                  Folate deficiency anaemia has been a common complaint among many women.

What is Folate?

Folate, a B complex vitamin, has gained popularity in recent years for its role in pregnancy and foetal development. Being a water-soluble vitamin, folate requires daily replenishment in the body. You may have heard the term 'folic acid' used interchangeably with folate. Folic acid may be distinguished from folate as being the synthetic version of the biologically active form-folate. The term folate originates in the Latin word 'folium', which means leaves, owing to its adequate availability in leafy vegetables.

Normal Folate Levels

Folate deficiency or excess is determined based on blood tests that measure your serum, plasma, and red blood cells' folate count. Doctors also recommend doing a Complete Blood count, vitamin B 12 blood levels along with your serum folate blood test. You may consider taking a Welzo folate blood test to help diagnose folate deficiency. Evaluating your serum iron levels may also be advised.

Serum Folate

The normal levels of folate, as tested in the serum, are as below:

Normal serum folate levels (Adults): 4.5-45.3 nmol/L

Although less than 7 nmol/L is considered borderline folate deficiency and may be indicative of underlying anaemia.

Low Folate Levels

Low levels of serum folate are often indicative of anaemia. It may also be caused by underlying chronic diseases like malabsorption or irritable bowel disease. Poor folate intake and prolonged folate deficiency have been associated with cardiovascular and neurological diseases and cancer. Insufficient folate levels in pregnant mothers carry the risk of neural tube defects in the foetus affecting the brain and spinal cord development.

Role of Folate in the Body

Red cell folate has been used as a marker in the diagnosis of an underlying disease like celiac disease, inflammatory bowel disease or megaloblastic anemia.

Folates are a major source of fuel and energy for the smooth function of various organ systems in the body. It has long since been known for its role in brain development and foetal growth. During pregnancy, folate plays a key role in a foetus's genetic makeup, development, and growth and continues to be essential through adolescence and puberty. Its role in DNA synthesis and healthy red blood cells cannot be missed. It is necessary for the absorption of iron and, thereby, maintaining iron and haemoglobin levels in the body. Its protective function in cardiovascular and nervous health has made dietary intake of folate a priority. Research has shown folate to have anti-cancer properties making it useful in cancer prevention.

Recommended Dietary Intake of Folate

A daily intake of 200µg of folic acid is recommended for all adults.

Dietary Sources

Folate can be obtained in adequate amounts from the food we need daily, but it requires a bit of conscious eating to make the most of our dietary intake and maintain optimum folate levels in our bodies.

Some of the sources of folate may include:

  • Leafy vegetables like spinach and kale

  • Vegetables like brussels sprouts, asparagus,

  • Fruits like grapes, melons, oranges, and strawberries

  • Legumes like kidney beans, soybeans, peas, chickpeas

  • Nuts like almonds and peanuts

  • Seeds like sunflower seeds

  • Meat sources include meat, kidneys and liver

  • Eggs

  • Whole grains like brown rice

In some places, we may get folate in the form of fortified foods like fortified cereals or pasta

Management of Folate Deficiency

Green leafy vegetables and citrus fruits rich in folic acid should be consumed in adequate amounts to reduce folate deficiency.

Insufficient folate levels require proper investigation and diagnosis of underlying anaemia or other health disorders requiring treatment.

Folic Acid Supplements

Your doctor may prescribe folic acid supplements for maintaining adequate folate levels in your body. You may consider taking the Welzo Active Iron and B Complex plus Women's supplements that include folic acid along with iron and other B complex vitamins that would benefit your health and reduce any underlying vitamin deficiency.
