Precision Hydration 250mg Sodium Electrolyte Capsules - 15 Caps

This is a pack of 15 Capsules of Precision Hydration 250g Sodium Salt Electrolyte. Not every race or training session gives you the option to mix up a drink. Aid stations hand you cups of water. Trail runs take you far from anywhere you can prepare bottles. Some athletes simply prefer plain water over any flavoured drink, no matter how mild. The Precision Fuel and Hydration Electrolyte Capsules are built for exactly those situations.

Each blister-packed capsule delivers 250mg of sodium, giving you a precise, portable, and practical way to replace the electrolytes you lose through sweat without needing to change what you drink. You swallow a capsule, drink your water, and get on with racing.

How to Use

Swallow one capsule with 500ml to 750ml of water. Typical intake is one to three capsules per hour depending on sweat rate, conditions, and exercise duration. Increase intake in hot or humid conditions or during very long efforts. Take your first capsule before you start sweating heavily rather than waiting until you feel thirsty or depleted.

Why Sodium Matters

Sodium is the primary electrolyte lost when you sweat, and it does more than just prevent cramp. Adequate sodium intake during exercise helps the body retain fluid more effectively, supports nerve function and muscle contraction, and maintains blood plasma volume. Athletes who do not replace sodium during long or hot efforts often end up over-drinking plain water, which can dilute blood sodium levels and create its own set of performance and health problems.

Individual sodium losses vary considerably. Sweat rate and sweat sodium concentration differ significantly from person to person, and both increase with heat, humidity, and exercise intensity. These capsules allow you to adjust your sodium intake capsule by capsule based on your own needs, conditions, and how long you are out there, rather than being locked into a fixed concentration in a premixed drink.

A Versatile Format for Any Situation

The blister pack format keeps capsules dry, easy to count, and straightforward to carry in a jersey pocket, race bib, running vest, or transition bag. There is nothing to mix, nothing to open carefully, and no risk of spilling. You push a capsule out of the blister, swallow it with water, and keep moving.

The capsules are also useful for topping up the electrolyte content of other drinks. If you are using a carbohydrate-only drink mix during a long ride and need more sodium than it provides, adding a capsule or two per hour is a clean and controllable way to do it.

What Is in Each Capsule

250mg of sodium per capsule from sodium chloride and sodium citrate, plus small amounts of potassium and magnesium. No artificial colours, no sweeteners, no flavour. Vegan, vegetarian, gluten-free, and dairy-free. 15 capsules per box.

The Electrolyte Capsules are Informed Sport certified, batch tested for banned substances, and appropriate for use by competitive athletes at all levels.

Who Is It For?

The Electrolyte Capsules suit any endurance athlete who sweats heavily, trains or races in the heat, or competes in events where mixing drinks is not practical. They are particularly useful for ultramarathon runners, trail runners relying on water sources, and triathletes who prefer to keep their bottles dedicated to carbohydrate without adding more sodium than they need.

They also work well as a backup or supplement to Precision Hydration electrolyte tablets or drink mixes for athletes who find they need more sodium than their standard hydration plan delivers.
