ADVANCED BY SCIENCE
Developed with elite athletes to meet the need for more carbohydrates. BETA FUEL uses two types of carbohydrate (maltodextrin and fructose) in an optimal 1:0.8 dual source formulation enhancing the amount of carbohydrate your body can use during exercise, highlighting the BETA Fuel Range as the most complete fuelling solution in endurance sport.
THE FUEL YOU NEED
Research shows endurance sport lasting 2 hours or more requires 80-120g carbohydrate intake per hour
THE FUEL YOU NEED
For endurance events lasting over 2 hours, consuming 80–120g of carbs per hour is key for peak performance. BETA Fuel 80 offers an optimised 80g of carbohydrate in a single, convenient dose. Maltodextrin is a form of glucose and is taken up directly by absorbed working muscles, delivering fast-release energy essential for endurance. Fructose is processed by the liver, providing a slower, sustained release of energy that supports prolonged performance and increases total carbohydrate availability.
AN OPTIMISED DUAL-SOURCE FORMULA
An optimal 1:0.8 ratio of maltodextrin supports greater carbohydrate intake per hour
AN OPTIMISED DUAL-SOURCE FORMULA
As an endurance athlete (events typically lasting > 2 hours) taking on 80 – 120g of carbohydrate per hour is crucial for maintaining maximal performance.
Fuelling with SiS BETA FUEL 80 at a rate of 120 g/h (with a 1:0.8 ratio of maltodextrin to fructose) during 3 h of cycling exercise reported peak oxidation rates of 1.58 g/min with a 72% oxidation efficiency, highlighting the BETA FUEL range as the most complete fuelling solution in endurance sport.

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.

Ottimi in ogni situazione

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
