Folic acid, also called vitamin B-9 or folate, is a critical nutrient for pregnant women, as it is needed for the healthy development of the spine in the fetus. However, like other B vitamins, folic acid also helps the body metabolize food to produce energy. Folic acid assists in nerve and heart functioning, metabolizes proteins and fats and aids in keeping your eyes, skin and hair healthy. Folic acid also treats vitamin deficiencies and related disorders. Consult your doctor before taking folic acid or other supplements.
Sources
Folic acid and other B vitamins are water-soluble and cannot be stored in the body. You must acquire this vitamin from your daily nutrition. The University of Maryland Medical Center notes that rich food sources of folic acid include beans, peas, lentils, whole-wheat products, beets, broccoli, Brussels sprouts, spinach, oranges and liver.
Function
As a drug, folic acid is used to treat folic acid deficiency and some types of anemia in which there are low levels of red blood cells or erythrocytes. The National Institutes of Health notes that folic acid is also important for producing and maintaining other cells in the body and protecting the DNA genetic matter in your cells. Your doctor may prescribe folic acid in combination with other medications.
Folic Acid Drugs
Folic acid medication is available in tablet form and is usually taken once a day. Drugs.com advises that though folic acid is considered a vitamin, it is still a potent drug and should only be taken exactly as prescribed. Do not take more or less of this drug or stop taking it without consulting your doctor. If you have been prescribed folic acid to treat a deficiency, you will likely experience improvement in your symptoms in as early as 24 hours. However, do not stop the recommended dosage even if you feel better.
Diseases
The University of Maryland Medical Center states that folic acid works with vitamins B-6 and B-12 as well as other nutrients to balance levels of the amino acid homocysteine in the blood. High levels of homecysteine are thought to be associated with chronic conditions, such as heart disease, and may also be linked to Alzheimer's disease and depression. Your doctor may prescribe folic acid to maintain healthy levels of homocysteine and help decrease the risk of illness.
