Go Isotonic vs Beta Fuel Gels

Which Science in Sport gel is right for me, GO Isotonic or the Beta Fuel?  

Both deliver you the energy you’re going to need for any endurance sport, but there are some slight differences between the two. Putting these two powerhouse endurance nutrition gels side by side should help you to find out which one is right for you.  

 

The amount of carbohydrates in a SiS gel? 

The GO Isotonic packs 22g of carbohydrates into a single unit, whereas the Beta Fuel offers you more with 40g in each gel. Not only does Beta Fuel have a higher level of carbohydrate but it is also derived from dual sources, with a ratio of 1:0.8, which enhances your power output and increases your body’s carbohydrate usage efficiency. Meaning you get more energy out of a single unit.  

Next up we have flavours, now this won’t impact your energy but if you like to switch up your flavours during an activity then the GO Isotonic comes out on top, with up to 10 different flavours to choose from. The Beta Fuel still has 2 delicious options, but if you are out for a longer event this might be something to bear in mind.  

 

Endorsed by elite athletes 

Both the GO isotonic and Beta Fuel are favourites with our elites, with Olympic Marathoners like Steph Davis and Mo El Aaraby are fans of the GO Isotonic range, the same as Tottenham Hotspur players Lucas Moura and Eric Dier. Beta Fuel has become a firm favourite within the INEOS Grenadiers team as well as triathlon legend Tim Don.   

 

Here is a quickfire breakdown between the GO Isotonic Energy Gel and a Beta Fuel Energy Gel. 

 

  Beta Fuel  GO Isotonic  
Carbohydrate amount  40g  22g 
Informed-Sport Tested  Yes   Yes  
Vegan   Yes   Yes  
Choice of flavours  2  10 
Dual source energy  Yes  No 
GI distress  Minimal  Minimal 

 

The original vs the latest innovation

The GO Isotonic is the World’s first Isotonic energy gel, and chances are you might have come across one, it’s the OG of endurance nutrition and as the adage goes, if it’s not broken, don’t fix it! Being an Isotonic gel, this means you won’t need any additional liquid when taking the product, the mixture has the correct balance of water/ carbohydrate and electrolytes.  

Whereas the Beta Fuel range and gels in particular are the newer kids on the block. Something you may not have come across before, they were created to help endurance athletes get even more out of themselves during events. The delivery and make-up of the Beta Fuel gels were a revelation when they were released, immediately impacting performances like Chris Froome’s legendary solo breakaway on Stage 19 of the 2018 Giro d’Italia.  

 

Here are some of our FAQs and recommendations on Beta Fuel vs GO Isotonic; 

Q – Which is better for longer endurance events?  

A – Beta Fuel. It was optimised and created specifically for activities over 2 hours.  

 

Q – Which is better for beginners, I’ve never had a gel before?  

A – The GO Isotonic gel is a thinner viscosity and easier product to get used to when first trying an energy gel. 

 

Q – I want to PB and go all out, which should I use? 

A – Beta Fuel is great for higher intensities to top up your energy stores from a dual source. 

 

Q – I do not have much space to carry gels, which are smaller?  

A – The Beta Fuel is a smaller packaging size, so you’ll be able to fit more in. 

 

By now you should have an idea of which SiS energy gel is right for you. A lot of the time, you can get the best results if you switch up your fuelling choices between different energy gels, bars, drinks and chews. But if you solely looking to use gels then hopefully this comparison between the Beta Fuel Gels and GO Isotonic gels has helped.
