Are there risks from taking magnesium?

ANSWER

Magnesium supplements can cause nausea, cramps, and diarrhea. They often cause softening of stool.

Magnesium supplements may not be safe for people who take diuretics, heart medicines, or antibiotics.

People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their doctor.

At very high doses, magnesium can be fatal.

Check with doctor before taking magnesium.
