Hydration supplements for your workouts, hot days and everyday life: water, sodium and vitamins in the right measure, with an isotonic drink powder when the session goes past an hour.

What makes the biggest difference, and costs nothing.

Sports hydration guide
  1. 2-2.5 litres a day

    That is what EFSA considers adequate for women and men, counting both drinks and food. If you train, add what you sweat.

  2. Under an hour: water

    In short sessions, water is enough if you are thirsty.

  3. Over an hour or in the heat

    Drink according to thirst, without replacing more than 80% of what you sweat, with 400-1,100 mg of sodium per litre.

  4. Weigh yourself before and after

    People sweat between 0.3 and 2.5 litres an hour. Weighing yourself before and after training tells you how much you sweat.

What's in each serving

5 electrolytes, 13 vitamins and carbohydrates

When you sweat, you lose water and electrolytes, especially sodium. Each serving of Nitrus provides these five electrolytes, all 13 vitamins at 100% of the NRV and about 15 g of carbohydrates, with a delicious Tropical Punch flavour.
