The context
Magnesium supports normal nerve, muscle and enzyme function, but the right product depends on the reason for using it—not the loudest claim on the bottle.
Buying checklist
- Compare elemental magnesium per serving, not only the compound weight.
- Check the serving size and total daily dose; more is not automatically better.
- Ask a clinician about kidney disease, medicines and persistent symptoms before supplementing.
Choose a clearly labeled product with realistic dosing and independent quality testing when available.
The practical takeaway
Choose a clearly labeled product with realistic dosing and independent quality testing when available.
