Prenatal Nutrition Belongs Inside Prenatal Care

Deep-research article on prenatal nutrition, built around what the human evidence actually shows and why it belongs inside prenatal care. In the United States in 2023, 669 women died of maternal causes (18.6 per 100,000 live births); the rate for Black women was 50.3 per 100,000 live births, significantly higher than white (14.5), Hispanic (12.4), and Asian (10.7) women (NCHS Health E-Stat 100, 2025). In a Cochrane review of 70 randomized trials involving 19,927 women, omega-3 LCPUFA during pregnancy was followed by fewer preterm births before 37 weeks (11.9% vs. 13.4%; RR 0.89, high-quality evidence) and before 34 weeks (2.7% vs. 4.6%; RR 0.58), with a probable increase in prolonged gestation beyond 42 weeks (Middleton 2018). In one randomized trial (494 enrolled, 350 to delivery), vitamin D3 4,000 IU/day most reliably achieved the trial's sufficiency blood level (RR 1.60 vs. 400 IU), with no adverse event attributed to vitamin D (Hollis 2011). In pregnancy trials, daily iron reduced anemia at term by 70% in relative terms (RR 0.30), with no clear differences in other maternal or infant outcomes (Pena-Rosas 2015). No product is named; maternal topics are clinician-first. Evidence grade: STRONG for omega-3 and preterm birth.
