Folic acid supplements are best known for supporting a healthy pregnancy as folic acid is essential for fetal nervous system development. It is suggested that pregnant women take 400 mcg of folic acid daily to keep themselves and their growing baby healthy. Folic acid is also important for many other functions in the body such as DNA synthesis and cellular health. As a water-soluble vitamin, folic acid should be consumed daily. While usually found in multi-vitamins and B-complexes, folic acid can be taken by itself. You can also get this essential vitamin as a combination formula such as Folic Acid & B-12 to promote a variety of additional health benefits.
