How does it work

GU Energy Gel works by delivering a carefully crafted combination of carbohydrates, electrolytes, and BCAAs that support endurance performance. The dual-source carbohydrates (maltodextrin and fructose) allow for quick and efficient energy uptake, ensuring a steady release without spikes or crashes. Sodium helps maintain fluid balance by replacing salts lost through sweat, crucial for muscle function and hydration.

Meanwhile, the added BCAAs protect muscles from fatigue and help maintain mental clarity, allowing you to stay strong and focused throughout your activity.

When taken with a few sips of water, GU Energy Gel is rapidly absorbed, providing immediate and lasting energy, essential electrolytes, and muscle support to power you through tough sessions and races.
