Women need vitamin C in pregnancy as it offers following benefits:

  • help in iron absorption
  • offer antioxidants
  • maintain healthy bones, cartilage, blood vessels and skin
  • promote healthy collagen formation
  • and aid the development of the placenta and baby.

What Is the Simple Definition of Vitamin C?

Vitamin C is a water-soluble vitamin, which means your body cannot store it for long periods.

It is also known as ascorbic acid and dehydroascorbic acid.

It is an essential vitamin.

Essential vitamins are nutrients that your body cannot make, so an individual needs to get vitamin C from other sources.

You need a regular supply through your diet or supplements if recommended by your doctor. The recommended daily intake during pregnancy is around 85 mg/day (varies slightly by country).

Why Is Vitamin C So Important in Pregnancy?

Because ascorbic acid offers the following benefits:

1. Improve the absorption of non-heme iron

Iron deficiency is one of the most common nutritional deficiencies during pregnancy and can have major impacts on both maternal and fetal health.

That's why adequate vitamin C intake is necessary, as it helps improve the absorption of non-heme iron (the type found in spinach, lentils, beans, and vegetables). This becomes especially crucial for women eating only plant-based diets.

Experts recommend combining spinach with the following for better results:

  • Lemon juice
  • Orange slices
  • Tomatoes
  • Bell peppers

2. Contributes to healthy placental development

Studies show that vitamin C contributes to the formation of collagen (the primary building block of your body's skin, muscles, bones, etc.) and development of healthy blood vessels within the placenta. 

3. Supports baby's growth & development

Vitamin C helps produce collagen, which means it helps support development of

  • Bones
  • Cartilage
  • Skin
  • Blood vessels
  • Connective tissues

4. Helps immune system to function in healthy manner

During pregnancy, there is the change in the functioning of the immune system.

Vitamin C supports your immune system to function in a balanced manner. It acts as an antioxidant to safeguard healthy cells from oxidative stress (too many unstable molecules).

5. May lower oxidative stress

Oxidative stress is an imbalance of free radicals (highly reactive and unstable oxygen molecules) and antioxidants in your body that leads to cell damage.

Vitamin C acts as an antioxidant, which helps protect cells from molecular damage and lower oxidative stress.

6. Contributes to healthy skin & wound healing

Vitamin C helps in collagen production, therefore improving:

  • Skin elasticity and tissue repair
  • Wound healing after delivery
  • Healthy blood vessels
