Vitamin B12 and Folate
Vitamins B12 and folate support many different cellular functions throughout the body. B12 supports nerve function, and folate plays a part in converting carbohydrates into energy as well as producing DNA; both B complex vitamins are also essential for making red blood cells.
Folate is particularly important during pregnancy and plays a role in fetal development. A folate deficiency during pregnancy can increase the risk of neurologic defects to the growing fetus.1
Most individuals get enough folate from foods, especially in the U.S., where all grains and cereal products are fortified with folic acid. However, some people don’t consume enough vitamin B12 to meet their needs, while others can’t absorb enough, no matter how much they take in.2
This test measures both your B12 and folate levels to detect any deficiencies and to diagnose the cause of anemia, if present.
Please note that if you're taking high-dose biotin supplements (vitamin B7,) commonly for skin and nail health, you should wait at least eight hours from the last dose before sample collection.
