Magnesium Citramate is a nutritional supplement designed to treat magnesium deficiency. It provides magnesium bound to citrate-malate. Magnesium is an essential nutrient that helps your heart and lungs function normally and aids in proper metabolism of carbohydrates. This supplement is distributed by Thorne Research and is available over the counter. Before using this form of magnesium, you should be aware of its side effects.

Bloating or Gas

After taking a dose of Magnesium Citramate, you may experience abdominal bloating or gas, according to Thorne Research. Gassiness can be uncomfortable and may cause your clothing to feel unusually tight around your midsection. If excess gas or bloating is bothersome, contact your doctor for guidance.


Treatment with this Magnesium Citramate may cause diarrhea as a side effect, Drugs.com warns. Diarrhea typically results in urgent or frequent bowel movements that yield runny, loose stools. If you develop diarrhea, you may also experience abdominal cramping, pain or bloating. Persistent or chronic diarrhea should be discussed with a medical professional, as this side effect may result in dehydration. You should also seek medical care if you develop dark or black stools or notice blood within your stools, which may be signs of internal bleeding.

Allergic Reaction

If you are allergic to magnesium or any of the ingredients in Magnesium Citramate, you should not take this supplement. Improper use by hypersensitive people may cause a severe allergic reaction. Seek emergency medical care if you develop symptoms of an allergic reaction, such as hives, oral swelling, pale skin, dizziness, weakness or breathing difficulties after taking a dose of this supplement.
