Folate/folic acid amounts

How much folate/folic acid is in your prenatal (in DFE)?

Also, has anyone ever gotten your blood folate levels tested during pregnancy? If so, what were your levels?

I’m reading that too much folate in pregnancy can be a bad thing (although you want to make sure you get enough), and I’m wondering if my prenatal has too much. Curious what amount of folate supplement raises blood levels to unhealthy levels.
