Developed with elite feedback and rigorous research, these gels are becoming a staple for those demanding energy on the move.
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 ARE SiS BETA FUEL ENERGY GELS?
SiS Beta Fuel Energy Gels are dual source carbohydrate gels designed for endurance events, providing a hefty 40g of carbohydrate per sachet in an optimised 1:0.8 ratio of maltodextrin to fructose.
This ratio is carefully engineered to increase the efficiency of carbohydrate utilisation while limiting the risk of gastrointestinal discomfort, enabling athletes to fuel longer and harder.
WHO IS IT FOR?
These energy gels are specifically made for endurance athletes undertaking efforts longer than two hours.
Whether involved in marathon training, ultra running, or races, anyone aiming to sustain high energy levels without the digestive issues that sometimes plague such products will appreciate this gel.
WHAT INGREDIENTS DO THE CONTAIN?
The primary ingredients in SiS Beta Fuel Energy Gels include:
- Water
- Maltodextrin (30%)
- Fructose (23%)
- Natural flavourings
- Citric acid
- Sodium citrate
- Gelling agents (gellan gum, xanthan gum)
- Sodium chloride, and approved food preservatives such as sodium benzoate and potassium sorbate.
Some versions, like the nootropic range, also include caffeine and compounds like Taurine and Theanine for enhanced focus.
WHAT FLAVOURS ARE AVAILABLE?
SiS Beta Fuel Energy Gels come in several flavours, including orange, strawberry and lime, and a neutral version for those who prefer a subtler taste.
ORANGE
The Orange flavour of SiS Beta Fuel Energy Gel is well liked for its pleasant, not overpowering citrus taste.
It offers a classic orange gel flavour that is fairly natural and balanced without being too sweet or artificial.
It has a strong but palatable orange tang that is easy to consume.
STRAWBERRY AND LIME
The Strawberry & Lime flavour shares many similarities with the Orange but has a mild tangy tartness that people find refreshing.
The lime adds a subtle sharpness that cuts through the sweetness typical of carbohydrate gels, giving it a slightly lighter and zestier profile than Orange.
It is refreshing and easy on the palate.
NEUTRAL
The Neutral flavour is engineered for those who suffer from flavour fatigue or want to avoid strong tastes altogether.
It's described as “mild” and “easy-going,” reducing the risk of becoming nauseous after consuming multiple gels in long races.
Rather than being truly flavourless, it tastes subtly sweet due to the carbohydrates themselves, but without any added fruit or artificial notes.
WHAT DO THEY TASTE LIKE?
SiS Beta Fuel gels boast a pleasant, relatively natural taste without being overpoweringly sweet or artificial.
They are thicker than some gels due to the high carbohydrate content, yet not gloopy, making them easy to swallow even during intense effort.
The aftertaste is mild making them palatable even after repeat use.
HOW TO USE
For optimal performance, SiS suggests to take one to three gels per hour, aiming for an intake of 80 to 120g of carbohydrates per hour during exertion.
The gel is easy to consume, simply tear open the sachet and squeeze into the mouth.
No water is strictly required, but some may prefer to wash it down, especially during warm conditions.
SIZE AND COST
The energy gel is available individually and in boxes:
- Individual gels cost £2.20
- Pack of 6 gels costs £13.20 (£2.20 per gel)
- Box of 30 gels costs £60.00 (£2.00 per gel)
