Ensure you’re getting enough magnesium during pregnancyFertility
By Monya De, MD MPH
When I was a medical student, “magging” was a popular activity in the obstetrics ward. “Magging” referred to injecting magnesium sulfate into the IVs of laboring women. Magnesium slows down contractions and reduces blood pressure in women suffering from pre-eclampsia, the old “toxemia of pregnancy,” also referred to as “pregnancy-induced hypertension.”
Magnesium was certainly effective in the hospital. But did you know that magnesium can be helpful in pregnancy in many ways?
A few examples include:
- Improving learning and memory. Researchers gave magnesium to rats who had been exposed to an inflammatory substance; offspring of the magnesium group had fewer problems with learning and memory.
- Protecting the brains of preterm babies from strokes and other adverse events. Severely preterm babies, though, still suffer from intellectual deficits and other problems, despite the magnesium.
- Successful pregnancy with Gitelman’s syndrome. In Gitelman’s syndrome, the kidney “dumps” magnesium, which leads to miscarriage unless the mother takes large quantities of magnesium.
Note that several of these studies used IV magnesium, so we can’t say exactly how much magnesium is effective for these outcomes in the oral form. Be safe and ask your doctor how much magnesium you can take while pregnant, and always know what is in your supplements! You can also test your magnesium levels and proactively identify deficiencies.
