If you need a hit of energy to get you through a long, hard workout, your best bet is to grab an energy drink, gel, chew or bar.
‘The body uses carbohydrates (which are stored in the muscles as glycogen) as its preferred fuel source during exercise,’ explains David Wiener, training and nutrition specialist at fitness app Freeletics. ‘It’s around the 90-minute mark that carb stores become depleted, and the body turns to its fat supply to fuel movement instead.’
While burning fat may sound like a good thing, fat stores don’t release as much energy at the same rate, says Wiener. When you’re outta carbs, you’re likely to hit the proverbial wall, and your performance will suffer.
The best energy drinks, gels and chews are made up of easy-to-digest carbs. They’re designed to enter your system and fire you up stat, allowing you to finish your endurance activity pumped full of endorphins.
Which Supplements Give You The Most Energy?
Energy products are primarily made up of simple sugar – often a combination of maltodextrin and fructose – for quick absorption. Many also contain electrolytes (such as sodium and potassium) to help replace the minerals lost through sweat, and some offer a kick of caffeine.
‘Be mindful of caffeine as it doesn’t suit everyone,’ warns Wiener. ‘Some people find it makes them dehydrate faster or need to use the toilet more, which is not what you want if you’re taking on a big race or event.’
Energy Drinks, Gels, Chews Or Bars?
So, which should you try? Yet again, it boils down to personal preference, but here’s a rough guide.
Energy drinks: Ideal during the summer months for topping up your carbs while hydrating your body on the go. Lugging a bottle around a long course can be a hassle, though.
Energy gels: Popular with runners, the best energy gels slip into your pocket for easy consumption during exercise. They can be a little messy but get easier to use with practice.
Energy chews: Often resembling a gummy sweet, these bad boys can feel gentler and more satisfying to consume for those with sensitive stomachs. That said, if you’re exercising at a high intensity, chewing can be tricky and affect your rhythm.
With both gels and chews, it’s important to drink enough water to help your body digest it properly and ensure you stay hydrated.
Energy bars: A top choice if you prefer solids to liquids and want something more substantial to keep you going during an endurance activity.
How To Use Energy Supplements
Generally, Wiener recommends consuming 1g of carbs per kilo of bodyweight every 60 minutes. So, if you weigh 80kg, aim for 80g of carbs per hour of exercise.
‘There is a limit to how many carbohydrates your body can absorb, so I wouldn’t recommend taking more than two gels or two drinks in an hour,’ he says ‘They’d just end up filling your stomach and you wouldn’t reap any benefits.’
Because there’s such a plethora of energy products available, try a few and see how they sit with you. ‘Once you find something you like, I’d suggest training with it consistently,’ recommends Wiener. ‘This will help your body adapt to its usage and lessen the risk of digestive issues at critical moments.’
How We Test
As part of our 2024 and 2025 Sports Nutrition Awards, we enlisted the help of four leading sports nutritionists – Rob Hobson, Tai Ibitoye, Lee Amico and Dr Sinead Roberts – to evaluate a range of energy drinks, gels, chews and bars.
They judged each product based on the quality of their ingredients (they had to be easily digestible to avoid any stomach issues mid-workout), their nutritional make-up and formulation in line with its intended use. Only the supps that really impressed our experts were put forward for further testing.
Back at MH HQ, our in-house panel of editors and food testers then rated each contender on flavour, texture and ease of use when it came to accessible packaging, mixing and refuelling during exercise.
With energy gels, there was an additional layer of testing – our pros trialled them over a period of a few weeks to see how they impacted athletic performance. Once all testing was complete, feedback and ratings were analysed, and final scores were awarded.
The high-carb heroes stamped with the Sports Nutrition Awards badge below were our panel’s runaway favourites.

Best energy drink for focus
C4 Performance Energy: Millions Bubblegum (12 Cans)
Per 330ml can: 15kcal, 106mg caffeine
This is an energy drink with a difference. Alongside 106mg of natural caffeine, it contains nootropics, aka ‘smart drugs’, and Brainberry® (Aronia berry extract), which have been linked to improvements in cognitive performance.
Each can also delivers a dose of fatigue-fighting, recovery-promoting ingredients including vitamins C, B5 and zinc. Plus, it’s zero sugar, free from artificial sweeteners and has a negligible calorie count. The bubblegum flavour was popular among our panel, as was the gently fizzy consistency. For something a little bit different, give C4’s smart bev a go.

