Quick answer: Research consistently links adequate DHA in infancy to healthy brain structure and visual development, because DHA is a primary building block of neural and retinal tissue. Ensuring sufficient DHA — through breast milk, fortified foods or supplements — is a recognised pillar of early-childhood nutrition.
The human brain grows faster in the first two years than at any other time. DHA, a long-chain omega-3, is one of its essential building materials.
What the evidence shows
- DHA is concentrated in the brain’s grey matter and the retina
- Breast milk naturally contains DHA, varying with maternal diet
- Adequate DHA is associated with healthy visual and cognitive development
Meeting the need
DHA reaches babies through breast milk, fortified formula and, as weaning begins, fortified solid foods. For vegetarian families, plant-based (algal) DHA offers a route that fits their values.
As always, individual nutrition should follow the guidance of a qualified paediatrician.
Frequently asked questions
When is DHA most important for babies?
The first 1,000 days — through pregnancy and the first two years — are the critical window for brain development.
How do babies get DHA?
Through breast milk, fortified formula, and fortified weaning foods as solids are introduced.
