B12 deficiency causes pre-term birth (higher risk of disease, death) and lower birth weight (yeah, like smoking).
Really at this point it’s a controlled late abortion than a birth, isn’t it?
Globally, preterm birth and low birth weight (LBW) cause more than a third of the 2.9 million neonatal deaths each year, and prevention of these events is an important component of reducing the mortality rate among children younger than 5 years of age (1, 2). The causes of preterm birth, however, are complex, and few interventions have been successful in preventing it (3).
Eat some fucking cheese. So complex.
tfw Mother Nature hates you.
However, in a recent meta-analysis, Haider and Bhutta (10) concluded that multiple-micronutrient supplementation may reduce the risk of LBW and the number of stillbirths but not the risk of preterm birth or neonatal mortality. Thus, a more targeted micronutrient supplementation practice may be warranted.
You can’t supplement stupidity.
If they’d rather the baby die than get over themselves, they don’t deserve kids.
I love the ineffectual response of “supplements won’t work, but our solution is more of them”.
Your intellectual betters, behold!
Importantly, B12 deficiency may be a proxy for inadequate nutritional status, and it is possible that some of our findings are related to nutritional status and not specifically to B12. A predominantly plant-based diet is low in B12 but also other nutrients, such as vitamin D and zinc, that to some degree may be associated with preterm birth (42–44). We did not have information on dietary intake or blood levels of these nutrients. Nutritional status could explain the present finding of an association between B12 and birth weight in low- and middle-income countries but not high-income countries. However, lower vitamin B12 levels were associated with higher risk of preterm birth irrespective of country income. It seems less likely that nutritional status can fully explain this finding.
Vegetarianism: the Third World baby death diet.
Indian women generally have lower dietary intakes of B12 because of their mainly vegetarian diet, making them susceptible to B12 deficiency (46). Additionally, Indian newborns are among the smallest in the world (45). Our findings suggest that pregnancies already at the greatest risk of resulting in small newborns were the ones that were most vulnerable to low levels of B12. The association between B12 and the risk of preterm birth was consistent across studies in both high-income and low- and middle-income countries, and generalization to countries not studied may be feasible.
Stop eating vegan junk food.
In line with our findings, maternal obesity has been associated with B12 deficiency in several populations (47, 48). It has been hypothesized that this association is due to altered fat distribution and metabolism in overweight women compared with normal-weight women (47). Maternal weight is positively correlated with newborn weight (49), and failure to adjust for maternal weight may underestimate a positive association between B12 and birth weight.
Clearly Mother Nature is fatphobic.

Put down the leafy greens.
“However, it appears that when vitamin D and calcium are combined, the risk of preterm birth is increased.”
