SODIUM LOADING (PRE-HYDRATION)

A specialist pre-exercise strategy that combines sodium and fluid to increase fluid retention before a defined endurance demand.

Pre-exercise sodium can expand vascular fluid volume and a small evidence base suggests a possible endurance benefit in some conditions. Research does not establish one universal DIY dose, product or timing window. The decision should follow an individual sweat-loss and event review, be rehearsed, and account for health conditions or medication that make sodium and fluid manipulation relevant.
