Electrolyte

Electrolytes are minerals that carry an electrical charge when they are dissolved in water or body fluids. MedlinePlus says they help balance the water in your body and support muscle and nerve function.

Sweat carries away water and salts together. That is why plain water alone may not cover a long, hot shift. NIOSH advises sports drinks with balanced electrolytes when sweating lasts several hours. The main electrolytes are sodium, potassium and magnesium. Read our electrolytes 101 guide for the basics. Rapid Restoration Drops are a liquid dietary supplement that replaces electrolytes lost in sweat.
