We recommend 500 ml of cold water for an optimal ratio and great taste. Some customers prefer 750 ml or even one litre. It depends on taste preference, activity level, and how much you have sweated.

EirLyte is a scientifically formulated, sugar-free electrolyte powder designed to deliver effective hydration and support performance. Created for athletes, fitness enthusiasts, and health-conscious individuals, EirLyte uses natural ingredients and clean minerals to fuel your body without added sugars, artificial sweeteners, or synthetic chemicals.

Unlike conventional hydration drinks loaded with sugars and artificial additives, EirLyte is made with natural flavorings, Irish Mineral Sea Salt, stevia, and a balanced blend of electrolytes. It’s designed for rapid rehydration and clean performance, without compromising on taste or health.

Electrolytes—such as sodium, potassium, and magnesium—are essential for fluid balance, nerve signaling, and muscle function. When you sweat during exercise or heat exposure, you lose these minerals. Replacing them helps prevent dehydration, cramping, fatigue, and dangerous conditions like hyponatremia (low sodium levels).

Yes. EirLyte is formulated for athletic and high-performance use and is Informed Sport certified. Every batch is tested for banned substances, heavy metals, and contaminants—meeting the highest safety and quality standards.

No. EirLyte is 100% sugar-free. We use stevia, a natural, zero-calorie sweetener, for a clean, refreshing taste without blood sugar spikes or unnecessary calories.

If you have high blood pressure, kidney disease, heart conditions, or follow a low-sodium diet, consult your doctor first. EirLyte contains 925 mg sodium per serving—purposefully designed for active individuals who can lose 1,000–3,000 mg sodium per hour through sweat. Research shows moderate sodium intake balanced with potassium and magnesium does not raise blood pressure in healthy individuals.
