Vitamin B, specifically vitamin B9, is a man-made form of folate, which is called folic acid. Folate can also be called as folacin and/or vitamin B9. The main purpose of this type of vitamin is to help in the production of DNA as well as RNA (these are the body's genetic material). This is specially important when the cells and/or tissues in the human body are growing rapidly, specifically during the time of infancy, adolescence and pregnancy. When helping during pregnancy, vitamin B9 helps in preventing birth defects. Folic acid also works along with vitamin B12 to help in the making of red blood cells. Another function is for B9 and B12 is to help the iron content in our body function properly.
