Safety notes
- Magnesium: The NIH upper limit for magnesium from supplements is 350 mg a day for adults unless a doctor advises more; higher doses commonly cause diarrhea, and people with kidney disease are at higher risk of magnesium build-up.[NIH Office of Dietary Supplements]
- Magnesium: Magnesium can reduce absorption of some antibiotics and osteoporosis drugs, so doses are usually spaced apart.[NIH Office of Dietary Supplements]
Check interactions with a pharmacist before starting, and see a doctor about new or severe symptoms.
