During pregnancy, it is necessary to have vitamin C (also referred as ascorbic acid) in right amounts in the body. It is essential for the:

  1. It helps the body absorb iron from food (mostly vegetarian sources). Iron keeps hemoglobin levels normal and protects you from anemia. Iron rich food along with a glass of orange juice aids better absorption (5) of the mineral. Vitamin C increases the iron absorption from the intestines.

It helps in the formation of baby’s tissues, strengthens the blood vessels of the placenta, thereby providing more oxygen to the fetus, and lowers the risk of placental abruptioniXA pregnancy complication characterized by the detachment of the placenta from the uterus before delivery, causing severe complications (7). Placental abruption is prevented by vitamin C by improving adhesiveness of the placenta.
  1. It is also an excellent remedy for constipation and is useful for easy bowel movements (8).

She says, “I continued to take vitamin C before I became pregnant this last time and throughout my last pregnancy. I am still taking it now. Throughout this time, I noticed that the stretch marks from my first pregnancy continued to reduce. Although I did get some new stretch marks from this recent pregnancy, they were much less pronounced than the ones from the first one (i).”

Vitamin C foods can be divided into various categories:

Fruits – It is found in citrus fruits like orange, lemon, and tangerine and also in apples, apricots, persimmons, peaches and berries such as strawberries, sea buckthorn and blackcurrant. They can be taken fresh or also in the juice or compote forms.

Green leaves – Parsley and sorrel are excellent sources.

Animal sources – Both meat and fish have enough amount of ascorbic acid to help meet your daily requirement.

Briar (thorny bush) – It can be brewed and taken in tea form. It tastes good when mixed with honey.

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.
  1. It will also cause bleeding gums, which disrupt the capillary veins (small blood vessels) beneath the skin. If this condition persists, it may cause scurvy.
  1. Deficiency in vitamin C can also cause rough and dry skin, and slow the healing of cuts, bruises and brittle hair.

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 (11).
  • 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, insomniaiXA sleep disorder that makes it difficult for one to fall asleep, stay asleep, or get a sound sleep , 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 hypertensive disorders and gestational diabetes, and diabetic women will experience a spike in their blood sugar levels. According to the US Centers for Disease Control and Prevention (CDC), 2 to 10% of pregnant women are affected by gestational diabetes yearly in the US. Also, the delivery hospitalizations due to hypertensive disorders in the US increased from 13.3% to 15.9%, noted CDC’s Morbidity and Mortality Weekly Report (MMWR) 2017-2019. Thus, taking the necessary precautions to avoid such complications for the mother and the baby and having a healthy pregnancy is important.

  • A few reports say that intake of excessive vitamin C supplements prevents scurvy, a disorder associated with vitamin C deficiency (12). 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 and hampering infant health.

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