When we talk about pregnancy nutrition, the conversation almost always starts and ends with folate.
And yes, folate matters. It plays a critical role in neural tube development and early cell division.
But there is another nutrient that plays an enormous role in pregnancy and rarely receives the same attention.
DHA.
What Is DHA?
DHA (docosahexaenoic acid) is a long-chain omega-3 fatty acid.
Structurally, it is one of the primary building blocks of the brain and retina. In fact, DHA is one of the most abundant fatty acids found in the brain’s grey matter.
This makes it particularly important during periods of rapid neurological development, including pregnancy.
Why DHA Matters During Pregnancy
During pregnancy, DHA is actively transported across the placenta to support fetal brain and eye development.
In the third trimester, this process accelerates significantly. DHA accumulation in the fetal brain increases rapidly during this stage of pregnancy.
At the same time, the demand for DHA rises, often at a point when many women’s dietary intake remains relatively low.
Research consistently shows that maternal DHA status influences fetal DHA status. In turn, fetal DHA levels play an important role in early neurodevelopment.
Why Many Women Are Not Meeting DHA Requirements
Despite its importance, many women do not meet recommended DHA intake through diet alone.
Even women who regularly consume fish often do so inconsistently. Others intentionally limit fish intake during pregnancy due to understandable concerns around mercury exposure.
This is where the nuance sits.
We want the benefits of DHA.
But we want to avoid unnecessary heavy metal exposure.
What DHA Supports
DHA is not simply a “nice to have” nutrient. It plays a structural role in development.
During pregnancy, DHA contributes to:
• fetal brain development
• retinal development
• cell membrane integrity
• inflammatory balance
There is also emerging research exploring potential links between maternal DHA status and mood regulation in the postpartum period. This area of research continues to evolve, but it highlights the broader role omega-3 fatty acids may play in maternal wellbeing.
Why DHA Is Often Missing From Prenatal Supplements
Unlike folate, DHA is not routinely included in all prenatal vitamins.
And when it is included, the dose is often relatively modest.
For many women, this means dietary intake and supplementation may still fall short of the increased demand that occurs during pregnancy.
A Thoughtful Approach to DHA Supplementation
This is one of the reasons we formulated NeuroNatal DHA separately.
NeuroNatal DHA uses a microalgae-derived source of DHA, which provides the benefits of omega-3 DHA without relying on fish oil.
Microalgae-derived DHA is naturally mercury-free, vegan and sustainably sourced.
Separating DHA from the prenatal formula also allows women to adjust intake more intentionally depending on their dietary habits and individual needs.
Considering Your DHA Intake
If you are planning pregnancy, currently pregnant, or breastfeeding, it may be worth considering whether your DHA intake is truly meeting the increased demand during this time.
Because early brain and eye development begins early and continues throughout pregnancy.
And these foundational processes rely on adequate nutritional support.
