Vitamin B9

Vitamin B9, known as Folate or Folic Acid, is crucial for DNA production and cell growth. It's found in leafy greens, legumes, and fortified foods and is particularly important during pregnancy to prevent neural tube defects. The recommended intake is 400 mcg for adults, with higher amounts for pregnant women. Deficiency can lead to congenital disabilities and anemia, while excess intake, especially from supplements, can mask B12 deficiency symptoms.
