Pregnancy creates increased nutritional needs in the body. The mother and the fetus require increased amount of micro and macro nutrients to survive through the demanding period of pregnancy.

Vitamin B12, otherwise called as cobalamin is crucial for maintaining a healthy nervous system. During pregnancy, it is believed that when it is combined with Folic acid supplements, it helps in thwarting off spina bifidia and other spinal and central nervous system disorders in your growing baby.

Vitamin B12 is found in fortified soy milk and other soy products, fish, egg, poultry and green leafy vegetables. Rather than taking supplements of it, consuming a wholesome diet rich in the vitamin is proved to be more beneficial.

Pregnancy is the most delicate and crucial period in a woman’s life. The surging hormones and the growing baby wrecks havoc in the expectant woman’s system. To support and nurture a new life, an expecting woman’s body requires an increased amount of micro and macro  nutrients.Although the old adage “eating for two” is not entirely true, but eating a wholesome food rich in essential nutrients is very much important to glide through the treacherous path of pregnancy and deliver a healthy baby.

Vitamin B12 is generally necessary for maintaining a healthy nervous system, but during pregnancy it becomes all the more important because it helps to put together the proteins that make up the physical body of the baby. When combined with Folic acid supplements, vitamin B12 or cobalamin helps in keeping spina bifidia and other spinal and central nervous system disorders in the baby at bay.

Benefits of vitamin B12 in the growing fetus:

  • It helps in the healthy development of the central nervous system. According to a study published in the journal Early human development, women who ate steak which is rich in vitamin B12 during the first trimester, gave birth to babies who cried eight times lesser than the babies born to women who had lesser vitamin B12 status during pregnancy. Scientists believe that this is due to the fact that, lack of vitamin B12 may reduce infant’s brain’s ability to produce the sleep harmone melatonin leading to sleeplessness.
  • Helps to make DNA, the genetic material in all the cells when combined with folate.
  • Aids in the formation of neural tubes of the fetus, brain and spine development
  • Promotes smooth functioning and development of brain, nerve, and blood cells in the growing baby.
  • Supports smooth functioning of the central nervous system and the neurological function by aiding the proper synthesis of myelin and fatty acids.
  • Boosts the energy levels, and elevates the mood and suppress stress levels by aiding the proper synthesis and balance of fats, carbohydrates and proteins in the expectant woman.

Effects of lack of vitamin B12 during pregnancy :

Deficiency of vitamin B12 can result in adverse pregnancy outcomes which can have lasting effects on both mother and child.

Miscarriage: Though many doctors say miscarriage and vitamin B12 deficiency are faintly related, many studies done recently prove otherwise. The experiments prove that 31% of women who lost their babies had high levels of homosystenine (an amino acid). Elevated homosystenine is caused due to the lack of folate, vitamin B12 and B6.

Neural tube defects in the baby: When mothers are deficient in B12 the damage to their babies start happening in the womb itself. When brain and spine are not formed properly, severe birth defects like neural tube defects and spina bifidia happens in the baby.

Preterm Birth: Vitamin B12 deficiency is also associated with increased risk of preterm birth and low birth weight in babies.

Anemia: Vitamin B12 is necessary for the body’s vital functions, including the production of red blood cells and cellular metabolic energy. B12 deficiency can cause anaemia and severe damage to the nervous system of the growing fetus .
