Electrolytes for Ultra Athletes

Extreme Hydration for Extreme Performance

When you're pushing past the limits of endurance, you need hydration that works as hard as you do. LYTES offers a specialised range of ultra athlete electrolytes designed to support stamina, performance, and full-body recovery during the most demanding events and training.

From ultramarathons to Ironman triathlons and multi-day mountain races, these sugar-free electrolyte powders, capsules, and sachets provide critical levels of sodium, potassium, magnesium, and chloride—the essential minerals lost during extreme physical exertion.

Why Ultra Athletes Trust LYTES Electrolytes

  • 🏔️ Built for ultrarunning, Ironman, endurance cycling, and adventure racing

  • 💧 Supports hydration, muscle endurance & electrolyte balance

  • 🧪 Zero sugar, zero fillers – keto, fasting & low-carb compatible

  • 🥤 Convenient formats for on-the-go fuelling & aid station refills

  • 🇬🇧 Free Royal Mail tracked shipping across the UK

  • 🏆 Featuring elite-level brands: LMNT, Redmond Re-Lyte, Keto Chow, and more

When your event lasts hours—or even days—don’t let electrolyte loss be your weak link. Hydrate the LYTES way.
