A clean, functional electrolyte mix delivering 400 mg sodium, 150 mg potassium, and 25 mg magnesium per serving, dosed to match the real demands of endurance training.

Sodium
supports fluid balance and helps maintain blood volume during sweating
Potassium
supports muscle function and nerve signalling
Magnesium
contributes to normal muscle contraction and helps reduce fatigue

Designed to replace what sweat takes away,before, during, or after training. Without unnecessary additives or sugar overload.

Pink Himalayan Salt

for a naturally balanced sodium source

Potassium & Magnesium Citrates

for high bioavailability and gentle digestion

Coconut Water Powder

— chosen for its natural electrolyte profile and superior quality

Natural flavours, citric acid, and stevia for a clean, refreshing taste

No artificial colours. No unnecessary fillers.

Only ingredients selected for function, absorption, and tolerance.

Ingredients:

Pink Himalayan Salt (1 g), Potassium Citrate (391 mg), Magnesium Citrate (210 mg), Coconut Water Powder (1 g), Anti-caking Agent (Silicon Dioxide), Citric Acid, Natural Flavour (Mint or Watermelon), Sweetener (Steviol Glycosides from Stevia)

Formulated to hydrate! With 0 kcal, virtually no carbohydrates or sugar, this electrolyte mix focuses purely on hydration, mineral balance, and performance consistency.

Per serving:

Energy 0 kcal · Carbohydrate ≤ 1 g · Protein 0 g · Fat 0 g · Fibre 0 g

Salt 1 g providing

400 mg sodium, 150 mg potassium, 25 mg magnesium

Ideal to stacking with truefuels Energy Gels.

1. Neutral taste. No flavour fatigue

A lightly sweet, neutral profile designed for long sessions and repeated intake without sensory overload.

2. Built for gut comfort

Refined, minimal composition developed for high carbohydrate usage while remaining gentle on the digestive system.

3. Maximum carbohydrate absorption

The 1:1 glucose–fructose ratio supports efficient uptake and helps sustain higher carb intakes when intensity and duration increase.

4. Stackable fuelling concept

Designed to integrate seamlessly with electrolytes and other TrueFuels products — allowing you to tailor energy and hydration independently.

5. Steady energy delivery

Developed from real-world endurance experience and informed by leading sports science to support consistent energy availability over time.

Fuel smart. Stack with intention.

Our products are designed to work together. Use electrolytes to manage hydration and mineral balance, and add gels or carbs when energy demand increases.

to adapt your fuelling strategy to your training load, conditions, and race goals.

One system. Built for peak performance.

Designed for endurance athletes training or racing for 60+ minutes, especially in warm conditions or high sweat rates.

Ideal for:

Runners, cyclists, and triathletes
Training sessions and races lasting
60 minutes or more
Anyone looking to fuel
without flavour fatigue or GI distress

Typical sweat sodium loss ranges widely, but for most athletes:

replacing
~1 g salt per 500 ml fluid
is physiologically appropriate
full replacement of 100% sodium loss is not required

Excessively high-sodium products (1000–1500 mg) are only suitable for extreme sweat rates and may increase GI distress for most athletes.

truefuels is designed for realistic, repeatable use, not extremes.

Most electrolyte mixes either underdose sodium or overload sugar.

This formula focuses on what actually limits performance in heat and long sessions: hydration, fluid retention, and muscle function — without unnecessary calories.

Science Corner: Why Electrolytes Matter in Endurance Performance

When we discuss electrolytes in endurance sports, we typically mean sodium, potassium, magnesium, and chloride. They are more than just “salts.” They’re essential minerals that keep your muscles firing...

This guarantee is part of truefuels' commitment to supporting athletes, ensuring that everyone can discover what works best for their performance with total confidence.

Only what your body truly needs when sweating. Minimalist formulation focused solely on essential electrolytes; no sugar, artificial flavouring, or unnecessary additives. Great tasting. Stackable logic with truefuels gels provides precise carbohydrate and sodium control for every athlete and every condition.

One sachet mixes best with 500 mL of cold water. For a lighter taste, use up to 750 mL. Drink 30 minutes before exercise or 1-3 servings per hour during training.

Yes. The electrolyte is designed to complement the truefuels performance gels. This combination allows precise control of carbohydrates and sodium intake, based on heat and duration.

In high heat or heavy sweat conditions, increase intake to 1 serve per 20-30 minutes and prioritise higher-salt gels (40/1.0).

Sweat sodium losses range from 200 mg to over 2,000 mg per L. Adjust your gel and electrolyte combination to match your personal sweat rate for optimal performance and comfort.
