Folic Acid.
Key benefits.
Folic acid reduces the risk of neural tube defects, such as spina bifida, while supporting DNA formation and cell replication as well as helping red cell formation and nerve function.
Folic acid is the man-made form of folate, which is B vitamin (B9) and also known as folacin. If you are pregnant or are trying to conceive, it is recommended that you take a 400ug supplement per day up until you are at least 12 weeks pregnant to avoid serious forms of birth defects.
