What is magnesium?

Magnesium is a vital element required for more than 300 bodily functions. It is crucial for the production of body proteins, DNA, muscle and neuron activity, bone development, blood pressure regulation, and blood sugar management.

What are the benefits of magnesium during pregnancy?

Magnesium helps to relax muscles, control body temperature, maintain appropriate blood sugar levels, and contribute to the development of strong bones and teeth. Additionally, it controls heart rate and cholesterol. Furthermore, it can promote deeper sleep and support mood stabilization.

There is evidence that magnesium helps to lessen discomfort, and muscular, and leg cramps. The congestion of the intestines brought on by carrying a baby within the body might cause constipation and digestive problems. Periodic constipation can be treated with magnesium, resulting in simpler and more frequent bowel motions.

A reduction in the likelihood of high blood pressure, heart disease, preeclampsia, placental malfunction, premature labor, and low birth weight are some effects.

  • Reduces nausea: Along with morning sickness, nausea is the most prevalent illness that may be treated with magnesium.
  • Reduces risk of cerebral palsy: A review written in Australia found that giving magnesium sulphate to pregnant women at risk for preterm labour reduced the likelihood that their offspring would have cerebral palsy.
