What Are the Benefits of Folic Acid?

Folic acid plays a vital role in the development and maintenance of the human body. It is essential for the creation of DNA and other genetic materials and is crucial in the production of red blood cells. Beyond its basic functions, folic acid offers a range of additional health benefits, including:

1. Kidney Disease Management

Folic acid supplementation helps lower levels of homocysteine, an amino acid that tends to rise in people with kidney disease. Elevated homocysteine levels are linked to a higher risk of heart disease and stroke, making folic acid especially beneficial for those managing chronic kidney conditions.

2. Age-Related Vision Loss

Studies show that combining folic acid with vitamins B6 and B12 may help reduce the risk of age-related macular degeneration, a leading cause of vision loss in older adults.

3. Depression Relief

Some research indicates that folic acid, when taken alongside antidepressants, may enhance their effectiveness and help reduce the symptoms of depression.

4. High Blood Pressure

Daily intake of folic acid for about six weeks has been shown to reduce blood pressure, particularly in individuals with hypertension. However, it has not been proven that combining folic acid with blood pressure medications provides additional benefits beyond the medications alone.

5. Folic Acid During Pregnancy

Taking prenatal vitamins with the recommended amount of folic acid is crucial for preventing neural tube defects in a baby’s brain and spinal cord. These birth defects typically develop within the first 3–4 weeks of pregnancy. Research shows that women who take folic acid a year before conceiving can reduce the risk of premature birth by up to 50%.

The Centers for Disease Control and Prevention (CDC) recommend that women begin taking folic acid at least one month before conception and continue daily intake throughout pregnancy.