Best for natural ingredients
Tenzing Natural Energy Drink Fiery Mango (12 Cans)
Per 330ml can: 63kcal, 14.9g carbs, 106mg caffeine
Jonesing for a natural boost? Tenzing will keep your fire burning with the help of 106g of caffeine from green tea and green coffee, combined with beet sugar, fruit juices and Himalayan rock salt. The sparkling blend also contains 1500mg of BCAAs to help with mental fatigue and muscle recovery.
Testers approved of the level of carbonation (which wasn’t too fizzy) and enjoyed the mango flavour. Additionally, the brand claims it’s the world’s first carbon-negative energy drink, so you can get your pump on knowing you’re doing your bit for the planet.

Best on the go
Science in Sport Beta Fuel 80: Orange
Per 82g serving: 320kcal, 80g carbs, 45g sugar
Endurance fiends, this one’s for you. It packs 80g of carbs per serving, so you only need to slip a few sachets in your pocket to reap the energy-boosting rewards. While most energy supplements provide a 3:1 glucose to fructose ratio, this one has a 1:0.8 blend of maltodextrin and fructose.
According to SiS, this allows your body to absorb more carbs per hour without upsetting your stomach. Our panel rated the smooth consistency and natural orange flavour, which will slip down easily during exercise.

Best for flavour
NOCCO Carbonated Caffeine Drink: Caribbean
Per 330ml can: 12kcal, 0g carbs, 180mg caffeine
Nocco is best described as a carbonated caffeine drink and boy, does it taste good. The Caribbean flavour is much like a piña colada, minus the rum and the buckets of sugar (it contains a big fat 0g of the sweet stuff). Instead, you get 180mg of caffeine to fire up your session, along with 3000mg of BCAAs and 50% of your daily vitamin B6 and B12 intake.
A few panellists thought the fizzy consistency would be difficult to gulp mid-workout, but they would happily drink it en route to the gym. For those looking to avoid any jitters, there’s a caffeine-free version, plus a host of fun flavours to try including mango, melba and summer strawberry.

Best for gym sessions
Red Bull: The Apricot-Strawberry Edition
Cons
Per 250ml can: 113kcal, 27g carbs, 80mg caffeine
If you’re partial to a Red Bull, you’ll love this fruity apricot and strawberry version. Our testers couldn’t get enough of its sweet juicy flavour, saying it reminded them of old-school pick ‘n’ mix sweets. Their only gripe was the bubbles – they would have preferred something less fizzy to down mid-session.
Aside from 80mg of caffeine (equivalent to a single espresso shot), it contains sugar, water and taurine, an amino acid that’s linked to reduced muscle fatigue and enhanced energy. It won’t up your carbs like some of the gels listed here, so reach for a can when you’re flagging in the gym as opposed to on a lengthy run or bike ride.
We’re also huge fans of the brand’s exciting new curuba and elderflower Summer Edition, which is fruity, refreshing and delicious.

Best energy drink with nootropics
Protein Works Endless Nootropic: Sour Cherry Bomb
Per 10g serving: 12kcal, 3g carbs, 150mg caffeine
As the name suggests, this Protein Works powder is packed with nootropics – so-called smart drugs that aim to enhance cognitive function. It also contains an optimal 2:1 ratio of L-Theanine to caffeine to give you a steady surge of energy without causing a caffeine crash, along with a host of B vitamins including B6, B12 and B9 to combat fatigue and improve attention.
Unlike the other options in this round-up, it comes in powder form – just mix it with cold water in your protein shaker and you’re good to go. It dissolved well, with no powdery residue, and our panel enjoyed the strong cherry flavour, but be warned, it’s extremely sweet and tastes a tad artificial.

Best energy gel
Maurten Gel 100
Per 40g serving: 100kcal, 25g carbs, 25g sugar, 50mg salt
If, like us, you find super-sweet gels a little overwhelming, you’ll appreciate the neutral flavour of this one. The thick consistency also means you’ll avoid a mid-race mess. Each sachet contains simple ingredients – water, sugars and minerals – with no unnecessary chemicals. Plus, if it’s good enough for Sir Mo Farah…

Veloforte Mela Energy Chews: Apple & Cinnamon
Per 50g pack: 179kcal, 44.4g carbs, 38.3g sugar, 30mg salt
For those who prefer to take on solids, Veloforte’s packs of gummy sweets, which provide over 44g of carbs and a small bump of electrolytes to keep you hydrated, are a smart choice.
They have a subtle fruity flavour and melt-in-your-mouth texture (reminding our panel of Turkish Delight), which makes them easy to gobble on the go. Like Maturen, they’re also made with natural ingredients – including fruit juices, beetroot sugar, cinnamon, coconut water and pink Himalayan salt – so they’re ideal for those with GI woes.

