Folic acid (3)

Folic acid deficiencies can pose risks during pregnancy, and excessive levels can pose health risks with genetic mutations. Folic acid deficiency can cause symptoms such as fatigue and headaches.

What is folic acid?

Folic acid, also known as vitamin B11 in the U.S. and Belgium (or B9), plays a crucial role in the body. It is essential for the production of DNA, the formation of red blood cells and the development of a healthy fetus during pregnancy. Adequate folate status is important for everyone, but especially for pregnant women and people with certain health conditions. Folate deficiency can lead to health problems such as megaloblastic anemia and developmental disorders during pregnancy.

Folate tests: Serum and RBC

At, we offer two types of folate tests: the Serum Folate Test and the Folate Intracellular (RBC) Test. The Serum Folate Test measures short-term levels of folate in the blood, which are affected by recent diet and supplementation. This test is especially useful for a quick assessment of current folate status. The Folate Intracellular Test measures folate levels in red blood cells, providing a long-term status of the vitamin in the body. This test is particularly useful for people with MTHFR gene mutations, as it provides a more accurate picture of their long-term folate status. Both tests are crucial for assessing folate status and taking appropriate health measures.

Symptoms of folic acid deficiency

Men and women with folate deficiency may experience a variety of symptoms, including general fatigue, weakness, headaches, pale skin and shortness of breath. Specific symptoms such as an irritated mouth or tongue, diarrhea, and changes in mood may also occur. Folate deficiency can lead to megaloblastic anemia, a condition characterized by abnormally large and immature red blood cells. Early detection and treatment of folate deficiency are essential to prevent serious health problems.

Risks of too much folic acid

Although folate deficiency carries health risks, excess folate can also be problematic, especially in individuals with genetic mutations such as MTHFR. Excess folate can mask the fact that a person is vitamin B12 deficient, which can lead to undetected neurological damage. Therefore, it is important to maintain the proper balance of folate in the body and ensure a balanced intake through diet or supplements.

Importance of folic acid testing

Testing folate levels, both in serum and in red blood cells (RBC), is crucial for accurate diagnosis of folate deficiency or excess. Low RBC folate levels can indicate long-term deficiency, which is useful for assessing overall red blood cell health and can help diagnose conditions such as megaloblastic anemia. Serum folate tests are especially important for pregnant women and others at risk for health problems due to folate deficiency. These tests can also identify vitamin B12 deficiency, which is essential for preventing megaloblastic anemia and other related health problems. At, we offer these tests to provide a thorough assessment of folate status, allowing appropriate health measures to be taken.

Treatment and prevention of folic acid deficiency

Treatment of folate deficiency mainly involves supplementing folic acid through dietary changes and supplementation. Foods rich in folate, such as green leafy vegetables, fruits, legumes and fortified cereals, should be included in the daily diet. Folic acid supplements are particularly recommended for pregnant women and those with proven deficiencies. In addition to treatment, prevention of folate deficiency is crucial, especially for women with a desire to have children, as adequate folate levels before and during early pregnancy are essential for fetal development. Regular folate testing can help monitor the effectiveness of dietary and supplement interventions and ensure that folate levels remain within a healthy range.
