Endurance & Hydration
Endurance Supplement Vial – Vitamins & Minerals
When your body gives more, it needs more too

THE FACT
8 in 10 workers begin their workday inadequately hydrated or become dehydrated at work1.
Maintaining hydration is essential during a physically demanding workday.

SOUNDS FAMILIAR?
Do you work outdoors, spend hours on your feet, or have a job that requires continuous physical effort?
Heat and physical exertion increase the water and electrolytes you lose through sweat.

THE BRIDGE
That is why we developed the Endurance Supplement Vial – Vitamins & Minerals.
A liquid electrolyte supplement to support you on workdays when your body works harder.

Origin / why
Magnesium supports electrolyte balance and normal energy metabolism. Niacin helps reduce tiredness and fatigue.

“When we sweat, we lose not only water but also electrolytes. During periods of hot weather or intense physical exertion, it is therefore important to pay attention to both hydration and the replacement of these minerals.”

Education
01
Eye-opening fact
In 2025, 1 in 5 EU workers was exposed to extreme heat at work1.
On hot or physically demanding days, sweating causes greater loss of water and electrolytes. Maintaining hydration helps replace these losses.
02
Myth vs. reality
Myth:
“You only need to replace electrolytes when you exercise.”
Reality:
Work can make you sweat too. Physically demanding jobs, outdoor work, and high temperatures increase water and electrolyte loss. Staying hydrated is important throughout the workday.
03
Top ingredient
Did you know that magnesium does much more than contribute to electrolyte balance? It also supports normal muscle function, nervous system function, and energy metabolism2.
04
9to5 tip
Keep water within reach.
Drink water regularly during the workday, especially in hot weather or during physical work. Keeping a bottle nearby makes it easier to stay hydrated.
