For athletes

Train hard. Rehydrate harder.

An hour of hard training can cost you over a litre of sweat — and the sodium, potassium and chloride that keep muscles firing. Put back what the session took out.

What sweat actually costs you

Sweat is not just water. Every litre carries out sodium, potassium and chloride — the minerals your muscles and nerves run on. Train in serious heat and losses climb further.

Replace only the water and you dilute what is left; that is when the heavy legs, cramps and post-session headache show up.

Water vs sports drinks vs electrolyte formulas

  • Water — right for short, easy sessions.
  • Sports drinks — electrolytes plus a substantial sugar load; most gym sessions do not need that fuel.
  • Hydralyte — five essential electrolytes and 500 mg Vitamin C per prepared 500 ml serve. Formulated for fast fluid absorption, not a sugar hit.

How athletes use it

  • Before: one serve with your pre-training meal on heavy or hot days.
  • During: sip a prepared serve through sessions over 60 minutes.
  • After: one serve within 30 minutes of finishing, alongside your normal recovery meal.

Weigh yourself before and after a hard session: every kilo lost is roughly a litre of fluid to replace over the following hours.

Made for heat-country training

Outdoor runs in serious heat, padel at midday, football under lights — heat multiplies sweat rate and makes electrolyte replacement the difference between backing up tomorrow and writing the week off.

Use the hydration calculator to set a daily target that matches your training load and heat exposure.

Frequently asked questions

Is this a pre-workout or energy drink?

No — no caffeine, no stimulants. It replaces fluid and minerals; pair it with your normal nutrition.

Jars or powder sachets?

Sachets dissolve fast in a shaker and carry easily in a gym bag; jars are more economical per serve if you train daily.

Will it break a fast?

It is not zero-calorie; if you train fasted, time your serve for after the session.

Back up tomorrow. Rehydrate today.
