What it is
- Magnesium glycinate (bisglycinate) is magnesium bound to the amino acid glycine.[NIH Office of Dietary Supplements]
- Absorption studies have compared organic forms such as diglycinate with magnesium oxide.[PubMed][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.
