Electrolytes
Minerals such as sodium, potassium, and magnesium that maintain hydration; adequate intake can blunt false hunger driven by dehydration.
Benefits
Replace sodium, potassium, and magnesium lost through sweat or illness, supporting hydration, nerve, and muscle function.
Risks
Excess sodium raises blood pressure, and in kidney disease potassium overload can be dangerous. Most people meet their needs from food without supplements.
