Hydration Tabs Mixed Box

What Our Gearhead® Experts Are Saying:

"I started dropping a GU Hydration Tab into my bottles on longer rides instead of reaching for heavier mix-in drinks, and have not looked back. The 320mg of sodium per tab is genuinely meaningful over a three or four-hour effort in the heat, and the light flavor means I can drink consistently without palate fatigue setting in around hour two. The mixed box is a smart way to stock up and keep things interesting across a full week of training."

Somewhere around the two-hour mark on a hard summer ride, plain water stops doing its job. Sweat has already pulled sodium and potassium out of your system, your body is working harder to maintain fluid balance, and the performance drop that follows dehydration is not far behind. The GU Hydration Tabs Mixed Box is the simplest possible intervention, one tab per bottle, and your water becomes a properly formulated electrolyte drink that actually supports what your body needs to keep pushing.

Each tab delivers 320mg of sodium and 55mg of potassium, the two electrolytes most directly tied to fluid retention and muscle function during sustained effort. At just 10 calories per serving and sweetened with stevia and cane sugar, the formula is clean enough to use across every bottle on a long ride without tipping your calorie or sugar balance. The effervescent dissolve is fast and complete, leaving no residue or grit in your bottle, which matters when you are already managing gels, bars, and nutrition timing on the bike.

The mixed box includes four tubes covering Lemon Lime, Orange, Tri-Berry, and Strawberry Lemonade, giving you enough variety to rotate flavors across a full training block without flavor fatigue becoming a reason to under-drink. Vegan, gluten-free, and tested through Informed Choice for banned substances, these tabs fit cleanly into any competitive athlete's nutrition system, whether you are logging base miles, doing threshold intervals, or racing through a long gran fondo.
