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.
