Description

Precision Electrolyte Capsules are an ideal way to top up sodium during long training sessions, races and hot conditions, especially when mixing drinks or carrying extra bottles is not practical.

Each capsule contains 250mg of sodium, allowing athletes to manage salt intake more accurately during longer efforts. Precision also include small amounts of potassium, calcium and magnesium in the capsule formulation.

At Ready Sweat Go, we like these for the situations where normal hydration gets awkward.

Long ultra with aid stations? Big summer ride? Hot day where you’re relying on plain water? These are the kind of small, easy-to-carry capsules that give you more control without needing to mix another bottle.

They are especially useful if you:

• sweat heavily  
• notice salt marks on your kit  
• rely on water from aid stations  
• prefer plain water to flavoured electrolyte drinks  
• want to separate sodium intake from carbohydrate fuelling  
• are racing or training for several hours at a time  

Swallow whole with water. Precision recommend taking each capsule with a few good mouthfuls of fluid.

Why Ready Sweat Go loves Precision Electrolyte Capsules.

For when you don't want (or need) an electrolyte drink.


When the distance goes up, the weather gets warmer, or you know you sweat heavily, having a fast way to top up sodium can be useful.

These capsules are light, easy to carry and give you more control when you’re using plain water, filling up at aid stations, or managing fuel separately from hydration.

A fantastic solution for quick hydration and extremely portable.

Precision Hydration - FAQs

What is Precision Hydration?

Precision Hydration is an electrolyte system designed to replace sodium lost through sweat during endurance training and racing.

Products are labelled by sodium strength, allowing athletes to choose hydration based on how much sodium they lose, rather than relying on a single generic electrolyte drink.

This approach helps athletes hydrate more accurately, particularly during longer sessions, warmer conditions, or high sweat rates.
Why does sodium matter in hydration?

Sodium is the primary electrolyte lost in sweat and plays a key role in fluid absorption, nerve signalling, and muscle function. Replacing sodium appropriately helps support hydration, comfort, and performance during endurance exercise.

Because sodium loss varies widely between individuals, replacing too little or too much can both cause problems.

Precision Hydration focuses on matching intake to actual sweat loss rather than guessing.
What are Precision Electrolyte Capsules?

Precision Electrolyte Capsules are swallowable capsules designed to help athletes top up sodium during endurance training and racing.

Each capsule contains 250mg sodium, plus small amounts of potassium, calcium and magnesium.
When should I use electrolyte capsules instead of tablets or drink mix?

They make sense when carrying bottles or mixing drinks is awkward, when you’re relying on water from aid stations, or when you prefer plain water but still want to take on sodium.

Precision specifically positions them for times when carrying pre-mixed drink or electrolyte tablets is not practical. 

Many athletes adjust strength depending on weather, duration, and intensity.
How do I take them?

Swallow the capsule whole with water. Precision recommend chasing each capsule with at least a few good mouthfuls of fluid.
Can Precision Hydration help with cramping?

Cramping can have multiple causes, but inadequate sodium intake is a common factor for some endurance athletes, particularly during long or hot sessions.

Replacing sodium appropriately through hydration can help reduce the risk of cramps related to electrolyte imbalance. Precision Hydration’s strength-based system makes it easier to match sodium intake to sweat loss.
Do they contain carbohydrates?

No. These are for electrolyte/sodium support, not fuelling.

If you need energy, use them alongside your usual fuel such as Tailwind, Precision gels/chews, Veloforte or other carbohydrate sources.
Who are they best suited to?

They are useful for runners, cyclists, triathletes and adventure racers doing longer efforts, especially in warm conditions or when total sweat losses are high.

Precision says they are popular with athletes doing ultra-distance running, cycling events, 70.3 and Ironman triathlon, and adventure races.  
Are Precision Hydration products vegan and allergen-friendly?

Yes. Precision Hydration products are suitable for vegans and are free from common allergens, including gluten, dairy, and soy.
As with any nutrition product, athletes with specific medical allergies should always check the ingredient list before use.
