High 5 Isogel Energy Gel 25 Pack

High 5 Isogel has been designed to be used without needing additional water, it tastes more like an energy drink whilst delivering the concentrated carbohydrate hit of an energy gel. Citrus flavour contains caffeine.

Manufacturer's Description

IsoGel has a consistency more like a sports drink than a gel. It is smooth and has a dash of real juice for a great taste. It’s not thick or overly sweet. Easy to open and swallow, each sachet contains 23g of carbohydrate. IsoGel is award-winning and proven in many of the World’s toughest competitions.

When taking IsoGel Plus (citrus flavour contains caffeine) as recommended, the caffeine content can increase attention, concentration and reaction time. IsoGel Plus is award-winning and proven in many of the World’s toughest competitions.

Which High5 gel to choose: EnergyGel or IsoGel? Both types of gel do the same job. However, IsoGel has a lighter consistency somewhere between a drink and a gel. EnergyGel has a slightly thicker consistency, but is less bulky and lighter in weight, which makes it easier to carry in larger quantities.

Press Reviews

Cycling Weekly

When: On the bike, for rides lasting more than two hours

Why: Its lighter consistency make it stand out from the rest. Whereas some gels can be rather thick and heavy on the stomach, IsoGel is more like a sports drink than a gel, making it easier to consume. It's refreshing, which makes a change from the chore-like feeling with more viscous gels. Each sachet contains 23g of carbohydrates.

High5 are known for their tasty sports nutrition and the IsoGel is no exception. Both the orange and berry flavours are refreshing rather than overpowering and neither get sickly even during longer races. This is probably aided by the gel’s thin consistency, which makes drinking it a cinch even if the sharp corners occasionally catch the inside of the mouth – though this is true of virtually every gel. As the name suggests, the IsoGel is isotonic, so doesn’t require generous slurping of water after consuming each gel. The downside is that you probably won’t be able to cram as many of the 60ml sachets into your nutrition box on the bike. Each gel provides 22g of carbohydrate and there’s also a citrus caffeine version for an extra kick when it’s really needed. Verdict - One of the tastiest and easiest ways to keep energy levels up.

High5 IsoGel is not really a gel at all. Despite the name, it's a liquid. So it's a carb-based sports drink in a gel-style sachet. Thus, it delivers energy and hydration - unlike normal gels where you need to take on liquid separately - but it's of questionable benefit for most road cyclists.

Each sachet of IsoGel is 60g. According to the packaging, each gel contains 26g of carbohydrate, providing 104 kcal of energy. According to the High5 website, each gel contains 22g of carb, providing 88 kcal.

Either way, the main ingredients include water, glucose and fruit juice. The texture is - as you might expect - just like watered-down fruit juice. The taste is not sweet at all, making this drink very pleasant and refreshing.

Isogels are also available in a 'Plus' version, where the standard ingredients are joined by 30mg of caffeine. According to High5 website this will 'enhance performance and improve carbohydrate uptake'.

I have tested several sachets of standard IsoGel and Isogel Plus on some long rides, and they definitely work, but I found them no better or worse than High5's other energy gels (reviewed elsewhere on road.cc) which contain a similar amount of carb - 20g - but without the additional 40g of water.

So while these Isogels might be a neat idea for runners, I don't think they're any more useful for cyclists than 'normal' gels - assuming you've got a bottle on your bike. In addition, the Isogels weigh more than a normal gel with the same amount of carb content, they're more bulky in your back pocket, and they're hard to consume on the go as the fluid escapes easily from the sachet.

Having said that, I suppose it might be useful to carry one or two Isogels in case your bottles run dry in the last 10 miles of a long sportive. Also, some riders may prefer the taste and consistency of Isogels compared to normal gels, but if you struggle with normal gels and want something more liquid, then you're probably better off just using a carb-based energy drink in a bottle.

Cycling Plus

Another of the new 'liquid gels' that can be taken without water. This one has added sea salt for that 'fresh from the ocean' taste. Verdict... Like a very thich drink. It's easy to get down and the taste is sweet without being too sickly. There's a slight sugary aftertaste.

British energy company High 5 has introduced a range of isotonic gels that can be taken without the addition of water. What's good here is that the gel tastes very much like a sports drink in that it's not too strong or over powering and very easy to get down. We have tried them for a few weeks now with no problems and they've become a staple before longer outdoor swim sessions.

Each 60ml sachet, which is a little bigger than some, delivers 24 grams of carbohydrates to help keep you fuelled. The gel is very thin in terms of viscosity and easily swallowed which makes taking them on the move a doddle. For those wanting a kick as well as an energy boost there's also a caffeinated version in citrus plus flavour.
