1. GU Energy Original

These little gel packets are tops, and they come in a rather huge array of flavors (including some unusual novelty ones), so everyone should find something to suit them.

With 100 calories per gel, it’s the perfect pick-me-up when you need a boost. You won’t find anything dodgy on the ingredient list – it’s vegan, gluten-free, and kosher so absolutely everybody can partake healthily.

Each gel is loaded with complex, easy-to-digest carbs, amino acids to aid in muscle recovery, and electrolytes to replenish what you lose on the road.

You’ll need to double-check the flavor you’re buying as some are caffeinated and others aren’t.

Customers have also scored this gel high for being easy to open and eat but not so flimsy that it breaks or tears open while still in a pocket.

Be aware that some runners may not like the texture, and, as with all supplements, some may have a less than desirable digestive reaction. We advise testing these before you hit the race, so you aren’t caught unaware!


  • Multitude of flavors available
  • 100 calories, 2 – 23 grams carbs per gel
  • Contain complex carbs, electrolytes, and amino acids
  • Some are caffeinated some aren’t


  • Some runners may not like the texture

Best for Marathon Training

2. GU Energy Roctane

As you can tell by the name, these gels are similar to our top choice. The difference is that these ones are created more with long distances and higher intensity in mind.

They’re also available in a large range of flavors and come in caffeinated and non-caffeinated versions.

While they contain roughly the same amount of carbs as our top choice, they’re much denser in both amino acids and sodium. Each serving of these will give you a much-needed electrolyte kick!

For endurance athletes, these will help boost that stamina when you need it!


  • 125 – 180 milligrams sodium per serving
  • 1425 milligrams of amino acids each
  • Available with or without caffeine
  • Made for endurance races


  • Some of the flavors are sickly sweet

Top Organic and Gluten-Free

3. Honey Stinger Energy Gels

If you’re careful about what you ingest and that extends to running nutrition, we’ve chosen these as our top organic, gluten-free gels.

They’re honey-based, which immediately makes them a healthy option with antibiotic properties. There’s no artificial flavoring in these gels – everything is 100% natural, and they’re certified gluten-free and USDA organic.

Honey is also easy to digest and is actually usually very easy on the stomach. Some may find it quite sweet, but no matter how you feel about the taste it’s best chased by a couple of sips of water to aid in digestion.

We like that you can use these gels in a variety of ways when you’re not running. Mix them into hot water for a soothing tea, cold water for a sweet energy-boosting drink, or spread them on bread like regular honey!

Each packet contains 100 calories, and be aware that some contain caffeine and others don’t!


  • Naturally flavored
  • Certified gluten-free and USDA organic
  • Honey-based for quick absorption and easy digestion
  • Variety of ways to use it


  • The packaging is thick, so can be a little difficult to open while running

Best Value Energy Gel

4. CLIF SHOT Energy Gel

We’re always on the lookout for products that deliver high value for a wallet-friendly price, and this one wins that spot when it comes to gels.

They’re available in some delicious-sounding flavors so pick your favorite dessert and try it out!

You’ll find that some of them contain caffeine, and others don’t. Check carefully, though, as the caffeinated ones come in varying strengths.

They’re also packed with electrolytes, including the essential sodium, potassium, and magnesium.

As an added bonus, these gels are the most environmentally-friendly ones we’ve come across. The company makes every effort to only use renewable energy sources, sustainable organic ingredients, pack their products in environmentally-friendly packaging, and even goes so far as to transport their goods in non-polluting vehicles!


  • Promotes sustainability
  • Caffeinated and caffeine-free flavors
  • Electrolyte-filled
  • Easy on the digestive system


  • Some users report them being a little too sticky to take comfortably

Best Isotonic – Consumable Without Water

5. Science in Sport GO Isotonic Energy Gels

Most gels need to be consumed with water in order to kickstart the digestion process and get them digested as quickly as possible. If you’re looking for something that doesn’t need that extra water, then you’re in luck.

It’s also of a thinner consistency than most others, so it goes down easily. With 22 grams of carbs in each sachet, you’ll get a nice bit of energy after taking one.

Each of the many flavors are created to be light and subtle, so there should be no overpowering sickly sweetness.

These gels are certified to be free of prohibited substances and packed full of only good stuff by the Informed Sport Evolved Certification program.

One potential downside is that these gels seem to burst at the seams easier than others. Be careful if you’re going to be carrying them in a tight space!


  • No water necessary
  • Thinner consistency than most
  • 22 grams of carbohydrates
  • Certified by the Informed Sport Evolved Certification program


  • Multiple customers have reported that the packets burst easily at the seams in a bag or belt

Top All-Natural

6. Huma Plus Energy Gels

Not all gels are all-natural. Many contain artificial ingredients, although they’re mostly all designed to serve a helpful purpose.

This one, though, is all-natural and made with real food ingredients. There’s no artificial flavoring in these – just real fruit.

As well as healthy carbs, you’ll find a stack of electrolytes in each sachet, to refresh you when you need them on the road.

They’re not only all-natural, but they’re also gluten-free and vegan. Some flavors have a dash of caffeine in them, also from natural sources.


