Omega-3 EPA+DHA
DHA is structurally essential for the fetal brain and retina — among the most evidence-backed nutrients for neurodevelopment.
Tracked by these blood markers
Trimester focus
| Stage | For the mother | For the baby |
|---|---|---|
| First trimester | Needs are present but lower; the neural tube is still closing, not yet building bulk brain tissue. | Begins incorporating DHA into the earliest neural membranes. |
| Second trimester | Demand rises as the fetal brain begins its major growth phase. | DHA accretion into the brain and retina accelerates. |
| Third trimester | Needs peak — the single biggest DHA-transfer window of pregnancy. | The fetal brain's DHA content multiplies during this trimester alone. |
