Importance of Choline and DHA in Infant Development
Key Nutrients for Brain and Eye Development
Recent research underscores the significance of choline and docosahexaenoic acid (DHA) in supporting brain and eye development in infants, as highlighted in a review paper on maternal and infant nutrition.
Current Dietary Intake Trends
National survey data reveal that a significant number of adult Americans do not meet the recommended dietary intake of choline and DHA. Both nutrients are crucial for various physiological processes and are integral components of cell membranes. The average adult requires between 425 to 550 mg of choline daily, alongside a total of 250 mg of eicosapentaenoic acid (EPA) and DHA. However, these requirements are heightened in vulnerable groups, particularly pregnant and lactating women, due to increased nutritional demands for fetal development.
Recommendations from Health Organizations
Leading health organizations, including the American Academy of Pediatrics (AAP), the European Food Safety Authority (EFSA), and the World Health Organization (WHO), recognize choline and DHA as essential nutrients during pregnancy.
Research Findings on Choline and DHA
Impact on Infant Development
Choline and DHA play a vital role in infant brain and eye development, predominantly due to their concentrations in nerve and retinal tissue. A recent review published by Pharmavite LLC, the manufacturer of Nature Made vitamins and supplements, explores the latest research surrounding these nutrients within the context of maternal and infant nutrition.
Long-term Implications of Nutrient Deficiency
The study, presented in the journal Nutrients, indicates that deficiencies in choline and DHA during early life could have lasting effects on brain development, cognitive performance, and visual capabilities in infants. Furthermore, the findings suggest that these nutrients may provide enhanced benefits when consumed together, advocating for co-supplementation strategies during both prenatal and postnatal care. The combination of choline and DHA is observed to offer greater advantages for both mothers and infants compared to each nutrient taken alone.

Recommendations for Prenatal Care
Susan Hazels Mitmesser, PhD, vice president of science and technology at Pharmavite, emphasizes the importance of understanding maternal nutrient requirements. She notes, “Prenatal care can be improved with a greater understanding of maternal nutrient needs and how an individual’s dietary intake, as well as their genetic and lifestyle factors, may impact metabolism of these important nutrients…as part of prenatal care, it may be beneficial to include testing of key nutrients such as DHA and choline, to ensure adequate intake levels are being met.”
