Drugstore hydration supplement aimed at restoring electrolytes during exercise and travel, HIGH5 Electrolyte Tablet. Clean, sugar-free formulation helps active people feel refreshed without extra calories. Is the tablet format and measured electrolyte mix the right fit for regular training and long journeys?

⚡ At a Glance
  • Hydration Performance: Replenishes sodium (250 mg), potassium (70 mg) and magnesium (56 mg) per 4 g tablet
  • Best for: Endurance athletes, travellers, and people fasting or following low-carb diets
  • Not ideal for: Those who need carbohydrate or calorie replacement during exercise

Effervescent tablets dissolve in water to deliver a sugar-free electrolyte mix with added vitamin C. Useful for on-the-go hydration during training, travel, fasting and ketogenic plans.


Faster fluid balance restoration – thanks to balanced sodium and potassium levels

Each 4 g tablet supplies sodium 250 mg and potassium 70 mg alongside magnesium 56 mg and calcium 9 mg. These electrolytes support fluid retention and muscle and nerve function by replacing minerals lost through sweat.

Quicker recovery from sweat loss reduces the chance of cramp and helps maintain endurance during prolonged activity.

Calorie-free hydration – with a sugar-free, naturally flavoured formulation

Formulated without sugar and containing 0 calories, tablets use natural flavourings and include 28 mg vitamin C plus 1 mg green tea per tablet. The absence of sugar means no added carbohydrates when rehydrating.

Suitable for calorie-conscious exercisers and those on fasting or ketogenic regimens who still require electrolyte support.

Simple, portable use – thanks to effervescent tablet format

Tablets dissolve in plain water for an instant drink and come in multi-tablet packaging with orange and cherry flavours. Tablets are lightweight and require no measuring for every serving.

Convenient for long flights, backpacking and training sessions where carrying powders or bulky drinks is impractical.
