Reply To: full circle and excess b12

[Ryann Kipping, MPH, RDN, LDN]

Hey, Tessa! I’ve chatted on this before as almost all the prenatal vitamins I recommended have close to this amount of B12. The RDA for most nutrients (what is used to get the % daily value) is based on research done in men, not women nor pregnant women. Needless to say, for most nutrients research in pregnant women lends different necessary amounts of certain nutrients. One nutrient that is super far off is B12 which is why all these prenatal vitamins have what seems like a crazy high percentage more than what is shown as “necessary”. I hope this makes sense!
