Sodium plays a crucial role in hydration by maintaining fluid balance in the body. It helps regulate blood pressure, supports nerve function, and ensures proper muscle contractions. By controlling the movement of water in and out of cells, sodium is essential for preventing dehydration and promoting optimal cellular function.

Potassium is vital for hydration as it works alongside sodium to maintain fluid and electrolyte balance. It aids in muscle function, nerve signaling, and helps regulate heartbeat. By ensuring proper cell function, potassium prevents cramping and supports overall hydration and energy levels.

Magnesium plays a key role in hydration by supporting cellular energy production and muscle function. It helps regulate fluid balance, aids in the absorption of other electrolytes, and reduces fatigue. Magnesium's role in over 300 biochemical reactions makes it essential for overall well-being and effective hydration.
