Micronutrients & recovery
Routine supplementation with omega-3 LC-PUFA (specifically DHA) during pregnancy reduces the risk of early preterm birth (<34 weeks) and low birth weight.
If you don't eat fish at least twice a week (including oily fish like salmon or mackerel), take a daily supplement providing at least 200 mg of DHA. This reduces the risk of early preterm birth and low birth weight. Avoid large predator fish like tuna and swordfish due to toxin risks.
StrongSupportsHIGH confidence
Regular consumption of fish as well as supplementation of omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) was found to reduce the risk of early preterm birth prior to 34 weeks of gestation... Low birthweight was reduced (RR 0.90, 95% CI 0.82 to 0.99).
