This composition has been extensively tested and proven to fuel very high energy rates with very low potential for gastrointestinal distress.

Each energy gel also contains mg of sodium to help with fluid delivery and retention. Neversecond Energy Gels, as with all of our C-Series range of fueling products , are the result of working with and listening to top global endurance athletes and teams over a year span.

All of the critical product details - the carbohydrate content and composition, the sodium and caffeine level and liquid-like texture - have all been carefully considered in conjunction with the most current scientific research coupled with real world athlete input.

C30 Energy Gels are also isotonic energy gels, so they absorb more easily and deliver energy more quickly and efficiently than traditional sports gels. Although energy gels have been used in endurance sports for the past 25 years, their use as a performance tool has exploded in the last 5 years as athletes have come to realize that well-fueled athletes simply perform better and more consistently.

Many top World Tour riders and triathletes consume as much as grams of carbohydrate per hour on the bike via sports gels.

Runners, historically a bit more hesitant due to the inherent jostling motion associated with running, are also starting to realize the benefits of using running gels to help fuel their performances. With proper gut training, carbohydrate intake can also be optimized to help athletes with the most sensitive stomachs achieve peak performance.

The portability of energy gel packs as lightweight, portable fuel makes C30 Energy Gels ideal for both road and trail runners.

Unlike other sports gels which use arbitrary nutrient values, C30 Energy Gels are developed as a critical part of our modular C-Series system of products. C30 Energy Gels can be combined with any of our fuel and hydration drink mixes and energy bars to provide a personalized solution that addresses both athlete preferencs and practicality.

C30 Energy Gels are a glucose-to-fructose energy gel. They deliver 30g of fast-absorbing energy with a lower risk of stomach problems when compared with other gels. You can take C30 Energy Gels with or without water. They are also not sickly sweet like most other electrolyte gels on the market.

C30 Energy Gels use maltodextrin-to-fructose as the carbohydrate source. This delivers energy very efficiently with a reduced risk of gastrointestinal problems when compared with other energy and sports gels.

Our gels are an electrolyte energy gel. Sodium is the most critical electrolyte needed by endurance athletes. Sodium helps deliver and retain fluid and is lost through sweat, so replacing sodium is critical to maintaining hydration and performing optimally. C30 gel packs are larger than others as they are an isotonic energy gel.

Unlike traditional thick gels, Our gels can be taken with or without water. Isotonic energy gels absorb more efficiently than traditional gels and are less likely to cause stomach problems. C30 Energy Gels also have a higher carbohydrate content 30 grams per gel than most other sports gels.

Our gels are as natural as any other energy gels. That is to say - all energy and sports gels are highly processed food supplements. The processing allows them to absorb easily, which is a good thing when you need fast energy without the consequence of gastrointestinal problems.

How many Neversecond Energy Gels you need depends on the duration and intensity of your activity. The shorter the duration and lower your intensity, the less carbohydrate you need per hour and per session.

The longer the activity and harder your intensity, the more carbohydrate you need per hour and per session. You can easily determine your carb intake for any session or race using our Neversecond Guidance System.

Simply enter a few details about your session or race, and you will receive an accurate science-based fueling recommendation. There should not be any side-effects associated with consumption of C30 Energy Gels with normal use.

There is a mix of simple and complex carbohydrates for quick and long-lasting energy during all your workouts.

These are available in fewer flavors than the original GU energy gels, but like the gels, there are both caffeinated and caffeine-free flavors. These have very positive customer reviews. GU Liquid Energy Packets are a good option for beginners who still need some practice getting gels down out on the course.

They are by far the easiest to get down mid-run. I tried the Cola and Lemonade flavors and loved both. I recommend refrigerating them for an even better taste. You can also freeze them for a slushy texture. They contain sea salt for flavor and hydration, boosting the sodium content to a very respectable milligrams per serving.

The downside is that the packet itself is quite large compared to other gels. On the bike, I can stuff one into my cycling jersey pocket but it takes more effort to get out while in motion than a smaller package.

Honey Stinger Energy Gels feature organic honey and electrolytes to provide energy throughout your workout. According to Honey Stinger, these gels are easy to digest and help to delay muscle fatigue.

They recommend consuming it during or before activity; you can eat it right out of the packet, mix it in tea, or spread it on toast. Honey Stinger Original Organic Energy Gel is the same as the Honey Stinger Caffeinated Energy Gel described above.

The only difference is the lack of caffeine. The first two ingredients are organic tapioca syrup and organic honey, which serve dual purposes as the carb sources and for taste. Potassium citrate and salt provide electrolytes, and citric acid, water, and organic natural flavorings make up the rest of the gel.

