The truefuels performance gel is an energy gel specifically formulated to deliver the essential components required for endurance performance. Developed by athletes who understand what it takes to compete at the highest level, our gel provides hydration, immediate energy, and recovery support—while eliminating flavour fatigue with its carefully crafted neutral taste.
Our energy gel is crafted with a precise blend of carbohydrates, electrolytes, and hydration agents that work in harmony to:
Fuel your muscles: quick-acting carbohydrates provide immediate energy when needed.
Enhance hydration: essential electrolytes maintain fluid balance.
Support recovery: a balanced formulation helps replenish glycogen and aids post-exercise recovery.
Steady release system: endorsed by leading sports scientists, our gel delivers a continuous release of energy for sustained performance.
Water: filtered and purified for essential hydration.
Maltodextrin: a long chain of glucose molecules rapidly broken down and absorbed (via SGLT1) for immediate energy.
Fructose: a natural sugar from fruit, absorbed via GLUT5, which complements maltodextrin and supports liver glycogen restoration.
Coconut Water Powder: provides electrolytes and essential vitamins/minerals for hydration and overall health.
Himalayan Salt: supplies essential sodium to maintain fluid balance during exercise.
Tri Magnesium Citrate: a highly bioavailable form of magnesium in a triple citrate formulation, offering enhanced solubility and absorption to help prevent cramps and support overall performance.
Potassium Sorbate: an antimicrobial agent that extends shelf life by preventing mould, yeast, and bacteria.
The performance gel results from a unique collaboration between top athletes and experts. It was co-designed by Olympic champion Alistair Brownlee and Nigel Mitchell, alongside renowned academics and a network of dedicated co-creators. With decades of experience, the latest research, extensive lab work, and rigorous field testing, we’ve crafted the ultimate performance gel to fuel your endurance and elevate your game.
Each gel provides 40g of carbohydrates (approximately 160 calories). One gel per hour is generally sufficient for low-intensity exercise; up to three gels per hour may be required for high-intensity activities or long endurance events. There are no set daily guidelines; base your usage on your exercise intensity.
How do I know how to use the gel? Usage instructions are clearly outlined on the packaging. Consume the gel pre-, during, or post-activity to replenish energy and electrolytes.
Can I mix the gel with water? We recommend mixing multiple gels in one water bottle for an easy-to-drink solution that enhances hydration. Alistair prefers the simplicity of a one-bottle fuelling strategy and has used it for Ironmans, Gravel races and many more endurance events.
Should I also drink water while using the gel? Staying well-hydrated is essential for assisting with carbohydrate absorption and proper hydration.
What is the difference between the 0.25g and 1g salt versions? The 0.25g version contains 40g of carbohydrates and 0.25g of salt, while the 1g version contains 40g of carbohydrates and 1g of salt. This variation allows you to tailor your salt intake based on your sweat rate and environmental conditions.
Can I combine the two versions? Yes, you can combine them to create a personalised fueling strategy.
Is the gel vegetarian and vegan? Yes, the truefuels performance gel is vegan.
Are there any allergens? Our products are made with clean, certified gluten-free ingredients and are free from common allergens. Please review the packaging for the full ingredient list.
How long does it take for the gel to take effect? Carbohydrate uptake begins within 15–20 minutes, peaks around 30–45 minutes, and is most absorbed within 60–75 minutes. That is why athletes frequently begin fuelling before the start of an event.
How does the gel impact dental health? Formulated to be only slightly acidic to minimise acid-related dental issues.
How does the truefuels gel compare nutritionally with other energy gels? Our gel offers clean, essential nutrition with maximum carbohydrate absorption and balanced electrolytes—providing a performance edge over traditional gels with artificial additives.
Each athlete’s fuelling needs vary based on individual factors, such as sweat rate, environment, and exercise intensity. Personalising your fuelling strategy helps prevent running low on glycogen (”hitting the wall”), dehydration, and overhydration, and maintains the correct sodium levels, maximising performance and recovery.
truefuels is designed to complement your overall nutrition plan by providing a clean, science-backed fuelling solution that supports your training, performance, and recovery. Integrating our products into your routine ensures you have the right balance of energy and hydration before, during, and after exercise
Before exercise, begin with plain water and consider taking a truefuels performance gel to top off your glycogen stores. This primes your body for activity by ensuring you’re well-hydrated and energetically prepared.
Carbohydrate fuelling needs vary based on exercise intensity, environmental conditions, and individual factors. In general, take between one and three gels per hour.
Carbohydrates are the primary fuel source for your body, especially during high-intensity exercise. Here’s why they are essential for peak performance:
Energy Source: your immediate source of energy is blood glucose, which your muscles rapidly use to provide the energy needed.
Glycogen Storage: glucose is stored in your muscles and liver as glycogen. These glycogen stores act as a readily available reserve that your body taps into during prolonged or intense exercise, helping to delay fatigue.
Enhanced Endurance: maintaining adequate carbohydrate levels ensures your muscles have the sustained energy required to perform at high intensities for longer durations. This is critical for endurance events where constant energy delivery is key.
Optimal Brain Function: carbohydrates also fuel your brain, supporting cognitive functions such as focus, coordination, and decision-making, which are crucial during competitive performance.
Efficient Recovery: consuming carbohydrates before, during, and after exercise helps replenish glycogen stores, accelerating recovery and preparing for subsequent training sessions or competitions.
Sodium is essential for maintaining fluid balance, nerve function, and muscle contraction. It helps prevent cramps and fatigue, making it a key component in any performance nutrition plan.
Dark urine, fatigue, dizziness, and dry mouth are signs of dehydration. Monitoring your body weight and urine color during exercise can help you gauge your hydration status.
Hyponatremia is a condition caused by abnormally low sodium levels, often resulting from excessive water intake without proper electrolyte replenishment. Avoid it by balancing your fluid intake with sodium-containing products like truefuels performance gel.
While sodium is essential, excessive intake can cause gastrointestinal discomfort and other health issues. Following recommended guidelines and tailoring your intake to your needs is important. Our truefuels products are formulated to deliver the optimal balance for performance.
