Science in Sport launches full Beta Fuel endurance range

15 Jul 2021

Beta Fuel powder, gels and chews debut a 1:0.8 ratio of maltodextrin to fructose, maximising carbohydrate usage and minimising funny tummies

Science in Sport has launched a full range of Beta Fuel endurance nutrition products with a new 1:0.8 ratio of maltodextrin to fructose and claims it's 'the most complete and innovative fuelling solution on the market'.

The sports nutrition experts who work closely with Ineos Grenadiers previously had a Beta Fuel powder but have revamped that product and added gels and chew bars to the range designed for rides over two and a half hours.

SiS says the products have been tested not only in lab settings but also by Ineos's top men, with the team using them at the 2020 Tour de France as well as in Tao Geoghegan Hart and Egan Bernal's Giro d'Italia victories. Apparently the team have even nicknamed Beta Fuel 'grenade gels'.

Beta Fuel, alpha performance

The development made by the brand's scientists that Beta Fuel has at its heart is the use of a new maltodextrin to fructose ratio, changing from the traditional 2:1 to 1:0.8.

This adaptation means that a higher percentage of the carbohydrates ingested can actually be used by the body, as the new ratio increases the percentage of ingested carbohydrate that is oxidised from 62% to 74%.

That then means that the body can use up to 90g of carbohydrates per hour, unlocking an extra level from both the product and the rider.

On top of that, SiS claims that not a single participant in its testing of the Beta Fuel products reported symptoms of gastrointestinal distress, possibly aided by the lack of artificial sweeteners.

SiS director of performance solutions, Professor James Morton – who previously worked for Team Sky and Liverpool FC – explains the development, saying, 'One of the greatest challenges in any sport is to quickly, conveniently, and adequately fuel in the throes of competition.

'Our science but practical based solution – underpinned by an optimal ratio of maltodextrin and fructose – is the key to Beta Fuel.

'We have spent years researching and finessing the optimum carbohydrate delivery system to allow athletes to fuel their best performances. We are confident that our latest product range is the most sophisticated and complete on the market and is set to redefine the way athletes approach endurance sports.'

Home on the range

There are three types of Beta Fuel products: energy drink powder, gels and chew bars.

The powder is available in orange, red berry or strawberry and lime flavour, while the chews – which are a new easily digestible texture that can be split into three blocks – come in lemon and orange.

The standard Beta Fuel gels have strawberry and lime or orange flavour, however there are also Beta Fuel + Nootropics gels in apple or lemon and lime that SiS says also help to maintain peak cognitive function throughout long rides.

You can also buy a special Beta Fuel 750ml bottle if you fancy it too.
