What it is
- Magnesium is a mineral the body uses in hundreds of enzyme reactions. Supplements come in many forms (oxide, citrate, glycinate and others) that differ in how much magnesium they contain and how well it is absorbed.[NIH Office of Dietary Supplements]
- A 2017 systematic review found the evidence on magnesium and subjective anxiety suggestive but of poor quality.[PubMed]
Safety and interactions
- The NIH upper limit for magnesium from supplements is 350 mg a day for adults; higher doses commonly cause diarrhea, nausea and abdominal cramping.[NIH Office of Dietary Supplements]
- Magnesium can reduce the absorption of some antibiotics (tetracyclines, quinolones) and bisphosphonates, so the NIH advises spacing the doses apart.[NIH Office of Dietary Supplements]
Supplements can interact with medicines. Talk to a doctor or pharmacist first, especially if you are pregnant, take prescription medicine, or have red-flag symptoms. See supplement safety and interactions.
