Magnesium for children: nutritional needs differ from sleep and mood treatment

Children need magnesium for normal growth and physiological function, but that does not establish extra magnesium as a general sleep or mood treatment. Age, diet, medical history and the intended outcome matter. Adult doses and adult research should not simply be transferred to children.

Is magnesium chloride dangerous? Dose, route and kidney function matter

Magnesium chloride is used in some supplements and external products; its name alone does not make every use safe or dangerous. Excess oral magnesium can cause gastrointestinal effects and serious toxicity, particularly with impaired kidneys. An external-use spray is not an oral supplement.
