Folate deficiency means you have a lower-than-normal amount of folic acid, a type of vitamin B, in your blood. Folic acid (vitamin B9) works with vitamin B12 and vitamin C to help the body break down, use, and make new proteins. The vitamin helps form red and white blood cells. It also helps produce DNA, the building block of the human body, which carries genetic information. Folic acid is a water-soluble type of vitamin B. This means it is not stored in the fat tissues of the body. Leftover amounts of the vitamin leave the body through the urine. Because folate is not stored in the body in large amounts, your blood levels will get low after only a few weeks of eating a diet low in folate.
