Key Benefits

500mg Sodium Per Litre — Prepared at the manufacturer’s stated concentration.
250mg Sodium Per 500ml — One tablet mixed as directed.
Low-Calorie Formula — Separate hydration from carbohydrate fuelling.
Portable Tube — Simple to store and carry in a kit bag.
Personalised Hydration — Choose strength around your needs.

Precision Hydration PH 500 Tablets create an electrolyte drink at 500mg sodium per litre when mixed according to the manufacturer’s instructions. The low-calorie effervescent electrolyte tablets are intended to support endurance hydration plans that require a measured sodium concentration, while keeping fluid and sodium intake measurable.

Mix one tablet in 500ml of water and use it within a hydration strategy tailored to the conditions, exercise and individual sweat profile. The suitable strength depends on your sweat rate, sodium losses and total fluid intake, rather than exercise duration alone.
