Most electrolyte products are designed for daily rehydration rather than post-workout recovery. However, there is a significant difference between the electrolyte needs after sweating and those of everyday hydration. In fact, many products marketed as sports-focused contain electrolyte levels that are only suitable for general hydration.

HYIA is formulated based on scientific research conducted on athletes and individuals who engage in physical activity, typically lasting around one hour. We have consulted numerous studies to determine the optimal and scientifically proven levels of electrolytes required for effective post-sweat rehydration. Our formulation includes only ingredients that have been scientifically validated to support hydration, ensuring no unnecessary additives are included.

Why HYIA

  • Journal of the International Society of Sports Nutrition (2016)

    Findings: Drinks containing sodium levels greater than 600mg per litre and less than 1000 mg per litre enhanced fluid retention and electrolyte balance better than those with lower sodium concentrations. The study showed that the higher sodium content improved plasma volume recovery and decreased urine output, which are key for effective rehydration

    Conclusion: For athletes experiencing moderate to heavy sweat loss, between 600 - 800 mg of sodium in post-exercise hydration is advisable to maximize recovery

  • Nutrients (2020)

    Research from Nutrients (2020) compared high-potassium beverages with sugar water after exercise-induced dehydration

    Findings: Drinks containing potassium, alongside sodium, are important for rehydration after exercise because it aids in fluid retention and replenishes lost electrolytes

    Conclusion: This study highlights that potassium is essential for rehydration as it helps restore hydration and may benefit muscle function

  • Journal of the International Society of Sports Nutrition (2021)

    Research from the Journal of the International Society of Sports Nutrition (2021) compared rehydration solutions containing magnesium vs spring water intake during exercise in the heat on muscle cramps 

    Findings: When drunk during exercise, drinks containing magnesium decreased muscle cramp susceptibility

    Conclusion: Those looking to reduce muscle cramps while exercising should consider a magnesium containing beverage over plain water 

  • National Institutes of Health (NIH)

    Research at the National Institutes of Health (NIH) tested electrolyte drinks compared to water in analyzing post exercise rehydration in athletes

    Findings: Drinks containing electrolytes promoted greater rehydration than water when consumed early post exercise

    Conclusion: Athletes who are looking for optimal rehydration should consider a rehydration solution over water shortly after exercise
