What are electrolytes for?

Electrolytes are essential for maintaining brain and body health. According to Andrew Huberman, every cell in your brain and body relies on having enough electrolytes, such as sodium, potassium, and magnesium, to function properly. This is particularly crucial for neurons, or nerve cells, which need sufficient amounts of these electrolytes, especially sodium and potassium, to fire action potentials, the electrical signals that allow you to think, feel, and move 1.

Proper hydration and electrolyte balance are crucial, especially if you exercise a lot, sweat heavily, or fail to consume enough water and electrolytes through foods and liquids throughout the day 1.
