. The full pouch is 8 chews and 44 g of carbs. The Strawberry flavor includes 20 mg of caffeine, which sits at the lighter end of the caffeinated chew range and works well as a mid-run lift without being aggressive. Other flavors stay caffeine-free.
A distinctive feature is the inclusion of 400 mg of branched-chain amino acids per serving, including leucine, valine, and isoleucine. The functional benefit during a single long run is modest, but for runners doing back-to-back long sessions in a marathon block, the BCAA content is one input that supports recovery. Texture is softer than Clif Bloks, with a slight tackiness that some runners report as easier to chew at pace and others report as more apt to dissolve into a paste in warm pockets. Flavor reception in community reviews tends toward positive on Watermelon and Blueberry Pomegranate.
Honey Stinger Organic Energy Chews
Honey Stinger leans on organic honey and tapioca syrup as the primary sugar source, which gives the brand a distinct profile in the category. A full pouch delivers 39 g of carbs with 65 mg of sodium. The line is USDA Organic and gluten-free, which matters for runners who track those certifications. Standard flavors are caffeine-free, and the Caffeinated Cherry Cola variant carries 32 mg of caffeine per pouch.
Texture is the closest of any brand on this list to a mainstream fruit snack. The chews are softer, more pliable, and easier on the jaw at running pace than the firm Clif cube. The honey base produces a flavor profile that runners either love or find too sweet by mile 18. Pink Lemonade and Cherry Blossom tend to draw the most positive reviews. The pouch design is simple and resealable in name only, which makes mid-run portioning a small operational issue rather than a real one.
Skratch Labs Sport Energy Chews
Skratch takes a real-fruit position. A serving delivers 19 g of carbs with 80 mg of sodium, which is the highest stock sodium load of any chew in this comparison and useful for runners on hot, salty efforts. The full pouch is 40 g of carbs over 2 servings. The sugar source is cane sugar, tapioca syrup, grape juice concentrate, and freeze-dried real fruit, with no artificial flavors, colors, sweeteners, or waxes. The Matcha Green Tea & Lemons variant carries 50 mg of caffeine.
The texture is softer and more hydrated than the other firm-cube competitors, which Skratch attributes to using slightly more water in the formulation. The trade-off is that Skratch chews soften further in heat and can be harder to extract cleanly from the pouch in summer conditions. Flavor in the brand’s lineup leans bright and tart, and Raspberry and Sour Cherry are particularly well regarded in long-run community feedback.
PowerBar PowerGel Shots
PowerGel Shots are the densest carb-per-pouch product in this comparison. A full pouch supplies 48 g of carbs with 30 mg of sodium and a C2Max dual-source carb mix that runs roughly 2:1 glucose to fructose, which is the historically dominant ratio for high-intake endurance fueling. Standard flavors are caffeine-free, while the Cola variant includes 75 mg of caffeine, which is the highest caffeine load in the comparison.
The texture is a hybrid. Each piece is a chew with a liquid filling, which means a runner can choose to chew it whole or bite it open and let the gel center come through first. This format is useful at higher paces where chewing is harder. The tradeoff is that PowerGel Shots include gelatin, which removes them from the vegan column, and some flavor variants contain wheat. Sodium per gram of carb is the lowest in the comparison, so PowerGel Shots pair best with a separate electrolyte source on long sessions.
SiS Beta Fuel Chews
SiS Beta Fuel Chews carry the highest carb density per pouch in the comparison along with PowerGel, at 46 g of carbs and 190 kcal per pouch. The product is built around the 1:0.8 maltodextrin-to-fructose ratio that SiS adopted after research from 2013 suggested it produced higher carbohydrate oxidation than the older 2:1 standard. Sodium is not the focus of the product, and the chew functions as a dedicated fueling tool rather than an electrolyte product.