Best for tired days
Science in Sport Beta Fuel + Nootropics: Lemon & Lime
Alongside 40g of carbs and 200mg caffeine for a mighty stamina boost, this gel is fortified with nootropic ingredients – including taurine, theanine and citicoline – to help fight mental fatigue midway through a race.
Research into nootropics is still in its infancy, but the gel also boasts a 1:0.8 blend of maltodextrin and fructose to avoid digestive dramas, it tears open easily, and has a smooth consistency, making it a clever choice, regardless.

Best gel for ease of use
Veloforte Desto Gel: Tart Cherry & Guarana
Per 33g serving: 89kcal, 22g carbs, 16.8g sugar, 0.3g salt
This all-natural energy gel, made from real fruit juices and plant syrups, provides a respectable 22g of carbs per serving, along with 75mg of natural caffeine from guarana extract, and a healthy dose of electrolytes (110mg of sodium from pink Himalayan salt) to keep you hydrated and supercharge your sessions.
Our testers liked the sour cherry flavour, which wasn’t overwhelming, and found the loose gel-like texture easy to chug during high-intensity exercise.
It also earned praise for its packaging – our testers found it simple to open and its petite size meant it didn’t feel bulky in their pockets. No digestive issues were reported, and everyone confirmed they felt a boost from the caffeine. Tick, tick.

Best sweet treat
STYRKR BAR50: Date, Almond & Sea Salt
Per 65g bar: 257kcal, 1.7g protein, 50.4g carbs, 5.3g fat
Our nutritionists were impressed with this plant-based entry. Unlike most energy bars that are oat or wheat based, it uses rice flour, which is easier on the stomach.
It’s also low in fibre and protein, which typically take a while to digest, so it won’t slow you down during your chosen activity. Instead, it goes go big on carbs and sugar to keep your fuel levels up. Best of all, it’s genuinely delicious; a bit like a chewy, chocolate rice crispy cake.

Best for snacking on the go
Science In Sport Go Energy Bake: Lemon
Per 50g bar: 190kcal, 3.5g protein, 30g carbs, 5g fat
If you can’t stomach gels or drinks but could do with a mid-run boost to replenish your carbs, let us introduce you to this petite bar, which can be easily slipped into your pocket or running vest.
The soft bake, complete with an oozing, zingy centre, tastes like a cake bar and doesn’t require lots of chomping. Crucially, it’s packed with 30g of carbs and 10g of fructose to maximise your performance. Like all SiS products, it’s suitable for drug-tested athletes.
13
Best for recyclable packaging
33Fuel Amore Natural Energy Bar: Original
Per 60g bar: 227kcal, 37g carbs, 7g fat
Another energy bar with a focus on natural ingredients, this plant-based snack is loaded with whopping great chunks of almonds, dried fruits, candied peels, cinnamon, maca and coconut sugar. That’s it. Our panel likened it to traditional fruit cake, thanks to its dense texture and spiced flavour.
As it provides slow-release energy from low GI complex carbs, our nutritionists thought it was best suited to long hikes, cross-country runs or mountain biking. Stick one in your pocket on your next adventure and it’ll keep you fuelled for hours.
Even better? 33Fuel’s packaging is fully recyclable, available with carbon-neutral delivery and a portion of all sales go to One Tree Planted to support their global reforestation efforts. Excellent stuff.

Best natural boost
Hammer Nutrition Raw Energy Bar: Almond Raisin
Per 50g bar: 220kcal, 10g protein, 25g carbs, 9g fat
Offering a shot of motivation without a long list of unpronounceable ingredients, this vegan bar is made from almond butter, date paste, agave, rice protein, sprouts, seeds and raisins, all of which are organic.
The soft, gooey texture earned high praise from our panel, who thought it would be great for munching on hikes, bike rides and even runs. The natural fruit and nut taste was also a big hit.
