PRENATALOne A Day

Women's Prenatal 1

Covers prenatal basics but uses folic acid instead of methylfolate. Up to 40% of women carry MTHFR gene variants that limit folic acid conversion. For neural tube defect prevention, that's not an acceptable gamble. Ritual or Thorne prenatals use the active form.

6.5/10
GOOD

Covers the prenatal basics but with notable gaps. Iron at 28mg (ferrous fumarate) is well-dosed for pregnancy. DHA at 200mg hits the minimum effective dose. However, folic acid instead of methylfolate is a concern since up to 40% of women have MTHFR variants affecting conversion. Vitamin D3 at 400 IU is well below the 1000 IU minimum. B12 at 5.2mcg is far below therapeutic range. Calcium at 150mg is token.

What We Like

  • DHA at 200mg supports fetal brain development.
  • Iron at 28mg is appropriate for pregnancy needs.
  • Widely available and affordable.

Watch Out For

  • Uses folic acid, not methylfolate. 40% of women have MTHFR variants.
  • Cyanocobalamin instead of methylcobalamin.
  • Calcium at 150mg is insufficient (need 1000mg during pregnancy).
  • Vitamin D at 400 IU is below modern recommendations.
