Active Electrolyte Replacement
Every hard session costs you more than sweat — it costs you the minerals that keep your muscles firing and your body in balance. Electrolyte Rx replaces the essentials your body loses through activity, with a complete electrolyte profile that supports hydration, fluid balance and endurance from your first movement to your last. Rather than simply quenching thirst, it helps your body actually hold onto the water you drink, so you stay properly hydrated for longer, feel steadier through long or hot sessions, and give your muscles the mineral support they need to keep performing. It's the foundation the rest of the formula is built on — hydration done properly.
L-theanine for calm focus
Great performance isn't only physical — it's mental, and staying sharp under pressure is often what separates a good session from a great one. That's why Electrolyte Rx includes L-theanine, an amino acid valued for supporting a calm, clear state of focus without the jitters or crash of stimulants. It helps quiet the noise so you can lock in on the set, the split or the strategy in front of you, supporting steady concentration and mental clarity when it matters most. Hydration keeps your body in the game; L-theanine helps keep your mind right there with it.
Immune-supportive nutrients
Intense training doesn't only tax your muscles; it places real demand on your immune system, which is exactly when many athletes find themselves run down. Electrolyte Rx builds daily defence straight into your hydration, with immune-supportive nutrients including vitamin C, zinc and selenium woven through every serving. These micronutrients support your body's natural resilience and antioxidant defences, helping you recover from the stress of training and stay consistent through demanding weeks and changing seasons. Because the progress you make is only as good as the training you can actually show up for — and staying well is a performance advantage in its own right.
More kilometres. More sets. More time at your best. That's the power of proper hydration and energy replacement.