These organic gels are available in a few flavors, including Fruit Smoothie, Gold honey flavored , and Acai Pomegranate. The Strawberry Kiwi flavor is only available in the caffeinated version. I personally favor the Fruit Smoothie flavor, which has notes of strawberry, cherry, and orange.

The texture is liquidy enough to be refrigerated without getting too thick or syrupy, and these taste great cold. RELATED: Best Long-Distance Running Shoes. UnTapped provides pure Vermont maple syrup—based energy gels. These gels use minimal ingredients and are available in 5 maple syrup based flavors.

UnTapped shares that provide all-natural energy during your workouts. There are limited customer reviews, but they are mostly positive. Untapped Athletic Fuel gels are made entirely of natural ingredients—er, a single natural ingredient, actually.

This is straight maple syrup in a tear-to-open packet. Heads up: You will NOT like these if you do not like maple syrup. You can use them for your long runs and then pour one on your toaster waffles when you get back. Bomb, 4 out of 5 stars.

Maple syrup contains more naturally occurring nutrients than lab-created gels, which is not necessarily a performance factor, but is a nice touch. Each gram packet contains magnesium, zinc, thiamin, riboflavin, and manganese in addition to the normal inclusions of sodium, calcium, and potassium.

If you plan to use maple syrup as your only gel during training or racing, please also have a sports drink with sodium or salt tablets handy. In some of the other flavors—Salted Raspberry, Salted Cocoa, Salted Citrus—there is 60 to milligrams of sodium, which is much better.

RELATED: Best Running Shoes. Boom Nutrition Carb Boom Energy Gels use real fruit purees and concentrates without any artificial flavors, colors, or sweeteners to provide a steady source of energy during your longer workouts.

Boom Nutrition shares that their ratio of complex carbs to simple sugars helps to provide energy throughout your workout. There are very limited reviews, but they are extremely positive. There are only 6 flavors available and no caffeinated flavors. The gist here is similar to that of the maple syrup gels: If you like applesauce, add to cart.

I do like applesauce so I am pleased with Carb Boom! Apple Cinnamon Energy Gels. The texture is smooth and a little sticky, but in a good way, like apple pie filling.

These contain an interesting 9-to-1 ratio of maltodextrin to fructose with 26 total grams of carbohydrates and 3 grams of sugar. This could be really beneficial for people who tend to struggle digestively—such as with nausea or gut rumbling—when they consume too much sugar.

Carb Boom! Apple Cinnamon gels are made with real apple puree and apple concentrate, which is what makes the apple flavor come through so well. There are no artificial flavors, colors, or sweeteners, and all of the flavor options are gluten-free.

RELATED: How to Choose Running Shoes. Huma Chia Energy Gels provide energy for your workouts by using real food. Huma combines fruit puree, powdered chia seeds, and brown rice syrup to make an all-natural energy gel.

Huma shares that since their gels are real food, they are easy on the stomach and use a ratio or short -and long-chain glucose and fructose to maximize carbohydrate uptake. Customer reviews for this product are mostly positive, but there are some mixed reviews on taste. All Huma gels are vegan, gluten-free, and made with real fruit purees.

They do contain a nice milligrams of sodium, which is more than some lab-created gels. Recreational athletes who are just trying not to bonk during a long session should do just fine with Huma gels.

Those trying to smash personal records or training to be competitive athletes might want to go with something more dialed-in for performance benefits, like Maurten Gel or GU Roctane. My friend and teammate Laura said the taste is too sweet for her, but really liked the puree-style consistency and that these felt easy on her stomach.

Plus, the fruit flavors are sure to be refreshing on a hot trail day. Science in Sport SIS provides a combination of carbohydrates and electrolytes to fuel your longer workouts. SIS states that these gels help you maintain hydration during long or hot exercise sessions. There are limited reviews for this product, but they are mostly positive.

Science In Sport gels are isotonic gels. An isotonic solution is one that has the same osmotic pressure as another solution.

Osmotic pressure 10 has a complex definition, but in simple terms, it can be described as the minimum pressure needed to stop the flow of water through a membrane—or osmosis , if you remember that from high school biology.

In this case, the gels are the isotonic solution and your body cells are the other solution. So Science In Sport gels are designed to have the same osmotic pressure as the cells in your body. This means that they should not alter the fluid balance of your cells, thus maintaining ideal fluid balance—and thus hydration—during exercise.

What this means practically is that you should be able to consume Science in Sport gels without the usual need for simultaneous water consumption.

See our full guide to hydration for runners for more information. In addition to the isotonic formula that helps with hydration, these gels contain an electrolyte blend that is milligrams in total and contains sodium chloride, sodium citrate, potassium chloride, and magnesium citrate.

