10 Best Energy Supplements For Running in 2026

Each packet delivers 100 calories and essential electrolytes from a dual-source blend of maltodextrin and fructose, which uses non-competing pathways for absorption. This design aims to provide efficient fuel for activities like running or biking. The formula also includes branched-chain amino acids intended to help decrease muscle damage and mental fatigue.

The trade-off is the modest caffeine and sodium levels. If you’re a heavy sweater or rely on a significant caffeine kick, you might find yourself wanting more. For those seeking a higher-stimulant option without switching brands, the GU Roctane Energy Gel is the logical in-family upgrade. This original gel remains the dependable workhorse, perfect for dialing in your personal fueling strategy without overcomplicating things.

Maurten’s hydrogel technology delivers 100mg of caffeine and 25g of carbohydrates for a very specific runner. It’s designed for athletes who need a potent, fast-absorbing fuel source with a significant stimulant kick to power through the latter stages of a long effort, all while minimizing gastrointestinal distress. This makes it a premium choice for experienced endurance athletes who have struggled with stomach issues from conventional syrup-based gels and who perform well with caffeine.

Its carbohydrate payload is notably lower than some other high-endurance options, like the Maurten Gel 160, which packs 40g. For runners who prioritize sheer fuel density over a caffeine boost, or who are sensitive to stimulants, this gel’s specific formulation might be over-engineered. It’s a precision tool, not a universal one.

A 100% all-natural ingredient list built from fruit puree and chia seeds means your digestive system gets real food it can process without distress. This makes the Hüma Gel a standout for runners whose performance has been hampered by stomach issues from synthetic maltodextrin or dextrose. The finely milled chia seeds help provide a steady energy release, which suits athletes who prefer a more gradual fuel over a sharp sugar spike.

This natural formula doesn’t pack the sheer carbohydrate density of a lab-engineered option like Maurten’s. You’re choosing digestive comfort over maximum carb-per-ounce efficiency. The variety pack offers a smart way to sample flavors, though the exact mix depends on availability, so you might not get your preferred caffeine level in every order.

The USDA Organic certification is the headline here, offering a clean, natural fuel source for runners who prioritize ingredient purity. With 24 grams of carbohydrates intended for quick uptake, it provides a straightforward energy boost without caffeine, making it a sensible choice for athletes who react poorly to stimulants or train later in the day. The inclusion of potassium adds a basic layer of electrolyte support, rounding out its role as a simple, digestible gel.

This means you might need to consume more frequently on very long efforts to match the fueling rate of denser gels.

A 30-gram carbohydrate hit is the central feature here, designed to deliver a substantial fuel dose in one go. This makes it a straightforward choice for runners who need maximum carbs from a single gel and want to minimize the number of packs they carry. The deliberately mild, neutral flavor is a logical move to prevent taste burnout over many hours, suiting athletes who find sweet flavors cloying during long efforts.

Its specialization is purely as a high-carb vehicle without the added caffeine or electrolytes listed for some caffeinated competitors. That means you’re managing those elements separately from your fuel. The long, slim package is efficient for stuffing into pockets, but it’s a different form factor compared to the more cubical packs of something like GU Energy Gels.

GU Energy Roctane Energy Gel contains three times more sodium than the brand’s original formula, providing a practical defense against cramping and fading focus during multi-hour events where significant sweat loss occurs. Its formula layers a substantial amino acid complex with dual-source carbohydrates, aimed at delaying fatigue for sustained efforts. This makes it suitable for the ultra-runner or endurance athlete who needs more than just sugar to get through their longest days.

You trade some convenience for its heft and specialized formula. A full box of 24 gels weighs 1.7 pounds, a substantial amount compared to lighter single-serving options. While the amino acids and high sodium offer a clear advantage for ultra-endurance, the formula is more complex than a basic carbohydrate gel. For shorter distances, a simpler option from the GU Energy Original line could suffice.

The formulation delivers 19 grams of quick-absorbing carbohydrates from a glucose and fructose blend, providing a steady stream of fuel without relying on thick gels. This makes it a strong match for runners who experience stomach distress from traditional options or simply dislike their texture. The real fruit flavor and lack of artificial ingredients further reduce the risk of GI issues, which is a common point of failure in endurance nutrition.

Skratch Labs Energy Chews contain less carbohydrate per serving than a standard gel, so you might need to consume more volume for equivalent fueling. They prioritize gentleness and palatability over the maximum carb density and stimulant support found in Maurten’s Gel 100, which packs 25g of carbs and 100mg of caffeine into a single pouch. It’s a deliberate choice for comfort over compactness.

Each serving of these energy chews contains 50mg of caffeine, providing a moderate boost for endurance activities without the intense spike of a high-dose gel. The plant-based, non-GMO cubes also supply 24g of carbohydrates and sodium for electrolyte replacement, making them suitable for longer sessions where athletes prefer ingredients like organic tapioca syrup. Their soft, not-too-sticky texture offers an alternative to traditional gels for those who favor a chewable format.

Portability is the compromise. A box of 18 packs has some heft compared to a handful of foil gel packets, and the act of chewing isn’t for everyone during intense effort. For a pure, higher-caffeine punch in a more compact form, Maurten’s caffeinated gel delivers double the caffeine. But if you distrust straight gels or want a slower, more manageable intake of carbs and stimulant, these chews are a reliable mid-range choice.

The 40 grams of carbohydrates packed into a single Maurten Gel 160 is its defining feature. This high capacity makes it a serious fuel for long-distance runners and triathletes who need to maximize calorie intake per hour and minimize how many packets they have to open and consume. The patented hydrogel technology is the key here, it’s engineered to move those carbs past the stomach for absorption, which directly addresses the gastrointestinal issues that derail so many marathon and ultra efforts. For an athlete whose primary need is sheer, reliable fuel volume with minimal fuss, this gel is built for that job.

Such a concentrated dose isn’t for everyone. If your gut can’t handle 40 grams of carbs at once, you’d be better served with a lower-dose option such as Maurten’s caffeinated gel or the one from Precision Hydration, where you can titrate intake more finely. This isn’t a versatile, all-purpose gel; it’s a specialized tool for when your main problem is getting enough fuel onboard during the longest, most demanding events.

A 15-serving box with three distinct flavors means you can experiment across several long training blocks without committing to a single taste. This is the clear pick for runners who get bored easily or who are still figuring out their palate preferences. The inclusion of sodium and potassium addresses a key cramp-prevention need, and the complete lack of caffeine makes it a safe bet for those with sensitivities or evening workouts.

A bulkier package compared to the compact GU Energy Original Gels 8-count box makes it less ideal for tossing into a tiny race-day pouch. For runners who know they want a caffeine kick, you’d look to a caffeinated Maurten gel instead. But as a foundational, stomach-friendly fuel to test the waters, this variety pack does the job without overcomplicating things.
