Have you been tested for vitamin B12 deficiency during pregnancy? If not, you should. If you have vitamin B12 deficiency or pernicious anemia, you can still have a normal pregnancy and give birth to a happy, healthy baby. Here are some crucial facts about vitamin B12 deficiency and pregnancy.
Vitamin B12- What is it?
Vitamin B12 (cobalamin) is an essential B-vitamin that occurs naturally in animal-based foods: beef, chicken, halibut, crabmeat, clams, and Swiss cheese are among the richest food sources of vitamin B12.
Your body (and your baby) needs vitamin B12 for many vital functions:
- Red blood cell production
- Protection of the nerve cells
- Cognitive functioning
- Bone health
- DNA synthesis
- Homocysteine control
- Energy production
What are the symptoms of vitamin B12 deficiency?
The following symptoms may indicate the beginning of vitamin B12 deficiency:
- Fatigue in the morning after sleeping the whole night- this is because your brain is not getting enough oxygen

- Painful tingling in the arms, hands, feet, legs, and tongue- this is a sign of neurological damage

Am I at risk for vitamin B12 deficiency?
Most healthy people who eat foods rich in vitamin B12 don’t have to worry about becoming deficient. Still, vitamin B12 malabsorption is the leading nutritional deficiency, and that percentage is climbing, so it’s worth understanding the risk factor involved.
People who are at risk for vitamin B12 deficiency include:
- People with pernicious anemia, an autoimmune disorder involving the inability to make intrinsic factor, a necessary hormone for absorbing vitamin B12
- Anybody who has had gastric bypass surgery
- Anybody who has had the ileum removed through gastrointestinal surgery
- Diabetics who take metformin
- People taking protein pump inhibitors (PPIs) for GERD
- People with illnesses or conditions that affect the digestive system, such as celiac disease, Crohn’s disease, fibromyalgia, ulcerative colitis, migraines, chronic fatigue syndrome, autism, food allergies, or irritable bowel syndrome (IBS)
- Elderly individuals
Don’t I get enough B12 from prenatal vitamins?
Yes and no. If your stomach is able to manufacture intrinsic factor and thus digest vitamin B12, then you probably get the bare minimum dosage from prenatal vitamin supplements.
However, if you have pernicious anemia, or if you suffer from a gastrointestinal disorder, then it doesn’t matter how many vitamin B12 pills you swallow; all dietary sources of vitamin B12 are indigestible. Without intrinsic factor, your body cannot access vitamin B12 unless it is inserted directly into the bloodstream.

Get tested for B12 deficiency
Before you start planning a family, get tested for vitamin B12 deficiency. Unfortunately, most physicians don’t automatically check for vitamin B12 deficiency, so you’ll need to request a B12 blood screening.
If you are diagnosed with vitamin B12 deficiency or pernicious anemia, then your doctor will most likely prescribe routine rounds of vitamin B12 shots, which must be inserted intramuscularly. In order to keep from getting deficient again, you may need to continue receiving B12 shots for life.
