Precision Hydration 1500 Electrolyte Tablets - 10 Tablets

This is a tube of 10 Precision Hydration 1500 Electrolyte Tablets. Some athletes lose an extraordinary amount of sodium when they sweat. If you finish a long session with white salt residue on your skin, feel like standard sports drinks never quite do the job, or regularly suffer from cramping and fatigue despite drinking plenty of fluid, the problem is likely sodium, not just hydration. The PH 1500 is built specifically for this athlete. At 1,500mg of sodium per litre, it is the strongest tablet in the Precision Hydration range and roughly three times the concentration of a typical sports drink.

One tablet dissolves in 500ml of water to produce a potent, low-calorie electrolyte drink designed to match what heavy sweaters actually lose, rather than what the average person loses.

How to Use

Drop one tablet into 500ml of water and allow to fully dissolve before drinking. For pre-loading before a long event, consume one to two tablets in the 60 to 90 minutes before the start. During training or racing, use one bottle per hour as a baseline and adjust based on conditions, duration, and how your body responds. Can be combined with PF gels, chews, or carbohydrate drink mix to manage fuel and hydration separately.

Why Heavy Sweaters Need More Sodium

Sweat sodium concentration varies enormously between individuals, sometimes by a factor of four or more. An athlete with high sweat sodium can lose well over 1,500mg of sodium per litre of sweat. Replacing that with a standard 300 to 500mg per litre sports drink creates a growing sodium deficit over the course of a long effort, regardless of how much they drink. That deficit drives dehydration, muscle cramps, and performance decline that more fluid alone cannot fix.

The PH 1500 closes that gap. It is also effective as a pre-loading drink before long or demanding events, helping top up plasma sodium levels before sweat losses begin, which gives the body more buffer to work with during exercise.

Where It Sits in the Range

The PH 1500 is the top of the Precision Hydration tablet range, sitting above the PH 1000 (1,000mg sodium per litre) and the PH 500 (500mg sodium per litre). It is not the right choice for every athlete in every condition, but for those who genuinely sweat heavily or who train and race in the Australian summer heat where fluid and sodium losses are high, it is often the only strength that delivers meaningful results.

Low Calorie, Lightly Flavoured

Despite its high sodium content, the PH 1500 remains low in calories. A small amount of glucose is included to support sodium absorption, but the formula is designed to sit quietly alongside your fuel strategy rather than competing with it. The mild flavour stays drinkable across multiple bottles without becoming overpowering.

What Is in Each Tablet

Each tablet dissolved in 500ml delivers 750mg of sodium, plus potassium, magnesium, and a small amount of glucose to assist absorption. Vegan, vegetarian, gluten-free, and dairy-free. 10 tablets per tube.

The PH 1500 is Informed Sport certified, batch tested for banned substances, and trusted by professional triathletes and endurance athletes worldwide.

Who Is It For?

The PH 1500 suits athletes who sweat heavily, notice white salt marks on their skin or clothing after training, regularly experience cramping or dehydration despite adequate fluid intake, or who race in hot and humid conditions such as those common across Queensland, Western Australia, and the Northern Territory. It is widely used by IRONMAN and ultramarathon athletes who are on course for many hours in demanding conditions.
