The brain is like a high-speed network, constantly sending messages using tiny electrical impulses. For these messages to travel smoothly, the body relies on potassium and magnesium. Potassium acts like a messenger, helping electrical signals pass between nerve cells efficiently, keeping thoughts sharp and reactions quick. Meanwhile, magnesium works as a stabilizer, preventing overstimulation of the brain. This balance supports better memory, concentration, and cognitive development, making learning easier and helping kids stay focused in school.
