Fertility & Prenatal Care
Omega-3s are not only important when trying to get pregnant but also during pregnancy as they promote healthy development in the foetal brain.
DHA is
one of the most important omega-3s for reproductive health, pregnancy and early
life development. Because it is a major structural fat in the brain, eyes and
nervous system, DHA gives foundation to maternal well-being and the healthy
development of a growing baby. For individuals planning to conceive, expecting,
or breastfeeding, consistent DHA intake can make a meaningful difference.
Optimises chances of conceiving
Healthy
fertility depends on strong, flexible and well-functioning cells. DHA is a key
part of cell membranes, influencing their structure, fluidity and function —
all of which are essential for reproductive health in both men and women.
For Men: Promotes Healthy Sperm
Structure and Function
Sperm
cell membranes are rich in DHA. This fatty acid helps keep them flexible and
resilient,
which is important for:
- Healthy sperm formation
- Strong membrane integrity
- Optimal motility (swimming ability)
- Effective interaction with the egg during
fertilisation
Research
consistently shows that men with subfertility or infertility often have low DHA
levels. Without sufficient DHA, sperm quality, quantity and movement can be
significantly reduced, making adequate intake an important factor when planning
for pregnancy.
For Women: Helps Support a
Healthy Environment for Conception
In
women, DHA reinforces reproductive tissue health by contributing to the
structure and fluidity of cell membranes involved in hormone signalling and
early embryo development.
This
helps create conditions that support:
- Healthy fertilisation
- Early implantation
- A stable environment for pregnancy to progress
Studies
also indicate that diets rich in omega-3s,
particularly DHA,
have been associated with improving egg quality and maintaining reproductive
function into later maternal age.
DHA critical for Baby’s
Development
Once
pregnancy begins, DHA becomes one of the most important nutrients for both
mother and baby. The developing baby needs large amounts of DHA to build the
brain, central nervous system and eyes, along with the neural pathways
responsible for learning, memory, attention and behaviour. It is crucial for
the normal development of these systems. A mother’s DHA intake directly
influences how these systems form, laying the foundation for Brain, Vision and
Neurological function in early life and beyond. Infants born prematurely are
considered at higher risk of incomplete neurological and visual development if
DHA intake is insufficient.
Reducing Risk of Preterm
Delivery and Taking Pregnancy Full Term
The
third trimester is especially critical for DHA, as it’s when it accumulates
rapidly in the baby’s brain and retina. Because the baby relies entirely on the
mother for DHA, consistent intake throughout pregnancy is essential. DHA also
supports the structure and function of cell membranes, including those in the placenta,
helping it efficiently transfer nutrients and oxygen between the mother and
baby. This supports foetal growth and ensures the pregnancy progresses
smoothly.
Adequate
DHA intake has been linked to longer pregnancies and a lower risk of preterm
birth. If DHA levels are too low, it can increase inflammation, which may
trigger early labour. DHA helps regulate this inflammatory response,
supporting a balanced immune system that allows the pregnancy to reach full
term. Additionally, proper DHA intake is associated with healthier birth
weights and improved fetal growth. Babies born to mothers with sufficient DHA
are more likely to be born full term, with fewer complications tied to preterm
birth.
By
ensuring optimal DHA availability, particularly in the third trimester, mothers
help support not only their baby’s brain and eye development but also the
health of the placenta and the ability to carry the pregnancy to term.
Maternal Wellbeing During
Pregnancy
Pregnancy
places high nutritional demands on the mother, so maintaining healthy DHA
levels is important for her brain function, emotional balance and overall
wellbeing. DHA also supports cell structure and fluidity throughout the body,
helping the mother adapt to the physical changes of pregnancy. A balanced inflammatory
response, facilitated by DHA, helps the mother’s body handle the stress and
changes of pregnancy, promoting better health during each trimester.
Breastfeeding and Early
Life
After
birth, the baby’s brain and eyes continue to develop rapidly. Breast milk is
the primary source of DHA for infants and the amount of DHA in the milk
reflects the mother’s intake. Maintaining adequate omega-3 levels during
breastfeeding ensures the baby’s nutritional needs are met during this crucial
time of growth.
Laying the Foundation for
Lifelong Health
The DHA
provided during preconception, pregnancy and early childhood helps support
lifelong cognitive, visual and behavioural outcomes. Omega-3s are required in
higher amounts during the first few years of life, when rapid neurological and
cellular changes are taking place. DHA is considered the most important omega-3
for early growth, with studies linking higher DHA levels in childhood to better
learning, memory and behaviour. In one study of nearly 500 schoolchildren,
higher DHA levels were associated with improved reading, memory and fewer
behavioural issues. From fertility through pregnancy and into childhood, DHA
plays a central role in establishing the foundations for healthy development
and overall quality of life.
