What it is
- Magnesium forms differ in how much is absorbed; one randomized study found magnesium citrate more bioavailable than oxide.[PubMed]
- Diarrhea is the classic side effect of high-dose magnesium salts; owners often describe glycinate as milder on the bowel.[NIH Office of Dietary Supplements]
Safety and interactions
- The NIH upper limit for supplemental magnesium is 350 mg a day for adults unless a doctor advises more.[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.
