Folic acid, which is found in oranges and green, leafy vegetables, decreases the risk of neural tube defects and may reduce serum homocysteine levels (which are a coronary artery disease risk factor). It may also have a therapeutic role as an adjuvant therapy for the treatment of methanol toxicity, since it enhances the elimination of formate.

The RDAs for folic acid are as follows [14] :

  • Age 14 years and older - 400 mcg

  • Pregnancy (14-50 y) - 600 mcg

  • Lactation (14-50 y) - 500 mcg
