Dr said folic acid is a little low what does that mean whats the reason for it?

Folic acid , also known as folate, is vitamin B9. It is needed to make DNA and RNA and a deficiency can result in anemia. It is found in multivitamins and it is also available as a supplement that your doctor can prescribe if your level is low enough. It is found in many foods, including beans, leafy green vegetables, eggs, etc. Eating a well-balanced diet will usually increase your level.
