7 Potential Side Effects of Magnesium Citrate Supplements

Magnesium citrate is an absorbable form of magnesium used to manage occasional constipation due to its ability to improve bowel movements.

Although generally safe when used within the recommended limit of 350 mg, higher doses of magnesium citrate may cause gastrointestinal side effects.

Magnesium citrate increases water retention in the stool, leading to increased frequency of bowel movements and softer stools, making them easier to pass. Although this property is beneficial for people who want to treat constipation, it may not be suitable for others, as doses above 350 mg per day can increase the frequency of loose, watery stools.

Extremely high doses of magnesium citrate may cause more serious side effects, such as rectal bleeding (blood in the stool). Stop taking the medication immediately and consult your healthcare professional if you notice this side effect.

Magnesium citrate may also cause abdominal cramps or stomach pain, especially when taken in large doses. See your healthcare professional if abdominal cramps last more than two weeks.

• Talk to your doctor if you experience stomach pain, vomiting, or nausea lasting more than 2 weeks.
• Consider taking magnesium in the evening or when you are closer to the toilet.
