Hydration questions,
answered.
The basics, before you take the quiz.
How much water should I drink a day in the UK?
The NHS suggests 6 to 8 glasses of fluid a day. Your body weight, how active you are and the temperature around you all push that up, which is what the quiz works out.
What’s the best water flavouring without sugar?
A real-fruit sachet beats squash and syrups on sugar. Every Spruce sachet is sugar free, sweetened with stevia, with real fruit powder leading the blend.
Do I actually need electrolytes?
If you train hard, sweat a lot or spend time in the heat, daily electrolytes are an easy way to add minerals to your water. For a desk day, a water enhancer is usually all you need.
What’s in Wind-down?
Wind-down is a peach magnesium drink with 250mg of magnesium and vitamin B6. Magnesium and vitamin B6 contribute to the reduction of tiredness and fatigue.
