Vitamin B9
Folic acid or vitamin B9 is one of the B complex vitamins and is a water-soluble vitamin. Folic acid is important for DNA synthesis and for the functioning of every cell in the body. It plays a significant role in the production of red blood cells. A deficiency of this acid in the body leads to anemia. It also plays a role in the production of white blood cells, platelets, the metabolism of amino acids and nucleic acids, and contributes to the integrity of the gastrointestinal tract.
Approximately half of the total stored folic acid in the body is found in the liver. A healthy person stores about 5 to 15 mg of folic acid in their body.
It plays an important role in the conversion of amino acids, primarily lowering the level of homocysteine in the blood. Elevated levels of homocysteine in the blood can lead to blood vessel blockage. It plays a very important role in pregnant women, as it is necessary for the development of the spine in the embryo. Development is complete and flawless only in the presence of folic acid. Therefore, folic acid supplementation is recommended for pregnant women. It is an essential vitamin for cell division.
