About Speednut
What sets Speednut apart is its long-lasting energy release. The carefully selected blend of carbohydrates and fats delivers a steady flow of energy without relying on overly refined sugars. This not only supports endurance but also reduces the risk of GI distress, making it a reliable option for longer, tougher sessions. It’s a formula trusted by top ultra runners, who know how important consistency is when pushing their limits.
Taste matters too, and Spring delivers. With a smooth mix of hazelnut, blueberry and raspberry, Speednut offers a genuinely enjoyable flavour that doesn’t overwhelm the palate. It’s energy you’ll look forward to taking. Whether it’s race day, a training breakthrough, or just one of those days, this gel gives you the fuel and mental clarity to move with confidence.
We’re proud to exclusively offer Spring Energy products in the UK, and Speednut is one of the standout options for athletes looking to go further, harder, and stronger when it really counts.
How does it work
Speednut works by combining two powerful energy sources: medium-chain fatty acids and complex carbohydrates. These nutrients are absorbed and utilised differently in the body, providing both fast-acting and slow-burning fuel. The medium-chain fats are metabolised quickly by the liver into usable energy, while the carbohydrates are converted into glucose for extended endurance. This dual-action approach ensures a steady energy supply, reducing spikes and crashes.
The added 50mg of caffeine enhances focus and reduces perceived effort by acting on the central nervous system. It blocks fatigue-inducing receptors in the brain, which helps keep you mentally alert and physically ready to perform, especially in the later stages of effort when it’s easy to fade.
