Vitamin B9 Folic acid

Vitamin B9 Function.

Vitamin B9 is more commonly known as folic acid, the synthetic form that is used in fortified foods and supplements. It can also prevent memory loss, relieve symptoms of depression, and is vital for the growth and development of babies during pregnancy.

B9 works with B12 and B6, as well as other nutrients, to control the levels of homocysteine in the blood. High homocysteine levels are linked to heart disease, though researchers don’t know whether it’s simply a marker indicating the presence of heart disease or the cause of it.

It’s necessary for the healthy immune, nervous, and digestive systems and also for producing energy, red blood cell formation, cell division, and the synthesis of DNA and RNA. It’s necessary for replicating DNA, as well as sustaining the bone marrow’s healthy level of red blood cells.

For pregnant women, it’s vital, especially in early pregnancy, in preventing birth defects relating to the brain and the spine. Pregnant women who do not consume enough give birth to premature babies and deliver babies with low birth weights.

Food Sources
