Please see specific promotion Terms & Conditions for details BFPO Addresses We do ship to BFPO addresses (with Royal Mail) but for active combat zones there is a strict 2kg weight limit (as with all deliveries to BFPO addresses), so please take this into account when ordering. As a guide, with careful packaging we can just get away with a 1.6kg tub. All orders under this weight limit will be treated as standard UK orders. All orders over this weight will be priced incrementally according to their weight (£5 per 2kg increase). If you have any queries regarding a BFPO address, please contact our Customer Service Team who will be happy to assist with your order.

ENERGY AND HYDRATION IN ONE GEL

When training or competing in hot temperatures, your body loses vital electrolytes that can limit performance. BETA Fuel + Electrolyte Gels combine dual-source carbohydrates with added sodium to help replace what you lose through sweat. Keeping you hydrated, fueled, and focused.

Designed for endurance athletes pushing through sessions lasting 2+ hours, this gel helps you reach fueling targets of 90g-120g of carbohydrates per hour, while maintaining electrolyte balance and energy stability.

Why Elite Athletes Choose BETA Fuel + Electrolyte Gels

  • Maintains carbohydrate availability for sustained energy. 
  • Replaces some key electrolytes lost through sweat to support hydration and muscle function.
  • Dual-source carbs deliver higher absorption and faster oxidation than single-source gels.
  • Proven to minimize stomach discomfort during prolonged endurance exercise.
  • One to two gels per hour help deliver both carbohydrates and electrolytes for optimal performance in warm or high-sweat conditions.

SUGGESTED USE

For training or competition in warm or humid environments lasting 2 hours or more, consume 2–3 gels per hour to achieve consumption of 90-120g of carbohydrates. Take one gel every 20 minutes to sustain energy and hydration.

Can be combined with other BETA Fuel products to customize your fueling plan and hit your personal carbohydrate and electrolyte targets.

ENGINEERED FOR ENDURANCE

ENGINEERED FOR ENDURANCE

Carbohydrate-electrolyte blends improve sodium balance and stimulate thirst, which enhances fluid retention, all of which are key to hydration and endurance in hot, high-intensity environments. This unique formula helps sustain power output, endurance, and concentration when sweat rates climb.

Carbohydrates That Keep You Moving

To maintain top performance, aim for  90-120g of carbohydrates per hour during long or demanding workouts

CARBOHYDRATES THAT KEEP YOU MOVING

BETA Fuel Energy + Electrolyte Gel is part of Science in Sport’s advanced endurance fueling range, alongside powders and chews. Each gel delivers 40g of carbohydrate in an optimized 1:0.8 maltodextrin-to-fructose ratio, designed to improve carbohydrate absorption (1), support power output (1), and minimize gastrointestinal (GI) discomfort (1). For endurance athletes—especially during events lasting more than 2 hours—carbohydrate intakes of 90–120g per hour are critical for sustaining peak performance. BETA Fuel Energy + Electrolyte Gel offers a convenient, single-serving solution, providing 40g of dual-source carbohydrate with minimal GI distress.


Research shows that fueling with BETA Fuel gels at 120 g/hour during 3 hours of cycling achieves peak exogenous carbohydrate oxidation rates of 1.6 g/min (1). This confirms the superiority of the 1:0.8 ratio over traditional 2:1 blends and demonstrates the metabolic advantages of dual-source carbohydrates for prolonged endurance performance (2).


Additionally, consuming three gels per hour (120g/hour) not only provides about 50% of energy needs in the third hour of exercise but also helps maintain carbohydrate availability, delaying the shift to fat oxidation and preserving performance (1). Importantly, BETA Fuel gels are oxidized at rates comparable to BETA Fuel drinks and chews, allowing flexible fueling strategies across formats while ensuring optimal carbohydrate delivery (1).

Stay Hydrated, Stay Sharp

Proper hydration keeps muscles firing efficiently, speeds recovery, and helps maintain mental focus. Added electrolytes—especially sodium—replace what’s lost through sweat, promoting better fluid retention and thermoregulation.


In addition to providing carbohydrates, adding extra electrolytes offers further performance benefits by replacing key minerals often lost through sweat during exercise (3,4,5,6,7,8). Supplying electrolytes (again, especially sodium) during exercise helps improve sodium balance, which in turn stimulates thirst, promotes hydration, and supports fluid retention (3,4). For these reasons, BETA Fuel Energy + Electrolyte Gel is especially beneficial during workouts or competitions in warmer conditions, when sweat rates are higher than normal, helping support thermoregulation and overall physical and mental performance (3).


BETA Fuel Energy + Electrolyte Gel provides an effective fueling solution in warmer conditions where consuming up to 120g of carbohydrate per hour is the target.
