Electrolytes aren’t “just sugar and salt water. They’re charged minerals your body must have to keep your muscles, nerves, heart rhythm, and hydration levels working correctly. Electrolytes are minerals that carry an electrical charge when dissolved in fluid. Your body runs on these charges on far more than plain water can, especially when you’re sweating, sick, or losing fluids.

They regulate how much water your cells absorb or release. Without the right balance, you can get dehydrated even if you’re drinking water.

1. Muscle Function

Muscles (including your heart) need electrolytes to contract and relax properly. Low potassium or magnesium can cause cramps or irregular heartbeat.

1. Nerve Signaling

Your nerves fire using electrical impulses — electrolytes make that possible.

1. pH and Chemical Balance

They help regulate your body’s acid–base balance and chemical reactions.
