It’s expertly crafted with a 2:1 carbohydrate blend of maltodextrin and fructose, allowing for quicker absorption and a steady release of energy to keep you going strong throughout your effort.

Formulated with 200mg of sodium, Big 40 also helps replace lost electrolytes and supports hydration—especially important when sweating hard in hot or humid conditions. The light, natural flavour makes it easy to take down, even when you're deep into a race and struggling with palate fatigue. It’s gentle on the stomach and designed to reduce the risk of digestive discomfort, so you can focus on your performance, not your gut.

The gel comes in two tailored options: a standard non-caffeinated version for steady fuelling, and a 75mg caffeine variant for athletes seeking an extra mental and physical lift. Whether it’s for a critical training session or race day, BIX Big 40 has you covered with efficient, convenient, and high-impact nutrition.

Proudly made in the UK with performance in mind, Big 40 is clean, tested, and trusted—an essential part of any endurance athlete’s fuelling plan.

BIX Big 40 Energy Gel works by supplying a powerful 40g dose of dual-source carbohydrates using a 2:1 ratio of maltodextrin and fructose. This allows your body to absorb more carbs per hour while reducing the likelihood of GI distress—ideal for long races or tough training sessions. The high carb load helps maintain your glycogen stores, staving off fatigue and keeping energy levels consistent.

Electrolyte balance is supported with 200mg of sodium per gel to combat fluid loss through sweat, helping you stay hydrated and reduce the risk of cramping. The caffeinated version adds 75mg of caffeine for improved focus and delayed fatigue—especially helpful in the final stages of a race. Together, these ingredients deliver performance-optimised fuel to keep you moving forward.
