The Important Factor Of Vitamin D During Pregnancy

Vitamin D During Pregnancy

Importance Of Vitamin D In Pregnancy

Vitamin D supplements is essential during pregnancy to regulate calcium and phosphorus levels, vital for the development of your baby's bones and teeth, as well as maintaining healthy eyesight and skin. However, vitamin D deficiency is prevalent among pregnant women, potentially leading to issues like abnormal bone growth, fractures, or even rickets in newborns. Recommendations vary, with some suggesting 600 international units (IU) per day, while others advocate for higher doses ranging from 1,000 to 2,000 IU daily.

Furthermore, inadequate vitamin D levels have been linked to various pregnancy complications such as gestational diabetes, preeclampsia, preterm birth, and low birth weight, though further research is needed to confirm these associations. Symptoms of vitamin D deficiency can be subtle, including muscle pain, weakness, bone discomfort, and increased susceptibility to fractures. Additionally, deficiency can occur without noticeable symptoms, potentially impacting both maternal and fetal health if left unaddressed. While fatty fish and eggs are natural and the best sources for vitamin d for pregnancy, and certain foods are fortified with it, meeting the recommended intake solely through diet can be challenging during pregnancy.

Vitamin D Dietary Intake Needed For Pregnant And Nonpregnant Women

The recommended daily intake of vitamin D can vary depending on several factors, but here's a breakdown for pregnant and non-pregnant women:

For Pregnant Women

Pregnant Women: General Recommendation: 10 micrograms (400 International Units, IU) per day.


  • Some pregnant women might need more than 400 IU based on individual factors like sun exposure, diet, and blood test results.
  • Many prenatal vitamins include vitamin D, but the amount can vary. Check the label and discuss with your doctor if additional supplementation might be needed.

For Non-Pregnant Women

Age Groups: The recommended daily intake for non-pregnant women varies by age:

  • Age 19-50: 6 micrograms (200 IU) per day.
  • Age 51+: 8.5 micrograms (340 IU) per day


  • Similar to pregnant women, individual needs might be higher based on sun exposure, diet, and blood test results.
  • Certain health conditions may also influence vitamin D requirements.

Vitamin D Deficiency Risk Factor In Pregnancy

Several factors increase the likelihood of experiencing a vitamin D deficiency during pregnancy:

  • Conditions affecting fat absorption: Disorders like celiac disease and Crohn's disease diminish the body's ability to absorb dietary fat, consequently impeding the absorption of vitamin D.
  • Certain medications: Some medications, including steroids, antiseizure drugs, cholesterol-lowering medications, and specific diuretics, can interfere with the absorption of vitamin D from the intestines.
  • Darker skin: Higher melanin levels in darker skin act as a natural sunblock, limiting the synthesis of vitamin D in the skin.
  • Obesity: Increased body fat can sequester a significant portion of vitamin D produced in the skin, reducing its availability to the body.

If concerns arise regarding insufficient vitamin D intake, consulting with a healthcare provider is advisable to discuss potential testing for deficiency or the necessity of a vitamin D supplement. When selecting a dietary supplement, opt for vitamin D3, also known as cholecalciferol, as it is the most effective form.
