Because your body can't make folate, you need to get it from your diet.
Some foods naturally contain folate. Folic acid is added to other foods. You can also get folic acid from dietary supplements.

We recommend you to supplement better folate/folic acid:
Magnafolate® L Methylfolate(active folate)—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.
