Precision Hydration PH 250 Tablets create an electrolyte drink at 250mg sodium per litre when mixed according to the manufacturer’s instructions. The low-calorie effervescent electrolyte tablets are intended to support day-to-day hydration and lighter electrolyte needs, 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 lower-strength option is designed primarily for everyday use, so check that it is appropriate for your training and sweat losses.
