your questions, answered

WHY IS HYDRATION IMPORTANT IN A HEATWAVE?

Hot weather increases sweat loss, which means you lose both fluids and key electrolytes. Replacing them helps support energy, focus and everyday performance.

Electrolytes help support:

Hydration
Muscle function
Energy levels
Focus and concentration
Performance during longer efforts

Replacing them properly can help you feel stronger, sharper, and more consistent during training and racing.

IS WATER ALONE ENOUGH IN HOT WEATHER?

Not always. Water replaces fluids, but it doesn’t replace the electrolytes lost through sweat. Hydro tabs help restore sodium, potassium and magnesium for more effective hydration.

Each sachet combines:

Over 900mg electrolytes for effective hydration
Natural caffeine for a smooth energy boost
L-Theanine to support calm focus
Lion’s Mane Mushroom and Panax Ginseng for cognitive support
Vitamin B complex to help reduce fatigue
No artificial sweeteners, fillers, or unnecessary additives

So instead of just replacing what you lose in sweat, you’re also supporting concentration, energy, and overall performance — whether you’re heading into a long run, race, early session, or busy day.

It’s designed for runners who want hydration that also helps them feel switched on before training, races, or busy days.

DO HYDRO TABS CONTAIN SUGAR?

No. Hydro tabs contain no sugar, no artificial sweeteners and under 10 calories per tablet.

WHEN SHOULD I USE HYDRO TABS?

Use them anytime you need extra hydration support — during heatwaves, before or after training, while travelling or throughout busy summer days. You can take up to 4 tablets per day.

WHAT ELECTROLYTES ARE IN HYDRO TABS?

Hydro tabs contain five key electrolytes: sodium, potassium, magnesium, calcium and chloride.

WHAT MAKES FOURFIVE HYDRO DIFFERENT?

Hydro tabs are Informed Sport tested, award-winning and developed by former international athletes using clean, effective ingredients with no unnecessary fillers.
