For folate, the DV is 400 micrograms (mcg) of dietary folate equivalents (DFE). However, individuals who are pregnant should consume 600 mcg DFE daily, and individuals who are breastfeeding should consume 500 mcg DFE daily.

We recommend you to supplement better folate:
Magnafolate® L Methylfolate—maximizes the supplementation delivering a "finished" folate the body can immediately use without any kind of metabolization.
It can better supplement the folate that the body lacks.
And you don't have to worry about the accumulation of folate metabolism due to excessive intake.
