Smart Facts Folic acid is an essential B vitamin that supports the heart.* Folic acid also plays a significant role in the formation of new cells and is an important vitamin for women.* This supplement also contains B-6 and B-12 that, along with Folic Acid, help to maintain homocysteine levels that are already within the normal range.* Women who consume healthful diets with adequate folate may reduce their risk of having a child with birth defects of the brain or spinal cord. Folate intake should not exceed 250% of the DV (1,000 mcg).
