Description

Each sachet delivers a balanced electrolyte profile with 500mg of sodium, 200mg of potassium and 20mg of marine magnesium. This formula supports rapid fluid absorption, nerve and muscle function, and overall electrolyte balance to help reduce cramping and maintain performance throughout long efforts. The added grapefruit flavour keeps it light and refreshing when it matters most.

What sets Race 500 apart is its targeted 2:1 energy blend: 200mg L-theanine and 100mg caffeine. Together, they offer the performance-enhancing benefits of caffeine, improved alertness, mood and reaction time, without the usual jitters. L-theanine works to calm the nervous system, helping maintain focus and clarity even during high-intensity moments.

Vegan-friendly and easy to mix with 500ml to 1L of water, Race 500 is your go-to formula when you need more than just hydration. It’s about staying cool, composed, and ready to perform, right to the finish line.

How does it work

Race 500 works by combining a clinically supported electrolyte profile with a precise blend of caffeine and L-theanine. Sodium enhances water absorption in the gut, potassium and magnesium support muscle and nerve function, and the 2:1 caffeine-to-L-theanine ratio delivers smooth, sustained energy without the crash. This dual-action approach ensures hydration and mental focus are maintained, even under race-day pressure.

The caffeine increases alertness and reduces fatigue, while L-theanine tempers its intensity by reducing stress responses and sharpening mental clarity, making it a powerful combo for sustained performance.
