Prenatal Omega-3 DHA

Prenatal omega-3 DHA from low-mercury fish or algae supports fetal brain and eye development—two to three weekly servings or clinician-guided supplements.

Prenatal omega-3 DHA is a long-chain fat from low-mercury fish and algae oils linked to fetal brain and eye development. Two to three servings weekly of salmon, sardines, or trout—or algae DHA if vegetarian—fits many guidelines; avoid high-mercury species like swordfish.

Supplements may help when fish intake is low.

Common questions
