Comment by VitaminDWiki
Omega-3 and Vitamin D independantly have been found to reduce pre-term births by about half
Omega-3 and Vitamin D have often been found to be synergistic
Suspect that getting the Omega-3 index > 6 and Vitamin D >40 ng could result in a 4X reduction in preterm births

Ensure a healthy pregnancy and baby - take Vitamin D before conception has the following

Start Vitamin D soon if pregnant VDW 9923

Does not include additional savings to mother
   such as reduction in preeclampsia, miscarriage, gestational diabetes, depression
   nor does it assign any costs for anguish of possible premie death, stillbirth, time off from work, job productivity

Several meta analyses have concluded n-3 fatty acids, including docosahexaenoic acid (DHA), reduce early preterm birth (EPB, < 34 weeks), however, the amount of DHA required is unclear. We hypothesized that 1000 mg DHA per day would be superior to 200 mg, the amount in most prenatal supplements.

This randomised, multicentre, double-blind, adaptive-design, superiority trial was conducted in three USA medical centres. Women with singleton pregnancies and 12 to 20 weeks gestation were eligible. randomization was generated in SAS® by site in blocks of 4. The planned adaptive design periodically generated allocation ratios favoring the better performing dose. Managing study personnel were blind to treatment until 30 days after the last birth. The primary outcome was EPB by dose and by enrolment DHA status (low/high). Bayesian posterior probabilities (pp) were determined for planned efficacy and safety outcomes using intention-to-treat. The study is registered with ClinicalTrials.gov (NCT02626299) and closed to enrolment.

Eleven hundred participants (1000 mg, n = 576; 200 mg, n = 524) were enrolled between June 8, 2016 and March 13, 2020 with the last birth September 5, 2020. 1032 (n = 540 and n = 492) were included in the primary analyses. The higher dose had a lower EPB rate [1.7% (9/540) vs 2.4% (12/492), pp=0.81] especially if participants had low DHA status at enrolment [2.0% (5/249) vs 4.1%, (9/219), pp=0.93]. Participants with high enrolment DHA status did not realize a dose effect [1000 mg: 1.4% (4/289); 200 mg: 1.1% (3/271), pp = 0.57]. The higher dose was associated with fewer serious adverse events (maternal: chorioamnionitis, premature rupture of membranes and pyelonephritis; neonatal: feeding, genitourinary and neurologic problems, all pp>0.90).

Clinicians could consider prescribing 1000 mg DHA daily during pregnancy to reduce EPB in women with low DHA status if they are able to screen for DHA.

Reviewer comment: “The authors noted negative pregnancy outcomes (such as gestational diabetes, preeclampsia, Cesarean delivery, or others), maternal and infant health status (including DHA levels), and serious adverse events post-delivery (such as birth defects, death, or others)”