  • All-natural, vegan, and gluten-free
  • Carbohydrates and electrolyte mix
  • Some contain caffeine
  • Flavored by real fruit


  • Chia seeds may get stuck in teeth!

Best Vegan Energy Gels

7. PowerBar PowerGel Original

Thankfully, vegan products are becoming more and more common. This is our choice for best vegan energy gels.

These gel sachets not only avoid any animal products, but they also have some unusual but effective ingredient blends.

Their C2MAZ Dual Carb Source mix provides a nice 25 grams of easy-to-digest carbs from healthy sources. Another thing we like is that these gels have a 2:1 glucose/fructose ratio, which helps the sugars get absorbed more readily and adds an extra little spark to your energy and muscle recovery.

They’re formulated a little differently to others, which scores them extra points in both the innovative and effective categories.


  • Easy-open packaging
  • Multiple flavors to suit every person
  • 25g C2MAX Dual Source Carb Mix
  • 2:1 ratio of glucose and fructose


  • The packaging may split too easily inside bags or pockets

Top Waste-Reducing Bulk Pouch

8. GU Original 15-Serving Pouch

Sometimes, small sachets can break, leak, or expire too quickly and leave you having to throw them away. This 15-serving pouch is designed to prevent waste and to avoid having to throw away single servings.

You can choose from an array of flavors, some with caffeine and some without. They all contain branched-chain amino acids, which are helpful for muscle recovery, as well as electrolytes sodium and potassium.

If you’re using a caffeinated flavor, using the same flavor 4 or 5 times during one race may be overdoing it on the caffeine a little. The only way to counter this would be to carry more pouches, either a large one like this or a couple of smaller single servings.


  • 15 servings in one package
  • 125mg Sodium, 40mg Potassium per serving
  • Contain BCAAs for better recovery
  • Available with or without caffeine


  • Can’t alternate between caffeinated/non-caffeinated

Those runners who struggle with low blood sugar, having a few of these in your pocket could be a lifesaver.

Packing a glucose punch of 15 grams, these quick-open, quick-eat pouches will do a good job of getting your blood sugar levels up in no time.

They’re small enough to carry a good few with you at any given time. They’re super for any situation, too – not just running!

Unfortunately, there seems to be only one flavor available, but when you need sugar now, you may not be fussy about how it tastes!


  • Great for diabetics
  • 15 grams of glucose
  • Space-saving
  • Easy to open

Top Caffeine Energy Gel

10. Hammer Nutrition Hammer Gel Espresso

For some of us, a caffeine-packed gel is just a step closer to an upset stomach. But for others, a caffeine boost is like a mini turbo-charger and can have a significant impact on their performance!

If you’re one of the latter, you may like these gels. Not all flavors contain caffeine, so runners of all preferences can use these.

Those that do contain the good stuff, though, contain a nice amount. Espresso flavor packs a punch of 50mg, while Tropical contains half that.


  • All-natural ingredients
  • Contain caffeine-free flavors too
  • Complex carbohydrate blend
  • Flavored and carbed-up by real fruit


  • May not be enough flavor variation for caffeine fans

Are you unsure about whether or not energy gels could be helpful for you? Here are some of the most asked questions so you can learn more about them and decide if they’re right for you!

Why Do I Need Energy Gels?

Carbohydrates are the body’s main source of fuel. When you run, your body burns carbs to fuel you along your run!

Once those easily available carbs are depleted, your body uses what’s stored in your muscles for fuel (known as glycogen). But once you’ve hit the halfway point on your half-marathon or marathon, you’re likely to be running quite low on glycogen!

Energy gels are a quick-absorbing form of carbohydrates that refuel your body and give you a boost. Because they’re in a very concentrated form, they get to work very quickly and effectively.

What Is Usually In Energy Gels?

An energy gel will usually have around 25 grams of carbs in it. Sometimes, that’s all they need, but many of them include other useful ingredients to enhance your performance.

Some include electrolytes to replenish you on the go. Others may contain caffeine to help with blood flow and oxygenation. Most use natural flavors, often fruit, which also add a dash of antioxidants.

How Long Will It Take to Absorb?

Gels can absorb in as little as 3 minutes, or they can take a little longer, up to 15 minutes.

It really depends on the type of gel you’re taking. Another factor that can make a difference is how depleted you are. In order for easy digestion and absorption to take place, there still needs to be blood going towards the stomach.

Most of your blood will be in your muscles when you’re late in a run, and won’t be expended on things like digestion in that moment. Therefore, it’s essential to take a gel before you hit a low point and feel like you can’t go anymore.

How Often Should I Take a Gel?

For the average 20 – 25 grams of carbs per gel, you should take one every 45 minutes to an hour. For example, if you’re running a 5-hour marathon, this means you’d need at least 5 gels in your pack for the race.

It’s a good idea to alternate between gels containing caffeine and those without caffeine. Too much caffeine can have a detrimental effect, on both your stomach and your running performance.

If you can, stick to this timing. Waiting until you already feel pooped is too late!

What Else is Important to Know About Gels?

Pro tip! Don’t go into a marathon having never used gels before. Use them while training first so you can get an idea of how they affect you and how your body deals with them. The same goes for if you’re trying a new brand!

Always take your gel with plain water. Don’t mix them with sports drinks – that could be an overload of sugar.
