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.

SUGGESTED USE

Depending on your sport or event, consume 1–3 gels per hour to reach your 90–120g carbohydrate target. Tear, squeeze, and go as needed during training or competition.

Combine with other BETA Fuel products to meet your hourly carbohydrate goals.

ENHANCED BY SCIENCE

BETA Fuel uses a precise balance of maltodextrin and fructose in a 1:0.8 ratio to increase the total amount of carbohydrate your body can absorb and use during exercise, improving endurance and reducing fatigue in long-distance training or racing.

The Energy Your Body Demands

Research shows that endurance exercise lasting two hours or longer demands a steady intake of 90–120g of carbohydrates per hour to sustain peak performance.

The Energy Your Body Demands

When energy stores drop, fatigue sets in quickly, reducing power, pace, and focus. BETA Fuel Energy Gel delivers an optimized 40g of carbohydrate per serving in a simple, convenient form that absorbs fast and works efficiently.

Each gel contains two types of carbohydrates—maltodextrin and fructose—balanced for performance. Maltodextrin, a form of glucose, is rapidly absorbed by working muscles, providing quick-release energy for immediate output. Fructose, on the other hand, is processed through the liver and releases energy more slowly, extending endurance and increasing total carbohydrate availability. Together, they create a powerful, sustained energy system that helps you maintain pace, delay fatigue, and go the distance in even the toughest conditions.

AN OPTIMISED DUAL-SOURCE FORMULA

The science behind BETA Fuel lies in its 1:0.8 ratio of maltodextrin to fructose, proven to increase the amount of carbohydrate your body can absorb and use each hour.

AN OPTIMISED DUAL-SOURCE FORMULA

For endurance athletes—training or racing for 2 hours or more—this balance allows for higher carbohydrate intake without the digestive discomfort often caused by single-source energy gels.


In endurance testing, athletes who were fueled with BETA Fuel gels at 120g of carbohydrates per hour using the 1:0.8 ratio during three hours of cycling achieved peak carbohydrate oxidation rates of 1.58g per minute with an impressive 72% oxidation efficiency. These results show that BETA Fuel maximizes energy delivery and utilization, helping your body perform longer and recover faster. It’s a complete, scientifically proven fueling solution built for athletes who push beyond limits and demand results.
