Why 1,000 mg of sodium per litre? The average athlete loses ~950mg of sodium per litre of sweat, so if your sweat/sodium losses are moderate to high, a drink containing about 1000mg/l could help you stay on top of your fluid/electrolyte replenishment.

Why is sodium so important? Maintaining the sodium levels in your blood is crucial to performing at your best when you're sweating for long periods.

Sodium helps you absorb and retain fluid, which keeps your blood volume up, reducing cardiovascular strain, fatigue and potentially even cramp.

Just drinking water when sweating over long periods dilutes your sodium levels, which can really impact your performance and could lead to hyponatremia. A recent study found 10% of athletes had hyponatremia at the end of an Ironman!


What are hypotonic electrolyte drinks? Hypotonic sports drinks have a lower concentration - or thickness - than your blood. This makes them absorb faster than isotonic (similar concentration) and hypertonic (higher concentration) sports drinks, making them more effective if hydration is your main aim. Our electrolyte supplements are all hypotonic.

Hyponatremia is a condition caused by a dilution of your blood sodium levels. It's fairly common in endurance athletes because when we sweat we lose sodium and - over prolonged periods of exercise - replacing enough of what we're losing can be hard. Just drinking plain water or weak sports drinks can further dilute blood sodium levels, so adequate sodium supplmentation is important during longer events like Ironman triathlons or ultramarathons. Symptoms of hyponatremia include nausea, headaches and fatigue.
