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.
