THE PROBLEM

Your kid trains hard. But dehydration is quietly costing them performance.

Active kids sweat more than adults relative to their body weight — and they're notoriously bad at drinking enough before and during sport. Even mild dehydration reduces muscle endurance, slows reaction time, and increases the risk of cramps. By the time they feel thirsty, their performance is already dropping. Plain water helps, but without electrolytes, their body can't absorb or hold onto it properly.

  • -30%

    Performance drop in aerobic capacity when a child is just 2% dehydrated — a level most active kids reach mid-training without realising.

  • 70%

    Of kids don't drink enough fluid during sport to match what they're sweating out

  • 3x

    Dehydrated young athletes are significantly more prone to muscle cramps, early fatigue, and slower recovery after exercise.

THE SCIENCE

The Science Behind Hydro

1. Edmonds & Burford (2025) — Dehydration in UK primary school children rose from 17% to 40% during the school day and impaired working memory.

2. Fadda et al. (2012) — Water supplementation improved cognitive performance in 168 children aged 9-11, particularly those who were mildly dehydrated.

3. Szczegielniak et al. (2020) — 53% of children were insufficiently hydrated during school; dehydration was identified as a risk factor for concentration difficulties.

3 easy ways they can enjoy Hydro

  • As a cold drink

    Mix one sachet into 300ml of cold water and stir. Perfect for lunchboxes, sports bottles, and after-school refuelling.

  • As a warm drink

    Stir one sachet into a mug of warm water for a cosy lemon tea. Great for cold mornings and bedtime wind-downs.

  • As an ice lolly

    Pour the mixed drink into ice lolly moulds and freeze. A sugar-free treat packed with electrolytes they actually need.

6 Essential Electrolytes for Sporty Kids

  • Sodium

    Maintains fluid balance and supports hydration so the brain gets the water it needs to function.

  • Potassium

    Supports muscle function and nerve signals — critical for staying alert and energised throughout the day.

  • Magnesium

    Supports normal energy metabolism and reduces tiredness — helping kids power through the school day.

  • Calcium

    Essential for strong bones and teeth. Also plays a role in neurotransmitter release for brain function.

  • Chloride

    Aids digestion and fluid balance. Works alongside sodium to keep hydration levels optimal.

  • Phosphate

    Supports energy production and cell repair — the building blocks for growing bodies and active minds.

FAQ

Got questions? We've got answers.

What age is Hydro suitable for?

Hydro is formulated for children aged 3+ years old. The electrolyte dosages are specifically calibrated for smaller bodies. For children under 3, we recommend consulting your GP.

How does Hydro help with focus?

Even mild dehydration (1-2% body water loss) impairs concentration and working memory in children. Hydro provides a precise blend of 6 electrolytes that help the body absorb and retain water more effectively than water alone — keeping kids hydrated and focused for longer.

What does it taste like?

A naturally sweet, fruity apple and blackcurrant flavour that kids love. It's sweetened with stevia leaf extract — zero sugar, zero artificial sweeteners, and none of that salty electrolyte taste. Most kids prefer it to squash!

Can my child have Hydro every day?

Yes! One sachet per day is the recommended serving. Hydro is designed for daily use — think of it as your child's morning focus routine, like brushing their teeth.

What's your refund policy?

Full 30-day money-back guarantee. If your child doesn't love Hydro, email us and we'll refund in full. No questions asked.