Texture sits closer to Clif than to Skratch, with a firm chew that holds shape in heat and asks for thorough chewing during running. The orange and lemon flavors are the most established. The brand’s positioning is squarely on athletes targeting 80 to 120 g of carbs per hour, which suits ultra-distance road running and longer triathlon legs more than it suits a 60-minute tempo. For shorter sessions the carb load per pouch may exceed what a runner needs in a single dose, and splitting the pouch over time is the practical approach.
Maurten Solid C 160
Maurten does not currently produce a true gummy, and the closest chewable in their lineup is the Solid C 160. A bar weighs 55 g and delivers 40 g of carbs through a fructose-glucose syrup, oat flakes, maltodextrin, sugar, and rice flour. The bar is vegan, low-fiber, and built on the same hydrogel logic that defines Maurten’s gels. Cocoa is the flavor in the C variant, with a mild chocolate, oat-forward profile.
The product is included here as a comparison reference rather than as a direct gummy. The texture is more like a soft energy bar than a chew, and the bar splits cleanly into 2 pieces of 20 g of carbs each, which makes mid-run dosing simple. For runners with sensitive stomachs who have rejected gummy formulations on GI grounds, the Solid C is a category-adjacent option worth running through the same comparison framework. The cost per gram of carb is higher than any other product on this list, which keeps Solid C as a race-day or key-session item for most runners rather than a daily training fuel.
UnTapped Maple Products
UnTapped does not yet sell a true chew, and the brand is included here for the same reason as Maurten Solid C. Their closest single-source-natural-sugar option is the Maple gel packet, which delivers 26 g of carbs from pure organic Vermont maple syrup. The Mapleaid product in the line is a powdered hydration mix rather than a chew. UnTapped’s Maple Stroopwafel is a related product that runners often pair with the gel for longer sessions.
The argument for UnTapped sits in the sugar source. Pure maple syrup is naturally a low-glycemic carbohydrate with a built-in glucose-fructose-sucrose mix, plus trace minerals including potassium, manganese, and zinc. Runners with persistent GI issues on synthetic sugar blends often report cleaner sessions on maple. The catch is that no UnTapped product currently sits in the chew category, so a runner committed to gummies has to decide if UnTapped belongs in the comparison or sits outside it. For this ranking, the brand is treated as a category-adjacent natural-sugar reference rather than a chew competitor.
Näak Boost Energy Gel
Näak’s chewable category is similarly thin. The Boost Energy Gel delivers 25 g of carbs per 32 g packet from agave powder, dehydrated tapioca syrup, and dextrose, while the Ultra Energy line adds canola protein isolate and BCAAs. Sodium varies by product. The Boost neutral drink mix carries 250 mg per serving, while a Salted Cucumber drink variant carries 500 mg.
Näak is included here because the brand’s protein-plus-carb approach is uncommon among gummy and gel products and represents a different fueling philosophy. For ultra-distance runners who need extended fueling beyond 5 hours, the protein addition has a more credible case than it does for a marathon-distance session. As with UnTapped, the lack of a true gummy product means Näak functions as a category-adjacent reference rather than a chew competitor head-to-head.
How Do You Test Multiple Energy Gummy Brands Without Buying Full Bags?
Buying a full retail bag of every chew on this list runs into 9 separate $30 to $40 commitments before a runner has any idea which one suits their stomach, jaw, and pace. The math gets worse on the brands sold in 12-packs. The cleanest way around this is to assemble a custom box of single-serve packets from a retailer that sells individual servings rather than full bags. The Feed builds custom boxes of single-serve nutrition packets, which means a runner can put one packet of each of the 9 brands into a single box and run a structured comparison over the course of a marathon training block without committing to any one product up front.
The practical workflow that follows is simple. Pick a long run schedule, assign one chew to each session, log the variables that matter, and treat the comparison as data rather than impression. Useful variables include total carbs consumed, time of first dose, time of last dose, GI response, jaw fatigue, ease of opening the packet, residual stickiness, and finishing energy at the back end of the run. Across 9 long sessions, the field narrows naturally, and the runner ends the cycle with a defensible product choice for race day rather than a hunch.
