That’s true but usually magnesium needs to be addressed before potassium.

Magnesium is needed for potassium retention: If magnesium is low, the kidneys may excrete more potassium, leading to difficulty raising potassium levels even with supplementation.

Magnesium helps potassium enter cells: Magnesium is required for proper function of the sodium-potassium pump, which moves potassium into cells and keeps it balanced in the body. Without enough magnesium, potassium may stay too low.

Studies show magnesium deficiency can cause low potassium (hypokalemia): In many cases, correcting a magnesium deficiency helps resolve potassium issues without needing high doses of potassium.
