Prenatal DHA by Thorne

If you’re pregnant or breastfeeding and rarely eat fatty fish, prenatal DHA is one of the few supplements with clear payoff. This formula delivers 650 mg DHA plus 200 mg EPA per day, a range consistently used in pregnancy trials. It’s a strong fit if your Omega-3 Index is low, you’re carrying multiples, or you avoid seafood for taste, cost, or dietary reasons. It’s also practical if nausea makes fish unappealing, since softgels avoid odor. If your triglycerides are elevated, this amount helps nutrition but isn’t a high-dose omega-3 for lipid lowering.

DHA (docosahexaenoic acid) is the omega-3 your baby’s brain and eyes stockpile fastest in late pregnancy and early infancy. Supplementing raises DHA in your blood and breast milk within 2–4 weeks, which tracks with the Omega-3 Index test. EPA (eicosapentaenoic acid) tags along to improve DHA uptake and supports mom by tempering the rise in triglycerides that happens in pregnancy. Large trials show the biggest benefits for women who start with lower DHA, including fewer early preterm births. Claims around mood or immunity are mixed, so take omega-3s for fetal and infant development first.

Take two gelcaps with a meal, ideally one that contains some fat to improve omega-3 absorption. If you get fishy burps, take them right before the meal or split the dose morning and evening. Most see blood levels rise within 4–8 weeks; recheck your Omega-3 Index during the second trimester or early postpartum to confirm you’re in a good range. If you already eat fish several times weekly, one gelcap daily can serve as maintenance. For dedicated triglyceride reduction, higher-dose omega-3 products are more appropriate than a prenatal DHA.

Prenatal omega-3 from purified fish oil is low in mercury and generally well tolerated. If you’re on blood thinners like warfarin or a direct oral anticoagulant, talk to your clinician before adding fish oil and before any procedure. With fish or shellfish allergy, confirm the source and consider an algal DHA instead. Mild reflux is the most common side effect; taking with food solves it for most. This is not a replacement for prenatal vitamins, iodine, or choline, which address different needs measured by labs like Ferritin and Vitamin D, 25-Hydroxy.
