DHA supplementation of infant formula at 0.32% of total fatty acids improves visual acuity. Higher amounts of DHA supplementation were not associated with additional improvement of visual acuity.
DHA is present in high concentrations in the central nervous system (CNS) and accumulates during the third trimester prenatally and the first 2 y postpartum (1–4).
Infants at Dallas who were fed control formula with no DHA had significantly poorer visual acuity than did all groups who received DHA-supplemented formulas
Long-term outcomes of DHA-supplementation of infant formula have documented differences in visual and cognitive function at 18 mo to 4 y of age
