Active Electrolyte Replacement
As sweat losses accumulate during exercise, the depletion of key electrolytes — particularly sodium and potassium — disrupts the osmotic balance that regulates fluid movement in and out of muscle cells. This contributes to fatigue, cramping, impaired neuromuscular function and ultimately reduced performance.
Stamina Rx's electrolyte profile is designed to actively replace these losses during exercise, maintaining the internal environment the body needs to sustain output across extended training periods.
Energy Replacement for Extended Endurance
The body's glycogen stores — the primary fuel source for moderate to high-intensity exercise — are limited and become increasingly depleted during sessions lasting more than 60-90 minutes. Consuming readily available carbohydrates during extended activities provides an additional fuel source that spares glycogen, delays fatigue and allows athletes to maintain a higher intensity for longer. This function is what Stamina Rx's energy component is designed to serve.
Clean Formulation — Beyond the Mainstream Sports Drink
Most commercially available sports drinks are dominated by excessive sugar, artificial colours and synthetic flavouring. Stamina Rx offers meaningful performance support without these unnecessary inclusions — because Sport Rx's athletes don't need a product that looks impressive; they need one that performs. The clean formulation reflects the same label transparency that applies across the entire Sport Rx product range.
More kilometres. More sets. More time at your best. That's the power of proper hydration and energy replacement.

Who is this product designed for?
It’s ideal for endurance athletes, high-intensity trainers, and anyone needing sustained energy, hydration, and recovery support before, during or after exercise.
When should I take Stamina Rx?

What makes Stamina Rx different from other hydration drinks?

What is palatinose and why is it important?
Palatinose™️is a low GI carbohydrate that provides steady, long-lasting energy and supports improved fat oxidation during endurance activity — unlike the spikes and crashes from high GI sugars.
