Why Electrolytes Matter

Sweat isn't just water. Every hour of hard training you lose sodium, potassium, and magnesium — the minerals that keep muscles contracting, nerves firing, and fluid balance intact. Without replacing them, performance degrades fast: cramping, early fade, and cognitive drop all trace back to electrolyte depletion. Truefuels Electrolytes give you a precise, clean dose of exactly what endurance training demands. No sugar, no filler, no guesswork.

Facts

Why this formula?

Most electrolyte products get the sodium wrong — too little to make a real difference, or mixed with artificial sweeteners and colours that add nothing useful. This formula is built around a 1g Himalayan salt serving because sodium is the electrolyte you lose most through sweat, and it needs to be replaced at a meaningful dose to actually work. Potassium and magnesium are included in highly absorbable citrate forms, so what you take in actually reaches your muscles. Coconut water powder adds a natural trace mineral base. Clean ingredients at doses that reflect what endurance effort actually demands.

Who is this for?

For anyone who moves and sweats. Water alone doesn't replace what your body's loses. Whether you're training for a race, heading to the gym, playing sport, or just staying active through the day, electrolytes are part of proper hydration, not just an endurance extra. If you've ever felt low energy, heavy-legged, or sluggish despite drinking enough water, electrolyte depletion is likely part of the reason. Truefuels Electrolytes work as everyday hydration support — clean, natural, and easy to take anywhere.

Quality Ingredients

Four electrolytes in forms your body can actually use. Nothing artificial.

Pink Himalayan Salt
Providing sodium, and chloride. At 1g per sachet, this is a real dose — not a token electrolyte presence.

Potassium Citrate
Works with sodium to keep fluid balanced in your cells and muscles contracting properly. Citrate form absorbs better and is gentler on the gut than cheaper alternatives.

Magnesium Citrate
A proper dose that your body can actually absorb. The citrate form gets into your system — most passes straight through with cheaper versions.

Coconut Water Powder
Adds natural trace minerals to round out the formula beyond isolated salts alone.

Stevia (Steviol Glycosides)
Natural plant-derived sweetener. Clean taste, no sugar, no artificial chemistry.

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

28.04.2026|truefuels Energy Gels

These are excellent gels. Not too sweet and easy to take. I also find them gentle on my stomach, no issues, so I'm very happy.

28.04.2026|truefuels Energy Gels

Tastes good and hasn’t caused any GI issues. Mix of salt levels is a nice touch and whole product give confidence to performance!

28.04.2026|truefuels Electrolytes

Nice flavour and gave me the replenishments needed!

28.04.2026|truefuels Energy Gels

During last weekends Bath Beat Cross Country marathon, I hit the wall around 18-19 miles in, I was ready to through the towel in, my legs had had it,(the temperature was 22 degrees) I was running this after running the Paris Marathon less than two weeks earlier, I drank some of the true fuels electrolytes followed by your energy gel with 1g, within 4-5 min I really started to feel better and went on to finish the marathon feeling good at the finish! I normally use SiS , but will be using Truefuel from now on!! And will be taking these to the Ironman world championships in Kona in October.

27.04.2026|truefuels Electrolytes

Arrived promptly. Flavour tastes good and great to be able to replace my salts so easily through a drink. Really happy with the product.

21.04.2026|truefuels Energy Gels

No stomach issues during long runs up to 22 miles with 5 or 6 gels. Only 4 stars as had several split whilst running.

19.04.2026|truefuels Electrolytes

Great product definitely trying more no tummy issues easy to mix neutral flavour Great for long Training days

19.04.2026|truefuels Energy Gels

Had some issues with this order, coming from UK to Spain was stopped at customs. Client Service went the extra mille yo make it possible so even it came very delayed, I'm grateful. Well done! Product excellent 👌

17.04.2026|truefuels Electrolytes

Carb gel with sodium is great. Tearing off the package is not tricky. Its liquid form makes it easier to consume. It won't cause flavor fatigue. BUT taste is toooo sweet... this sweetness causes another type of taste fatigue.

15.04.2026|truefuels Energy Gels

Used during the Paris Marathon 2026. Never cramped, got a stitch, or had any stomach discomfort, which I’ve had with other gels.

What makes our electrolytes unique?

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.

Mixing volume and timing?

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.

Can I take electrolytes and gels together?

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.

How should I adjust in hot weather?

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

Why do I need different salt levels?

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.
