Who This Is For

The Hydration & Cramp Control Bundle is designed for runners who:

  • Sweat heavily or train in warm or humid conditions
  • Run long distances
  • Experience muscle tightness or cramping during or after runs
  • Want to separate hydration from fuelling
  • Prefer a simple, repeatable hydration strategy

How to Use

Use this bundle to support hydration during runs and muscle function across your training week.

  • Sustain Electrolytes:
    Mix one serving with water and sip before or during runs, especially in warm conditions
  • Power Up Magnesium:
    Take daily, ideally in the evening, to support muscle relaxation and recovery

Adjust intake based on sweat rate, temperature, and training intensity.

Why This Bundle Exists

Hydration and cramping issues are rarely caused by a single factor.

This bundle exists to support runners with a balanced, evidence-led approach — replacing electrolytes lost in sweat while also supporting normal muscle function — without relying on sugar-heavy drinks or complicated protocols.

Simple tools for challenging conditions.
