Why is Vitamin B12 Important for Fertility and Pregnancy?

Vitamin B12 (hydroxocobalamin and cyanocobalamin) regulates the normal functioning of the brain and nervous system. Among all kinds of vitamin B, this is the biggest one and functions as the center of the metabolism of the body cells.

Fertility problems constitute a major dilemma today, and vitamin B12 deficiency is among the chief causes of infertility in both genders. If one does not have enough vitamin B12 in their body, they can suffer from medical conditions such as memory loss, anemia, weakness, infertility, psychiatric and neurological disorders.

Vitamin B12 is also quite beneficial for conception and maintaining the babies’ fitness inside the mother’s womb.

What is the Need for Vitamin B12 During Pregnancy and for Fertility?

The spinal cord and brain of your baby need vitamin B12 for development and functioning. Vitamin B12 during pregnancy is equally important as it forms the healthy red blood cells in the fetus. This vitamin is used to create DNA which is the genetic material in the baby’s cells.

Studies and research pointing to the presence of a B12 vitamin deficiency in pregnant mothers have indicated a higher risk of neural tube defects in the baby. 

Vitamin B12 is needed for the production of healthy DNA and is also required for the decomposition of proteins and fats.

The required amounts of vitamin B12 should be reached for a correctly formed placenta and fetus and normal reproductive system functioning during pregnancy.

It is very much recommended that women planning to conceive should take enough amounts of vitamin B12 by including foods rich in this vitamin or through B12 supplements.

Most Viable Foods Rich in Vitamin B12 for Pregnancy

Vitamin B12 is only found in animal-based foods like fish, meat, poultry, dairy products, and eggs. Plant foods don’t have any vitamin B12 unless they’re fortified.

For a vegan looking for the best vitamin B12 source, breakfast cereals, with soy or other plant-based milk, is a good idea!

Food sources containing decent amounts of this vitamin include Atlantic Salmon, 2-percent milk, ground beef, plain fat-free yogurt, eggs, cheddar cheese, and turkey breast.

Vitamin B12 Deficiency During Pregnancy  

Vitamin B12 deficiency during pregnancy has its share of effects in both men and women, but in women, it primarily links to an increased risk of miscarriage, infertility, abnormal ovarian response, and neural tube defects in the growing fetus.

Vitamin B12 deficiency in pregnancy can also be the cause of reproductive problems which in turn can affect the fertility and the conception process.

A decrease in this vitamin further causes increased levels of homocysteine in the blood which has been also linked with pregnancy complications.

How Much of the Vitamin B12 is the Required Intake?

The advised amount of vitamin b12 intake depends mainly on a person’s age and sex. An adult’s recommended daily intake of vitamin B-12 is approximately 2.4 micrograms per day. Nevertheless, during pregnancy vitamin b12 intake should be higher than usual; and even when a woman is breastfeeding the need should be the same.

It has been established that a woman who is trying to conceive or going through the breastfeeding period should get enough amounts of vitamin B12 from her diet or through supplements to support her fertility and entire reproductive health.

Vitamin B12 recommended levels are also taken into consideration because vitamin B12 in excess may of course also be harmful to the baby as well as the mother.
