Comes in practical single-dose sachets, suitable for travel or a gym bag • Contains an independently tested batch (microbiology, heavy metals) with a publicly available report • Thanks to magnesium, it contributes to maintaining electrolyte balance and normal energy-yielding metabolism • Thanks to potassium and magnesium, it helps support normal muscle and nervous system function • Thanks to vitamins B3, B6, B12 and C, it contributes to the reduction of tiredness and fatigue

Precisely stated content of all five electrolytes (sodium, chloride, potassium, magnesium, calcium) in milligrams per dose • Sodium (277 mg per dose) is, at the recommended dilution, close to the target concentration for replenishment during exercise • Magnesium and sodium are in citrate form, which is considered a well bioavailable organic salt • No added sugar and low energy value, suitable for use during activity itself • Coconut water powder as an additional natural source of electrolytes

Contains all five key electrolytes – sodium, chloride, potassium, magnesium and calcium – with precisely stated amounts in milligrams per dose • At the recommended dilution (2.5 g per 500 ml), it reaches a sodium concentration of around 700 mg per liter, which falls within the target range for replenishment during exercise • Magnesium and calcium are in citrate form, considered a well-absorbed organic salt • Free of sugar, flavorings, sweeteners and colorants • Gluten-free and lactose-free

Contains four key electrolytes – sodium, potassium, calcium, and magnesium – with amounts stated in milligrams • Provides a high dose of sodium (400 mg), which at the recommended dilution reaches a concentration close to the upper end of the target range for sweat replacement • Potassium (300 mg) supports normal muscle function • No added sugar • Among the most affordable products in this ingredient category
