Vitamin B9 (Folic Acid) - Importance of folic acid for bodily functions and symptoms of folate deficiency

Folate deficiency is one of the most common vitamin deficiency although only small quantities are required for normal bodily functions. Folic acid also known as vitamin B9, folacin and folate plays an essential role in synthesis of nucleic acids and is vital for synthesis of blood cells preventing anemia as well as for the production and maintenance of new cells, DNA and RNA synthesis. It helps to prevent changes to DNA and thus prevents cancer. Inadequate intake of folic acid during pregnancy has been shown to increase the risk of birth defects and pregnancy loss.

The best sources of folic acid are sprouts, leafy vegetables, soybean, egg yolk, liver, cereals, baked products, yeast, mushrooms and fruits. Unfortunately, it is very sensitive to ultraviolet light and heat. Even prolonged exposure to room temperature can greatly reduce the levels of folate acid in foods. In addition, folic acid requires adequate amounts of vitamin B12 to be able to perform its functions. The recommended daily allowance of folic acid for adults is 400 micrograms, while pregnant women should obtain 600 micrograms of folic acid.

The signs and symptoms of folate acid deficiency include: tiredness, weakness, sore tongue,irritability, confusion, behavior disorders including depression, digestive disorders, sleeping difficulties, anemia, slowed growth rate in infants and children and birth defects (neural tube defect) or pregnancy loss

Folate deficiency is also believed to increase the risk of Alzheimer's disease, cancer, cognitive decline, age-associated hearing decline, high blood sugar, high blood pressure, vascular disease, stroke and some other conditions which can seriously affect the quality of life and even lead to premature death.
