The first 1,000 days between the onset of a woman’s pregnancy and her child’s second birthday offer a unique window of opportunity for good nutrition. Along with a balanced diet, prenatal supplements are routinely recommended to ensure that a pregnant woman consumes adequate amounts of vitamins and minerals known to be essential for a healthy pregnancy and baby. Yet, some prenatal supplements omit nutrients known to help the baby’s developing eyes.
Science shows that lutein and zeaxanthin are antioxidants and may provide a variety of health benefits for the developing baby, most notably in the eyes and brain.1 During pregnancy, levels of lutein and zeaxanthin in a mother’s blood increase.2 Lutein in the mother’s blood has been found to increase by approximately 33 percent between the first and third trimester of pregnancy.3,4 Studies show that both nutrients continue to play a vital role in the development of the eyes and brains of infants and children after birth.5,6
Foods sources of lutein and zeaxanthin include leafy greens, such as kale and spinach, and eggs. Because most diets worldwide typically fall short on vegetables, intakes of lutein and zeaxanthin average from 1 to 3 mg in total per day,7-11 far less than the recommended 10 mg of lutein and 2 mg of zeaxanthin for adults.12
DHA (docosahexaenoic acid) is one of the main omega-3 fatty acids found in fish such as salmon, and in vegetarian forms in certain types of algae. DHA is necessary for healthy cells and is concentrated in the brain and the retina of the eye.
During pregnancy, DHA supports optimal infant brain and eye development and is particularly important in the third trimester when significant brain growth occurs. Maternal DHA supplementation during pregnancy and nursing enhances the level of DHA available to the fetus and infant and may improve certain developmental outcomes, such as eye-hand coordination, motor skills and attention span.13,14
Pregnant women and new mothers can consume DHA from low-mercury, oily fish such as salmon, herring and sardines. Dietary intake of DHA, however, falls far short of recommendations worldwide, creating a need for supplemental sources. Ideally, prenatal and postnatal supplements include DHA as an ingredient.
Vitamins A and E support healthy vision development in different ways. Vitamin A, found in leafy green and orange vegetables, nourishes the retina and the cornea and helps with the maintenance of normal vision. Vitamin E protects the eyes against damage from oxidation, a process much like rusting, which damages healthy cells. By curbing oxidation, vitamin E therefore contributes to the normal development of vision and overall good health of both mother and baby.
