It is important to consult with a healthcare professional before taking any supplements, including magnesium. Unless prescribed by a doctor for a specific reason, taking magnesium supplements may not be necessary or recommended for everyone. It is also important to be cautious if you have kidney issues, as magnesium can potentially cause serious heart problems if it accumulates in the body. If you do choose to take magnesium, it is possible to open the capsule and sprinkle the powder on your food for easier consumption.
