If you’re looking for a way to stay hydrated without the sugar hit, High 5 Zero Electrolyte Drink is a game-changer. It’s a refreshing, sugar-free tablet that you mix with water, packed with electrolytes to keep you on top of your game, whether you’re training hard or just out for a run.
Who it’s for:
Runners, cyclists, gym-goers, hikers – or anyone who sweats heavily or needs hydration support, especially when they don’t want extra sugar or calories.
What it does:
Replaces sodium, magnesium, potassium, calcium, and chloride lost through sweat, plus vitamin C to support immunity and reduce fatigue – all without sugar or added energy. Green tea extract adds trace antioxidants.
How I would use it:
Drop one tablet into approx. 500-750ml water before, during, or after activity. It dissolves quickly – great for long workouts, flights, sauna, or everyday hydration on hot days.
The Science:
Electrolyte Drink Improves Fluid Retention and Performance during Rehydration
Study: Randomised crossover design comparing plain water versus electrolyte solution (similar sodium levels) on fluid retention, hydration markers, and exercise performance.
Medicine & Science in Sports & Exercise (2019)
https://pubmed.ncbi.nlm.nih.gov/30680320/
Electrolyte solutions with sufficient sodium significantly improve fluid retention and rehydration effectiveness compared to water alone. HIGH5 Zero’s 250mg sodium per tablet supports better hydration recovery and retention during and after exercise.
The Effect of Magnesium on Muscle Cramp Incidence in Athletes
Study: Meta-analysis of magnesium supplementation showing its effect on reducing muscle cramps and fatigue in athletes exposed to heat or prolonged activity.
Journal of Sports Sciences (2018)
https://pubmed.ncbi.nlm.nih.gov/29176104/
Magnesium intake is associated with reduced cramp frequency and lower perceived fatigue. With 56mg magnesium per tablet, HIGH5 Zero helps support electrolyte balance and may assist in combating cramping and fatigue during extended exertion.