In total, there are milligrams of sodium, 9. I like the Salted Strawberry flavor best of the three available. The texture is thin and runny, so these are quite easy to consume. Unfortunately, CLIF discontinued them as of May 1, You can still get them while supplies last.

They taste OK and might be good for hikers. I personally chose all of the running gels on this list after buying them and using them during various training sessions and races, including a sprint triathlon and an Olympic triathlon. I took various gels with me on long runs, training rides, and even on a couple of hikes when I briefly escaped my ultra-flat home terrain of Florida.

To determine the best running gels, I noted factors like taste, texture, ease of consumption, packaging i. I also took note of how I felt during the training sessions, keeping in mind that performance is dictated by so many factors, including hydration, sleep, stress, weather, and more.

I enlisted some friends to help, too. One member of my triathlon team tried several of the gels during training; another friend used them to fuel during an mile ruck competition.

Running gels support endurance exercise by maintaining blood glucose levels and sparing glycogen stores. This is primarily because the muscular stores of fatty acids and glucose begin to run low over time.

Or, in this case, sugar. In this regard, it has been proposed that the brain is able to sense the diminished availability of glucose and brings about the termination of exercise as a protective mechanism. In short, running gels keep you going when your body is in need of fuel in the near-immediate future.

Some gels are sold as foods with a nutrition facts label and are still third-party tested, which is the best-case scenario. Athletes who are subject to drug testing should always choose supplements that are screened for banned substances. The most important thing to understand about running gels and how they work is that the human body is only capable of processing a finite amount of carbohydrate per hour.

According to the National Academy of Sports Medicine 3 , the body can process 60 grams of glucose and 30 grams of fructose per hour, so 90 grams of carbohydrates per hour in total.

People with sensitive stomachs may find that energy gels cause gastrointestinal problems, specifically nausea. Remember, your body can digest and process a maximum of 60 grams of glucose and 30 grams of fructose per hour 3.

Both energy gels and bars have their place. Many endurance athletes prefer gels because they come in very small packages and are easy to consume. Energy bars are more beneficial when taken at least an hour before training or racing, and they can be good replenishment afterward. The standard energy drink does not compare to energy gels in terms of endurance nutrition.

However, a sports drink that contains glucose, fructose, electrolytes, and, if desired, caffeine and amino acids, can work in place of gels. See the best sports drinks and best electrolyte drinks.

Bottom Line Maurten Gel provides energy for your workout with only six ingredients and without any additional colors, flavors, or preservatives. The texture of Maurten Gel is unlike that of any other gel I tried. It packs milligrams of caffeine about the same as an 8-ounce coffee , and our testers found the flavor to be slightly more palatable than others.

Each packet also provides calories and 24 grams of carbs. This Honey Stinger option is a go-to for an effective, tasty gel that also checks off the organic and gluten-free boxes.

Get the Deal! Yes, Spring Energy is incredibly expensive—more than double the cost of other brands. The vegan Canaberry option combines rice, banana, and strawberry with additional ingredients that add flavor and electrolytes.

For a milligram caffeine boost, try Speednut or Koffee , which was developed with two-time Olympian Kara Goucher. Our video producer and resident ultrarunner Pat Heine shells out for Spring Energy for his races, particularly the Canaberry and Awesome Sauce flavors.

This is basically a regular Gu gel on steroids. Designed for the ultra endurance athlete, the Roctane line has more electrolytes sodium and additional branched-chain amino acids leucine, valine, and isoleucine , which can help reduce mental fatigue and decrease muscle damage sustained over the long, long run.

Roctane also has the amino acid taurine famously found in Red Bull , which might help improve performance. Yes, syrup. Pure Vermont maple syrup. Syrup, as you might know, is straight-up quick-acting sugar like honey , making it a perfect choice to fuel long miles.

Our Runner-in-Chief and lead Test Editor Jeff Dengate has turned to UnTapped since the company first sent us samples more than five years ago. It makes a mean waffle , too. Each packet contains calories and 25 grams of sugar, plus small amounts of other nutrients, including zinc and manganese, which are naturally found in syrup.

Each package contains calories and 26 grams of sugar. A friend and former teammate knew the founder of the company, which was just starting to put out real-food, clean ingredients gels. The handmade, plant-based gels in this variety pack boast just four whole-food ingredients, which are plant-based, organic, and non-GMO.

But the gels are more expensive than most others on our list. Her work has been published in The Boston Globe, Popular Mechanics, The Wall Street Journal Buy Side, Forbes Vetted, Cooking Light, CNN, Glamour, The Associated Press, and Livestrong.
