Electrolytes and Migraine: Sodium, Potassium, Magnesium
Electrolytes support normal body function, but a migraine attack does not by itself mean you need extra sodium, potassium or an electrolyte drink. Replacing losses from illness or prolonged sweating is a different question from choosing a migraine preventive treatment. Magnesium has some migraine prevention evidence; that does not establish that any electrolyte blend will prevent or stop an attack.
The useful first question is what problem you are trying to solve. A product for fluid replacement, a prescribed treatment for a measured imbalance and a supplement trial for migraine have different purposes. Their labels may use similar language while offering very different amounts and ingredients.
