Product Overview
THE MOST SCIENTIFICALLY SUPERIOR ENERGY DRINK ON THE MARKET
Long been favoured by elite athletes, our famous Science in Sport Beta Fuel Energy Drink has now been optimised, making it a scientifically superior fuel. A brand new 1:0.8 ratio of 80g carbohydrate enhances your power output, increases your body's carbohydrate usage efficiency, and limits gastrointestinal discomfort.
WHY YOU SHOULD USE BETA FUEL DUAL SOURCE ENERGY DRINK
As an endurance athlete, meaning your events typically last more than two hours, you need to take in between 80-120g of carbohydrate per hour. The Science in Sport Beta Fuel Dual Source Energy Drink delivers an optimised 80g of carbohydrate in a single, convenient isotonic fuelling solution with minimal risk of GI discomfort that enables you to maintain optimal performance.
NEW 1:0.8 RATIO REPLACES 2:1 RATIO
- A 1:0.8 ratio of maltodextrin to fructose increases the percentage of ingested carbohydrate that is oxidized (known as efficiency) from 62% to 74% when compared with a ratio of 2:1
- A 1:0.8 ratio of maltodextrin to fructose reduces self-reported symptoms of stomach fullness when compared with a ratio of 2:1
THE SCIENCE BEHIND BETA FUEL HAS EVOLVED
Through our Performance Solutions team, we have worked closely with elite athletes in the research and development of the new Beta Fuel range to bring you a scientifically superior fuel in a range of formats that allow you to use +17% more carbohydrate (O’Brien et al, 2013).
- A ratio of 1:0.8 enhances exogenous CHO oxidation compared with 2:1 ratio by 17% (O’Brien et al) and 10% (O’Brien et al)
- A ratio of 1:0.8 enhances mean power output during 10 maximal sprint efforts by 3% compared with 2:1 ratio (O’Brien et al)
- A ratio of 1:0.8 increases % of ingested CHO that was oxidised (efficiency) from 62% (2:1) to 74% (1:0.8) (O’Brien et al)
- A ratio of 1:0.8 reduces symptoms of stomach fullness and nausea when compared with a ratio of 2:1 (O’Brien et al)
Suggested Use
One sachet of Beta Fuel Energy Drink contains one serving (82g) of powder. Tip the mix-and-go formula into 600ml of water and shake to dissolve. It's that simple.
- Sip little and often during prolonged endurance exercise.
- Use one powder sachet per hour or combine with Beta Fuel Gels or Chew Bar to hit hourly 80-120g carbohydrate intake.

Really is, "fuel". Going deep into the red on a climb or whatever activity. I just feel better for using this. The one downside; it's is hard work to mix in traditional "shaker" bottle! I've had to switch to using a blender and adding a little at a time to make sure it's all blended in. Possibly just my weak arms?

This was my first SIS purchase and it will be my last. I bought this product to use during long ride to keep me fueled. With only one flavour available on the website: strawberry and lime it was the only option. It's so sweet it is unpleasant to use and doesn't quench your thirst. What's more it's so sticky that your bottles and hands get covered in it. I ended up throwing it away and buying a bottle of water from a shop on the route. I'd advise avoiding it unless you have the taste buds of Willy Wonka or a six year old kid.

It's not cheap but it works (if you can be bothered you can make DIY beta fuel for a fraction of the price. Note that 80g in 500ml is like syrup. If you're a heavy sweater think about adding electrolytes. Strawberry & Lime definitely the best flavour to go for.

The only issue one should be aware of is the product doesn't mix well with cold water. At the moment, I mix with hot water beforehand and cool it down before the ride.

Having used many carbohydrate powders, SIS Beta Fuel is by far the best. Extremely palatable (red berry) and has fuelled me on some really challenging days in the saddle - long distances and big ascents.

Il prodotto ti mantiene alta la prestazione se bevuto a piccoli sorsi durante l’uscita in bici. L’unico difetto è che l’ho trovato un po’ troppo dolce.

Prodotto molto buono. 80g di carboidrati per busta. Sapore molto buono. Unica cosa non si scioglie immediatamente. Bisogna versarlo gradatamente e scuotere parecchio. A parte questo ottimo prodotto che uso insieme ai GEL

Il prodotto la prima volta non mi ha soddisfatto ma dalla seconda volta ho capito che andava sciolto meglio, dal quel momento è un prodotto top. Certo per allenamenti di poca intensità sono uno spreco.
