Frequently Asked Questions About Folic Acid Supplements

What is Folic Acid?

Have you eaten any leafy greens recently? How about asparagus? If the answer is yes, then you have consumed some folate (vitamin B9).

As such, folate deficiency may cause many manifestations; these include anemia, neural tube defects (problems with the brain and spinal cord of the fetus), depression, diarrhea, inflammation of the tongue, and many others.

In contrast with the naturally occurring folate, folic acid is the synthetic form that is present in supplements and vitamin B9-fortified foods (cereals, flour, pasta, etc). The terms folate, folic acid, and vitamin B9 refer to very closely related compounds.

Inside the body, vitamin B9 must first be converted to THF – the active form – before it can participate in reactions.

The most important of these reactions include:

  • Making new cells and DNA. This is particularly significant in pregnancy.
  • Eliminating homocysteine. Accumulation of this compound may increase the risk of strokes and heart disease.

Folic acid supplements generally come in the form of tablets of differing dosages. Prenatal multivitamins also contain folic acid.

What Are the Uses & Benefits of Folic Acid?

Folic acid is the synthetic version of folate, an essential vitamin. Folic acid is used to increase levels of folate in the body, which can have a variety of benefits. Some primary folic acid uses include:

  • Pregnancy: Folate is vital for a healthy pregnancy. Experts recommend taking 400 micrograms per day of folic acid both before and during pregnancy. This can help reduce the risk of birth defects, particularly those related to the baby’s spinal cord and brain. Most birth defects occur within the first few months of pregnancy, so it’s important for women who may become pregnant to ensure adequate levels of folate/folic acid intake. Folic acid is always included in prenatal vitamins, although standalone folic acid supplements may also be recommended to mothers-to-be.
  • Folate deficiency: It’s possible to become deficient in folate, which can lead to anemia and other health concerns. Folic acid is effective at eliminating folate deficiencies, which can help reduce the risk of anemia, improve nutrient utilization, and more.
  • Cancer: Low levels of folate in the blood have been linked to some types of cancer, and a diet high in folate has been shown to potentially reduce the risk of developing some cancers including breast, colon, lung and pancreatic cancers. However, the relationship between folate and cancer is complex. Taking too much may result in an increased risk of certain cancers while taking the recommended dosage is thought to reduce the risk. Thus, patients are advised to speak with their doctor to work out an ideal dosage amount and timing in order to optimize folate intake.
  • Heart disease: Folate may be beneficial in addressing heart disease. High-dose folic acid supplements have been shown effective in reducing homocysteine levels and improving vascular function in patients already suffering from coronary artery disease. Since high homocysteine levels in the blood are linked to a hardening of the arteries, it’s thought that folic acid’s homocysteine-reducing effects may be beneficial in addressing heart disease. One study also found that men with higher dietary intakes of folate showed a reduced risk for heart attacks and strokes.
  • Other uses: Folic acid has shown some promise in addressing age-related vision loss, high blood pressure, gum disease, cognitive decline, and vitiligo. These are all considered issues that folate is “possibly effective” for, meaning that research has shown positive potential, but there is no conclusive evidence to support these uses. More research is needed.

Although folic acid and folate are often used interchangeably, there are some differences between the two. Folate is a naturally occurring essential vitamin found in foods, while folic acid is the synthetic version of the vitamin.

Some experts believe that folic acid is not absorbed as easily as folate, which can potentially lead to unhealthy levels of unmetabolized folic acid in the bloodstream. Elevated levels of unmetabolized folic acid have been linked to cancer development, difficulty concentrating, changes in sex hormone levels, and trouble sleeping.

Thus, many believe that increasing natural folate intake from foods should be the focus, although there are still some reasons to take folic acid supplements.

Who Can Benefit from Folic Acid?

  • All women who can get pregnant, including those who are not actively trying to get pregnant. Pregnancy increases the nutritional requirements of many substances, as the mother’s body provides nutrients to the developing fetus. Folate is rapidly used up in making the cells of the baby, which can cause folate deficiency. This may increase the risk for the development of birth defects, particularly neural tube defects. The recommendation that women who are not trying to get pregnant take folate supplements are due to the possibility of unplanned pregnancies, and the fact that neural tube defects occur in the first few weeks of pregnancy, when the mother may still be unaware of the pregnancy.
  • Aging adults. Research has shown a relationship between low blood folate levels and a higher incidence of age-related macular degeneration (vision loss) and hearing loss in the elderly.
  • People who suffer from conditions associated with folate deficiency; may include liver disease, ulcerative colitis, kidney disease, and alcoholism.

How Do I Take Folic Acid?

Folic acid supplements are available in tablet or liquid forms. Folic acid supplement dosage varies depending on your diet, but generally speaking, the recommended dosage is higher for women: All women between the ages of 15 and 45 should take 400 micrograms per day.

Women who have had a previous neural tube defect-affected pregnancy should take 400 micrograms of folic acid per day when not planning a pregnancy, and 4000 micrograms per day starting one month before they start trying to become pregnant.

You may take the tablets with or without food. If you forget a dose, take it as soon as you remember. If the day of the missed dose has passed, do NOT take a double dose on the next day; only take the new dose as scheduled.

Are There Any Side Effects of Folic Acid?

Generally speaking, folic acid causes few if any side effects in most people. Long-term consumption of folic acid in high doses may be associated with diarrhea, headache, confusion, skin reactions, asthma attacks, seizures, and heart disease.

How Do I Pick a Good Folic Acid Product?

The highest quality folic acid supplements are made by reputable companies that adhere to strict guidelines in the manufacturing process. Using only high-quality ingredients enables the product to achieve maximum efficacy and safety.

They are also gluten-free, artificial preservative-free, and non-GMO. Practical considerations include small tablet size, availability in multiple dosages, and/or scored tablets that can be easily split into equal doses.
