Magnesium is an essential mineral, but nutrient necessity does not mean that supplemental magnesium will treat a disease. Individual needs and safety depend on context.
How to read the research
Check the population studied, ingredient form, dose, duration, comparison group, outcome measured, and study size. A statistically significant finding is not automatically a meaningful result for every person.
Finished products are a separate question
Evidence about Magnesium alone does not prove that a multi-ingredient supplement containing it will produce the same outcome.
Safety
Check interactions, contraindications, and total intake from all products. If you take prescription medication or manage a diagnosed condition, discuss supplement use with a qualified healthcare professional.
