SIS Beta Fuel Energy Drink has become a popular choice among endurance athletes seeking optimal performance during extended training sessions and competitive events.
Developed by Science in Sport (SIS), this drink aims to address the fuelling challenges that long duration activities present, with a clever blend of carbohydrates and endurance focused formulation.
WHO IS SiS?
Science in Sport (SiS) is a British sports nutrition company renowned for its evidence based, athlete focused products.
Since its founding, SiS has developed a comprehensive range of nutrition for professional and amateur endurance athletes, consistently prioritising scientific research and product quality in its formulations.
WHAT IS SiS BETA FUEL ENERGY DRINK?
SIS Beta Fuel Energy Drink is an advanced sports nutrition product specifically engineered to provide an unusually high carbohydrate content per serving.
Using a dual source carbohydrate system, it delivers both rapid and sustained energy to keep the body performing at its peak for prolonged periods.
The isotonic mix is designed for easy absorption and minimal gastrointestinal discomfort, making it especially suited for cyclists, runners, and triathletes.
WHO IS IT FOR?
This energy drink is primarily intended for endurance athletes engaging in sessions exceeding two hours.
Ideal users include cyclists, runners, triathletes, and anyone else partaking in prolonged or intense endurance exercise.
It is vegan friendly, gluten free, and free from artificial sweeteners, thus catering to a wide spectrum of dietary requirements and preferences.
WHAT INGREDIENTS DO THEY CONTAIN?
SIS Beta Fuel Energy Drink contains:
- Maltodextrin (from maize)
- Fructose
- Sodium chloride
- Natural flavouring
- Calcium lactate
- Potassium chloride
- Sodium citrate
- Magnesium citrate
- Natural sweetener (steviol glycosides)
Each serving provides around 80g of carbohydrates (in a 1:0.8 maltodextrin to fructose ratio), which is optimised for maximum absorption and reduced stomach distress.
WHAT FLAVOURS ARE AVAILABLE?
The flavours are designed to be light and refreshing, catering to varied palates during strenuous activity.
SIS Beta Fuel Energy Drink is available in 3 flavours, including:
ORANGE
The Orange flavour is probably my favourite. It has a refreshing, citrusy foundation that makes it pleasant to drink during long efforts.
It’s not overpoweringly sweet, yet still provides a zesty energy boost, which is appreciated by those who dislike sickly sweet energy drinks.
RED BERRY
The Red Berry flavour is light and extremely palatable, even during tough endurance events.
It is not overly sweet and doesn’t have any artificial aftertaste, making it an easy drink over several hours.
STRAWBERRY & LIME
Strawberry & Lime has a balance of sweetness and tartness. The strawberry provides a familiar, sweet backdrop, while a hint of lime introduces a mild tanginess.
This tart edge helps cut through any potential monotony during long exercise sessions.
WHAT DOES IT TASTE LIKE?
The flavours are designed to be palatable without being overpowering or sickly sweet.
We found them to be light, refreshing, and easy to consume, even during intense exercise.
The drink is isotonic and neutral in pH, which helps avoid any lingering aftertaste or mouth discomfort commonly associated with other high carb energy drinks.
HOW TO USE
A single sachet contains 82g of powder, which should be mixed into 500 to 600ml of water and thoroughly shaken until dissolved.
The recommended usage is one sachet per hour of exercise, sipped regularly throughout the session for consistent energy delivery.
This can be combined with SiS Beta Fuel gels or SiS energy chews to achieve a targeted hourly carbohydrate intake of 80-120g for optimal endurance performance.
