The Spruce hydration guide
Water flavouring, electrolytes & magnesium drinks, sorted.
Spruce makes three things: water enhancers (real-fruit sachets that turn flat tap water into something you actually want to drink), electrolyte sachets (sodium, potassium and magnesium for training and heat) and a magnesium glycinate drink for sleep and recovery. The quiz above matches you to the right one in 60 seconds. The guide below explains the difference.
Best water flavouring in the UK
If you struggle to drink enough water, a sugar-free water enhancer is the easiest fix. Spruce sachets use real freeze-dried fruit, no artificial sweeteners, no aspartame, and add vitamins B & C to every glass. One sachet flavours 500 ml.
Electrolyte powder & sachets, UK
For training, hot weather or hangovers, plain water isn’t enough. Our Lemon & Pomegranate electrolyte replaces sodium, potassium and magnesium without the sugar bomb of mainstream sports drinks.
Magnesium drink for sleep & recovery
Peach Perfect Magnesium is a magnesium glycinate drink built for the evening wind-down. Stir into water, sip 30 minutes before bed, wake up calmer.
Hydration questions, answered
How much water should I drink a day in the UK?
The NHS suggests 6 to 8 glasses (around 1.5 to 2 litres) of fluid a day. Bodyweight, training load and climate all push that up. The quiz calculates your personal target in 60 seconds.
What is the best water flavouring without sugar?
A real-fruit sachet beats squash and syrups on sugar, calories and aftertaste. Spruce sachets are sugar-free, sweetener-free and add vitamins B and C to every 500 ml.
Do I actually need electrolytes?
If you train hard, sweat heavily, work in heat, or you’re recovering from a heavy night, yes. For everyday desk-bound hydration, a water enhancer is usually enough.
What does magnesium glycinate do?
Magnesium glycinate is the form of magnesium most associated with sleep, muscle recovery and nervous-system calm. Spruce Peach Perfect Magnesium is dosed to sip in the evening.
