Electrolytes

A hydration category where sodium, potassium, kidney context, blood-pressure context, and workout losses matter more than generic hydration language.

Practical read

Use electrolyte timing around actual fluid and sweat context. Daily high-potassium or high-sodium products deserve a medication and kidney-context review first.
