Vitamin C Deficiency During Pregnancy:

Deficiency of vitamin C will lead to major complications in both the mother and baby.

  1. Vitamin C deficiency prevents the fetus’ brain from optimal development. According to a study conducted at the University of Copenhagen, pregnant women should make sure to include vitamin C in their diet from the beginning because taking it after the damage is done to the baby’s brain will not help. The study has found that fetal brain damage could happen very early in the pregnancy.

Do You Need Vitamin C Supplements During Pregnancy?

It is quite easy to get the daily requirement of vitamin C from foods. Therefore, most pregnant women do not need supplements. A glass of orange juice (especially calcium-fortified) during breakfast helps you get the required amount.

Research shows that vitamin C supplementation helps prevent premature rupture of choriomaniotic membranes (PROM) (11).

It is advisable to talk to your healthcare provider before taking any supplements containing vitamin C as they can risk premature labor.

Side Effects Of Excess Vitamin C:

  • The vitamin C intake should not exceed the recommended daily allowance, especially during pregnancy. It may lead to the following complications if taken in excess amounts.
  • Continuous consumption of vitamin C above two grams every day can aggravate gout condition and develop kidney stones (12).
  • Women who are highly dependent on a high dosage of vitamin C may show its deficiency symptoms when they abruptly stop taking vitamin C. It is advisable to cut down the amounts gradually.
  • High doses of vitamin C will lead to abdominal cramps, nausea, fatigue, gut blockage, insomnia, headaches, diarrhea, hot flashes and rashes.
  • Advanced side effects include inflammation of the esophagus, Parkinson’s disease, red blood cell complications, discomfort at the injection site, thickened blood vessels around heart, skin irritation, problems of digestive tract and urinary tract complications.
  • It may increase the risk of high blood pressure, and diabetic women will experience a spike in their blood sugar levels.
  • A few reports say that intake of excessive vitamin C supplements prevents scurvy, a disorder associated with vitamin C deficiency (13). But again according to the American Pregnancy Association, too much of vitamin C taken when pregnant can cause newborn scurvy (baby will be born with vitamin C deficiency). When you take more, your kidneys will excrete the excess amount of vitamin C, thus causing resistance or intolerance to it in your baby.

Diuresis (increased production of urine) and excess fluid intake helps rule out some of the above conditions.
