Yes. In addition to a healthy diet rich in folate, you should also take folate supplements. These can be purchased from health food stores and pharmacies.
High folate intake can help prevent up to 70% of birth defects. It is important to remember that folate does not prevent all birth defects.

We recommend you to supplement better folate:
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.