Final Ranking and Where Each Brand Fits
The ranking below reflects how each product performs against the combined framework of carbs per serving, sodium, sugar source, texture during running, and packaging.
The top tier in the dedicated gummy category is occupied by Clif Bloks, GU Energy Chews, and Skratch Labs. Clif Bloks earn the top position for the depth of caffeine and sodium options across the line and for the consistency of the cube format. GU Energy Chews take the second slot for the BCAA addition and softer chew. Skratch Labs ranks third for the highest stock sodium load and the cleanest sugar source, balanced against a softer pouch in heat. SiS Beta Fuel Chews ranks fourth for athletes needing high carb density per pouch and the 1:0.8 ratio. PowerBar PowerGel Shots ranks fifth for the liquid-filled hybrid format and the strongest caffeine option. Honey Stinger sits sixth for the honey-forward flavor profile and softer chew, with the carb-density advantage offset by lower sodium and a sweeter taste fatigue curve. Maurten Solid C ranks seventh as the category-adjacent solid for stomach-sensitive runners. UnTapped and Näak round out the bottom of the comparison only because neither currently produces a true chew, and a runner committed to the gummy format has to step outside their lineup to fuel.
A reader running their own version of this comparison can do it in a single training block. The Feed is the most direct path to a custom box of single-serve packets that covers the field, which keeps the test affordable and lets the comparison rest on the runner’s own data rather than community consensus.
Frequently Asked Questions
Are energy chews better than gels for running?
Neither format is universally better. Chews give a runner control over portion size and the option to space carbs across smaller doses, which suits steadier paces and runners who tolerate solids well during effort. Gels deliver carbs faster and pack smaller, which suits race-pace efforts where chewing is harder. Most marathoners settle on one format after a training block of structured testing.
How many energy chews should I eat during a marathon?
Most chew packets supply 22 to 48 g of carbs, and the standard intake target during a marathon is 30 to 60 g of carbs per hour for most runners, with elite athletes pushing 80 to 120 g per hour. A 4-hour marathon at the lower end of that range needs at least 120 g of carbs across the race, which works out to roughly 3 to 6 chew servings depending on the brand. Practice the dosing in training before applying it on race day.
When should I start using energy chews on a long run?
The first dose can come 5 to 15 minutes before the run starts, which tops off liver glycogen. After that, most runners begin in-run dosing once they cross 45 to 60 minutes of continuous effort, then repeat every 20 to 45 minutes depending on intensity. Sessions under 60 minutes generally do not require any in-run carb intake.
Are energy chews easier on the stomach than gels?
Many runners report that chews sit better in the gut than gels, partly because the slower chew rate spreads sugar intake over a longer window and partly because the texture feels more like food. The effect is individual. Runners with persistent GI issues sometimes do better on natural-sugar products like UnTapped maple gel or hydrogel-based products like Maurten, both of which target stomach comfort directly.
Do energy chews stick to your teeth when running?
Firmer chews like Clif Bloks and SiS Beta Fuel Chews are more apt to stick to molars during sustained running than softer chews like Honey Stinger or Skratch Labs. The effect gets worse at higher heart rates when saliva production drops. Cutting cubes in half, letting the chew soften in the mouth before chewing, and rinsing with water after each dose all reduce the problem.
How much caffeine is in energy chews?
Caffeine content ranges widely. GU Energy Chews Strawberry carries 20 mg per serving, Honey Stinger Caffeinated Cherry Cola carries 32 mg per pouch, Clif Bloks caffeinated flavors run 25 to 50 mg per pouch, Skratch Matcha Green Tea & Lemons carries 50 mg per serving, and PowerGel Shots Cola carries 75 mg per pouch. Athletes who want a caffeine ramp during a marathon often start with a lower dose at the half and a higher dose in the final third.
