What is Folic Acid?
Folic acid is the synthetic form of vitamin B9 that is often added to supplements and fortified foods to address deficiencies. As mentioned earlier, folate is the natural form of vitamin B9 found in foods, while folic acid is a synthetic version created in a laboratory. This synthetic form is more stable and can provide consistent levels of vitamin B9, making it a popular choice for supplementation.
One of the main reasons folic acid is used in supplements and fortified foods is to prevent folate deficiency. Folate deficiency can lead to various health problems, especially for pregnant women. Adequate levels of vitamin B9 are crucial during pregnancy for the development of the baby’s neural tube and to reduce the risk of birth defects like spina bifida.
Folic acid is also preferred in certain situations where the body may have difficulty absorbing or utilizing folate from whole foods. It is easier for the body to convert folic acid into the active form of folate that it can use. This makes it a convenient option for individuals who may have higher requirements of vitamin B9 or who struggle to incorporate sufficient folate-rich foods into their diet.
While folic acid can be beneficial in addressing deficiencies, it’s important to be mindful of the potential side effects and risks associated with excessive intake. Taking high doses of folic acid supplements for extended periods can mask vitamin B12 deficiency, which can lead to nerve damage. It’s always advisable to consult with a healthcare provider to determine the appropriate form and dosage of vitamin B9 for individual needs.

| Fortified cereals |
| Enriched bread and pasta |
| Supplements |
| Multivitamins |
Absorption and Utilization
Folate is easily absorbed and utilized by the body, while folic acid needs to be converted to another form before it can be effectively utilized. When folate-rich foods are consumed, such as leafy greens, legumes, and citrus fruits, the natural form of vitamin B9 is readily absorbed in the small intestine. Once absorbed, it is transported to the liver, where it is converted into its active form, known as 5-methyltetrahydrofolate.
On the other hand, folic acid, which is commonly found in supplements and fortified foods, requires an enzymatic process to convert it into a bioavailable form. This conversion takes place in the liver and other tissues, where folic acid is converted into dihydrofolate and then further transformed into 5-methyltetrahydrofolate.
The conversion of folic acid into its active form is not as efficient as the absorption of natural folate. Some individuals may have genetic variations that impair this conversion process, resulting in reduced utilization of folic acid. This is why some healthcare providers recommend using methyl folate, a form of folate that bypasses the conversion process and is readily available for utilization by the body.
| Key Points | |
|---|---|
| Folate | Folic Acid |
| Easily absorbed and utilized | Requires conversion to active form |
| Found in natural food sources | Synthetic form used in supplements and fortified foods |
| Processed in the small intestine | Converted in the liver and other tissues |
Importance of Folate and Folic Acid
Folate and folic acid are essential for a variety of bodily functions. They play a crucial role in cell growth and division, DNA synthesis, and the formation of red blood cells. Adequate levels of folate are particularly important during periods of rapid cell growth, such as pregnancy and infancy.
Folate is known to reduce the risk of certain birth defects, such as neural tube defects, when taken before and during early pregnancy. It also supports brain health, may reduce the risk of heart disease, and is involved in the metabolism of homocysteine, an amino acid associated with cardiovascular health.
Folic acid supplementation has been recommended for pregnant women to ensure sufficient intake, as it is challenging to obtain optimal levels of folate from diet alone. However, it’s important to note that excessive folic acid intake may have adverse effects on health, and unmetabolized folic acid in the bloodstream can be a concern. This is why it’s crucial to consult a healthcare provider to determine individual needs and the proper form and dosage of vitamin B9.
