Pregnancy is a magical and transformative time in a woman’s life, but it also comes with its unique challenges.

Additionally, magnesium deficiency during pregnancy can exacerbate these symptoms and pose potential risks to both the mother and the baby. In this blog post, we will delve into the crucial topic of magnesium deficiency and its impact on morning sickness during pregnancy. We will explore the symptoms of low magnesium, the role of magnesium in alleviating nausea, safe magnesium supplementation during pregnancy, the potential risks of excessive magnesium intake, the benefits of maintaining adequate magnesium levels, and recommended magnesium oil products for pregnancy.

Symptoms of Low Magnesium in Pregnancy

Magnesium is a vital mineral that plays a crucial role in various bodily functions, including nerve function, muscle contractions, and regulating blood pressure. During pregnancy, a woman’s magnesium needs increase to support the developing fetus. However, due to inadequate dietary intake or other factors, magnesium deficiency can occur, leading to various symptoms. Some common symptoms of low magnesium during pregnancy include:

  1. Muscle cramps and spasms: Pregnant women with magnesium deficiency may experience painful muscle cramps, particularly in the legs.
  2. Fatigue and weakness: Low magnesium levels can contribute to general feelings of fatigue and weakness, which can be especially challenging during pregnancy.
  3. Nausea and vomiting: Morning sickness is a common pregnancy symptom, but magnesium deficiency may exacerbate these symptoms.
  4. Mood swings and anxiety: Magnesium plays a role in regulating neurotransmitters, and insufficient levels can lead to mood disturbances and increased anxiety.
  5. Insomnia: Sleep disturbances, including insomnia, can be associated with magnesium deficiency in pregnancy.

Does Magnesium Help with Nausea During Pregnancy?

One of the most pressing concerns for pregnant women is managing morning sickness, which can occur at any time of day. While there are various remedies available, magnesium has shown promise in helping to alleviate nausea during pregnancy. Magnesium helps to relax the muscles in the gastrointestinal tract, which may reduce the intensity and frequency of nausea and vomiting. Additionally, magnesium’s role in stabilizing blood sugar levels can also contribute to the reduction of morning sickness symptoms.

Best Magnesium Supplement for Pregnancy

If you suspect you have a magnesium deficiency or are experiencing morning sickness, it’s essential to consider safe and effective magnesium supplementation. However, before starting any supplement regimen during pregnancy, it’s crucial to consult with a healthcare provider to ensure it’s appropriate for your individual needs. Some safe and commonly used magnesium supplements during pregnancy include:

  1. Magnesium Glycinate: This form of magnesium is gentle on the stomach and easily absorbed, making it an excellent choice for pregnant women.
  2. Magnesium Citrate: Magnesium citrate is also well-absorbed and can help with constipation, which is another common issue during pregnancy.
  3. Magnesium L- Threonate: This form of magnesium is known for its ability to cross the blood-brain barrier and support cognitive function, which can be beneficial for expectant mothers.
Is 500mg of Magnesium Safe During Pregnancy?

The appropriate dosage of magnesium during pregnancy can vary from woman to woman, depending on individual needs and medical history. While the recommended dietary allowance (RDA) for magnesium during pregnancy is around 350-400mg per day, some healthcare providers may suggest higher doses in certain cases. However, it’s essential to avoid self-prescribing high doses, as excessive magnesium intake can lead to adverse effects.

Too Much Magnesium During Pregnancy

As with any supplement, consuming too much magnesium during pregnancy can have adverse effects. Excessive magnesium intake can lead to diarrhea, abdominal cramps, and dehydration, which can be particularly dangerous during pregnancy.

Benefits of Magnesium During Pregnancy

Maintaining adequate magnesium levels during pregnancy offers numerous benefits for both the expectant mother and the developing baby. Some of the key advantages include:

  1. Reduced risk of preterm labor: Magnesium supplementation has been associated with a lower risk of preterm labor in some studies.
  2. Enhanced bone health: Magnesium plays a vital role in bone development, which is crucial for the growing baby.
  3. Lowered risk of preeclampsia: Some research suggests that adequate magnesium intake may help reduce the risk of developing preeclampsia, a serious pregnancy complication.
  4. Improved sleep quality: Magnesium’s relaxation properties may contribute to better sleep quality for expectant mothers.

Best Magnesium Oil for Pregnancy

Magnesium oil, a topical magnesium supplement applied to the skin, can be a convenient way for pregnant women to boost their magnesium levels. It is easily absorbed through the skin and can help alleviate muscle cramps and tension. However, it’s essential to choose a high-quality and safe magnesium oil product. Always look for products that are free from harmful additives and chemicals. Additionally, consult with your healthcare provider before using any new supplement, including magnesium oil, during pregnancy.

Magnesium Spray Pregnancy NHS

While it’s essential to consult with your healthcare provider for personalized advice, some NHS resources may offer information on the benefits and safety of magnesium supplementation during pregnancy. Pregnant women interested in using magnesium spray should check NHS-approved sources for relevant guidelines and recommendations.


In conclusion, magnesium deficiency during pregnancy can exacerbate morning sickness and pose potential risks to both the mother and the baby. Adequate magnesium intake is vital for promoting a healthy pregnancy and alleviating morning sickness symptoms. However, it’s crucial to work with a qualified healthcare provider to determine the appropriate magnesium supplementation based on individual needs and medical history. By prioritizing your health and seeking professional guidance, you can ensure a smooth and joyful pregnancy journey for both you and your baby.
