The New Beta Fuel Range

What is it?
Beta Fuel uses both maltodextrin and fructose to optimise carbohydrate delivery and utilisation during exercise whilst minimising gastrointestinal issues.
The combination of maltodextrin and fructose, is the key to Beta Fuel, as the transportation of nutrients across the intestinal wall is a rate limiting factor in carbohydrate oxidation during exercise.

How does Beta Fuel work?
Different types of carbohydrates have different transporters to carry glucose from the gut to the blood, with the maximum rate of a single carbohydrate source such as maltodextrin being around 60 g per hour.
Fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use.
Beta Fuel works by providing these two different forms of carbohydrate which can be simultaneously absorbed.

What’s new?
The new range of Beta Fuel products has an optimised ratio of maltodextrin to fructose. Our previous version used a ratio of 2:1, whilst the new range is 1:0.8.
The new ratio has been proven to:

  • Enhance total exogenous carbohydrate oxidation by 17%
  • Enhance mean power output during 10 maximal sprint efforts by 3%
  • Increase the percentage of ingested carbohydrate oxidised from 62% (2:1 ratio) to 74% (1:0.8 ratio)
  • Reduce symptoms of stomach fullness and nausea when compared to the 2:1 ratio

Who’s it for?
It is suggested that during endurance exercise (in excess of 2.5 hours) 80-120 g of carbohydrate per hour should be consumed to maintain blood glucose levels and prevent fatigue.
The new Beta Fuel is a performance solution for any endurance athlete that trains/competes in sessions/events over ~2 hours.

About The Beta Fuel Range
This unique range of products are all naturally flavoured and can be used in combination to optimise performance during endurance exercise, giving you a scientifically superior fuel source allowing you to unleash your energy.

Beta Fuel Powder
The new Beta Fuel powder solution will contain 80g of carbohydrate at this 1:0.8 ratio, in a neutral pH formula still maintaining the signature isotonic format to minimise gastrointestinal issues.


  • Orange
  • Strawberry and Lime
  • Red Berry

How to use
Mix one serving (82g) with 500-600ml of water and drink at 20 minute intervals during prolonged endurance exercise to meet your fuelling requirements. Mix with 600ml of water to make Beta Fuel isotonic.

Beta Fuel Gels
The Beta Fuel gel contains 40g of carbohydrate also at the 1:0.8 ratio of maltodextrin to fructose. The Beta Fuel gel with nootropics also contains 40g carbohydrate, but with cognitive enhancing nootropic compounds that give you that mental lift you might need, especially at the latter phases of exercise.
The Beta Fuel gel with nootropics contains 1g of the amino acid L-taurine, 250mg Cognizin® to enhance information processing and also 200mg caffeine with 200mg L-theanine, the amino acid which has been shown to both reduce feelings of ‘jitters’ that you get with caffeine, while increase subjective feelings of alertness.


  • Orange
  • Strawberry and Lime
  • Apple (nootropics gel)
  • Lemon and lime (nootropics gel)

How to use
Consume the Beta Fuel Gels during prolonged endurance exercise to meet your fuelling requirements.
For the Beta Fuel with Nootropics Gel we recommend consuming the nootropic gel during the latter phases of your exercise and 60 minutes prior to when you’d want to benefit from the performance effect, with a maximum of one serving per day.

Beta Fuel Chews
These chews are in a unique format to SiS, being super easy to consume sticking to the key 1:0.8 maltodextrin to fructose ratio, with 46g of carbohydrate (7g per chew).


  • Orange
  • Lemon

How to use
Consume during prolonged exercise to meet your fuelling requirements.

Fuelling strategy – 2-hour event at 80-120g of carbohydrate per hour

80g per bottle (160 g)

So what does all this mean for you?
The new enhanced Beta Fuel formula allows you to increase your carbohydrate intake to around 80-120g per hour as a result of the optimised 1:0.8 maltodextrin and fructose ratio.
This will aid your performance by minimising gastrointestinal distress and enabling faster absorption.
Though it is important to note, individuals may take time to adapt to consuming this amount of carbohydrate and the optimal amount per hour may also vary slightly depending on the individuals body weight.
It is important to practice your nutrition during training to find the optimal amount that works for you.
