Folic acid, also known as folate, is a type of B vitamin that plays a critical role in various bodily functions. It is a water-soluble vitamin that is vital for forming healthy cells, particularly red blood cells. Folic acid is measured in micrograms per liter (µg/L) when assessed through blood tests. This measurement helps doctors and health professionals determine if an individual has appropriate levels of folate in the body, which is essential for maintaining good health and preventing certain conditions.
If you are undergoing a blood test for folic acid levels, understanding its role and why it matters is important for interpreting the results.
Folate plays an essential role in several of our body’s networks. Primarily, it is crucial for DNA synthesis and repair, which is vital for cell division and growth. Because of its role in the creation of nucleic acids, folic acid is particularly important during periods of rapid growth such as pregnancy and fetal development. It is also responsible for converting the amino acid homocysteine into methionine, an essential function as elevated homocysteine levels are associated with cardiovascular diseases.
Besides, folate aids in the production of red blood cells, thereby preventing anemia which can lead to tiredness and weakness.
When your folic acid levels fall outside the normal range, it can lead to various health issues. A deficiency in folate may cause megaloblastic anemia, where the body produces improperly functioning red blood cells leading to fatigue, weakness, and shortness of breath. In pregnant women, low folate levels increase the risk of birth defects such as spina bifida and anencephaly.
Excessive levels of folic acid, although rare, can hide vitamin B12 deficiency symptoms, potentially allowing nerve damage to progress undetected. Balancing folate levels is crucial for reducing these risks.
The optimum folic acid levels in the blood are generally between 5 to 20 µg/L for adults. Pregnant women may have different reference ranges, and it’s important to consult with a healthcare provider for specific values tailored to individual health needs.
To improve or maintain your folate levels, include folate-rich foods in your diet. These include leafy greens like spinach and kale, citrus fruits, beans, peas, and fortified grains. Supplements are another option, especially for those with increased demands such as pregnant women or individuals with certain health conditions.
