In this episode of Vitaminix, the spotlight is on Vitamin B9, also known as folate or folic acid. The show explores its vital role in DNA synthesis, cell division, and the formation of red blood cells. Vitamin B9 is especially important during pregnancy, as it helps prevent neural tube defects in developing babies. The episode highlights food sources rich in B9, such as leafy green vegetables, legumes, and fortified grains, and discusses the effects of deficiency, which can lead to anemia, fatigue, and birth defects. It also touches on the importance of folic acid supplements for pregnant women and the need for balanced intake, as excessive amounts can mask symptoms of B12 deficiency.
