A recent study finds that women with a low vitamin B12 are more likely to have a preterm birth. The study, published in the American Journal of Epidemiology, also found that low maternal vitamin B12 led to low birth weight in newborns as well. Low birth weight and preterm births are a leading cause of death in infants in the first 28 days of life.
Megan McNamee, Babymoon’s Registered Dietician, recommends natural sources of vitamin B12 such as:
Animal proteins, including meat, fish, pork and poultry, as well as eggs and dairy are great sources. Vegetarian sources include fortified products (like cereals and non-dairy milks) and nutritional yeast.
Most prenatal vitamins, like Thorne Basic Prenatal, will contain above-adequate amounts of B12, so additional supplementation is not necessary if women are regularly taking their prenatal vitamin. Since vitamin B12 is water soluble and is not stored in the body, it is okay for prenatal vitamins to have higher doses than the Recommended Daily Allowance of 2.6mcg for pregnant women.
