Description

Formulated with 320mg of sodium and 55mg of potassium per tablet, these essential minerals help maintain fluid balance, support muscle function, and improve endurance, especially during extended sessions or in hot conditions. Whether you're logging long miles or recovering post-session, GU’s hydration tabs are built to keep you going strong.

The addition of xylitol not only sweetens naturally but also supports digestive comfort by reducing the risk of stomach upset, a common issue with overly sugary drinks. Available in a variety of light, refreshing flavours, they’re easy to enjoy and even easier to carry, thanks to their compact, travel-friendly tubes.

Whether you’re cycling, running, or hitting the gym, GU Hydration Drink Tabs provide effective hydration support with zero fuss. Just pop one in your bottle, let it fizz, and fuel your performance with a refreshing drink you can count on, wherever your workout takes you.

How does it work

GU Hydration Drink Tablets work by restoring the body’s electrolyte balance through targeted doses of sodium and potassium, key minerals that are lost during sweat-heavy activities. These electrolytes are essential for fluid retention and optimal muscle function, helping prevent cramps and support endurance. The fast-dissolving formula delivers these benefits quickly, ensuring you stay hydrated without the excess sugar of traditional sports drinks.

The gentle, xylitol-based sweetness ensures that your hydration strategy won’t lead to stomach upset, an essential consideration for endurance athletes and anyone with sensitive digestion. With each tablet, you get a reliable, portable hydration boost that supports performance and recovery alike.
