GU Hydration Tabs are effervescent electrolyte tablets from GU Energy Labs designed to turn water into a light electrolyte drink for training, racing, recovery and everyday active hydration. Each tablet provides 320mg of sodium and 10 calories.

Why Choose GU Hydration Tabs?

GU Hydration Tabs provide electrolytes in a compact effervescent tablet format. Add one tablet to your water bottle to prepare a lightly flavoured electrolyte drink for training, racing, recovery or everyday active hydration.

Sodium is an important electrolyte lost through sweat, and each GU Hydration Tab provides 320mg of sodium. The formula also provides potassium.

Because each tablet contains only 10 calories and 3g of carbohydrate, GU Hydration Tabs are designed primarily for electrolyte hydration rather than carbohydrate fuelling. If carbohydrate is required during longer or harder exercise, it should be planned separately as part of your overall fuelling strategy.

How to Use GU Hydration Tabs

1. Add 1 tablet to approximately 16 fl oz (475–500ml) of water.
2. Allow the tablet to dissolve fully.
3. Drink according to your hydration needs.

You can use more or less water depending on your preferred flavour strength.

When to Use

GU Hydration Tabs can be used during training and racing, as well as for recovery or everyday active hydration when electrolyte replacement is useful.

Individual fluid and sodium requirements vary according to exercise duration, intensity, environmental conditions and sweat rate.
