We have a problem. When discussing vitamin B9, common parlance is to use “folic acid” and “folate” interchangeably, as if the two are different terms for the same thing. Talk to most OB-GYNs about the type of vitamin B9 in your prenatal, and they’ll say the difference doesn’t matter. Look at the average nutrition label, and it’ll list folic acid rather than folate, even though it’s naturally occurring. They are not the same. The difference is meaningful.
