Stamina Rx — Endurance Energy & Electrolyte Fuel
Electrolytes and low-GI energy replacement — hydration and endurance fuelling built for the long haul.
Built for the two things that end endurance performance: electrolyte depletion + energy depletion
Palatinose™ low-GI carbohydrates — steady fuel and improved fat oxidation
A balanced electrolyte + mineral blend maintains hydration and muscle function
BCAA-rich amino complex + built-in lactic-acid buffer + vitamin C
Description
Endurance isn’t just fitness. It’s fuelling — and most athletes get it wrong.
Hitting the wall halfway through every long session? Your fuel ran out before you did. Stamina Rx addresses the two factors that end endurance performance: electrolyte depletion and energy depletion.
Palatinose™ low-GI carbohydrates release energy steadily and support improved fat oxidation, while a balanced electrolyte profile maintains hydration and muscle function. A BCAA-rich amino complex and a built-in lactic-acid buffer keep you going when others fade.

Stamina Rx — Endurance Energy & Electrolyte Fuel
For Balanced Energy Supply
Reduce Lactic Acid Buildup with an electrolyte, endurance drink
Endurance performance ultimately comes down to two key factors: energy availability and hydration status. As carbohydrate stores drop and electrolytes are lost through sweat, fatigue increases and performance declines — regardless of fitness level. Stamina Rx is formulated to support both simultaneously with sustained-release carbohydrates for balanced energy, a carefully balanced electrolyte blend to support muscle function and hydration, and a built-in buffering system designed to help manage lactic acid buildup during intense exercise. The result is genuine, scientifically informed endurance support, not just sugar, colour and flavouring.

Protein Rx — All-In-One Protein Shake
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.
FAQs
Please read our FAQs page to find out more.
What is Stamina Rx used for?
Stamina Rx is a premium energy and electrolyte drink designed to optimise hydration, improve endurance, and support peak performance during intense physical activity.
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?
Start sipping 10–15 minutes before your workout or event. Continue during activity by consuming 500–750 ml per hour for moderate intensity, or up to 1000 ml per hour for high-intensity training.
How do I use Stamina Rx?
Mix 40 g (around 4 level scoops) with 500 ml of cold water in a shaker or water bottle. Shake well to dissolve. Adjust serving based on intensity and duration of activity.
What makes Stamina Rx different from other hydration drinks?
It features a unique blend of Palatinose™️ low GI carbohydrates, a complete electrolyte and mineral profile, amino acids, and a lactic acid buffer — all working together to sustain energy, reduce muscle fatigue, and promote recovery.
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.
Does Stamina Rx help with recovery?
Yes. It contains BCAAs and vitamin C, which help reduce muscle breakdown, combat exercise-induced inflammation, and support faster recovery.
Can I take Stamina Rx with other supplements?
Yes, STAMINA Rx can be taken alongside most fitness and wellness supplements. If unsure, consult your fitness or healthcare professional.
Is Stamina Rx suitable for daily use?
It’s formulated for use around training or endurance events, but may be used daily if you have an active lifestyle or elevated hydration needs.
Does Stamina Rx contain caffeine?
No, Stamina Rx is caffeine-free and relies on nutritional ingredients to fuel performance without the crash.
Are Sport Rx products safe for professional athletes?
SPORT Rx is SA's first clean label brand. Our blends use 100% natural ingredients which are safe for athletes and contain no artificial or prohibited substances.
How should I store this product?
Store in a cool, dry place and keep the pack tightly sealed after each use to maintain freshness.
