Brief Summary
This study is designed to test the hypotheses that (1) the third trimester of pregnancy is a period of maternal systemic and ocular carotenoid depletion; (2) prenatal supplementation with 10 milligrams of lutein and 2 milligrams of zeaxanthin will have significant effects on ocular and systemic biomarkers of maternal and infant carotenoid status relative to a matched, standard-of-care prenatal supplement without added lutein and zeaxanthin; and (3) newborn infants with the highest systemic and ocular carotenoid status will have more mature foveal structure. Mothers will be enrolled in the study during their first trimester, and will take the study carotenoid or control supplements for 6 to 8 months. The final study outcome measurements of mothers and infants will be completed within two weeks of the baby's birth.

Outcome Measures
Primary Outcomes (3)
Change in Maternal Macular Carotenoid Levels From Enrollment to Birth of Infant
measured in units of macular pigment optical volume (MPOV). Details regarding methods and criteria used to assess this outcome measure and interpret the values are in the published protocol available at https://doi.org/10.1186/s13063-021-05244-2
up to 13 weeks gestation to birth
Change in Maternal Serum Carotenoid Levels From Enrollment to Birth of Infant
We are reporting only lutein + zeaxanthin concentrations. Unit of measurement is in nanograms per milliliter (ng/ml). Details regarding methods and criteria used to assess this outcome measure and interpret the values are in the published protocol available at https://doi.org/10.1186/s13063-021-05244-2
up to 13 weeks gestation to birth
Change in Maternal Skin Carotenoid Levels From Enrollment to Birth of Infant
Maternal skin carotenoid levels are measured in Raman units.

Study Arms (2)
Carotenoid group
EXPERIMENTALThe Carotenoid group will receive a commercially available prenatal vitamin/mineral/Docosahexaenoic acid (DHA) softgel plus a softgel containing lutein/zeaxanthin in safflower oil.
Control group
ACTIVE COMPARATORThe Control group will receive the same prenatal vitamin/mineral/Docosahexaenoic acid (DHA) softgel plus a softgel containing only safflower oil.
Interventions
Softgel active ingredients: Lutein 10 mg and Zeaxanthin 2 mg in safflower oil
Placebo ingredients: Safflower oil
Eligibility Criteria
You may qualify if:
- Pregnant women, 18 or older of all races and ethnicities who have an uncomplicated obstetric history and plan to deliver either vaginally or by Caesarian section at the University of Utah for their current pregnancy.
You may not qualify if:
- Women who have regularly taken carotenoid supplements containing more than 0.5 mg of lutein and/or zeaxanthin daily during the six months prior to screening
- Women who have significant eye disease associated with macular pigment abnormalities such as Stargardt disease, albinism, or macular telangiectasia type II (MacTel).
- Women with conditions associated with high-risk pregnancy such as adolescent pregnancy, multifetal pregnancy, current or past history of diabetes, pre-eclampsia, previous premature delivery, drug abuse or other significant medical illness

Limitations and Caveats
A limitation of this study was its lack of participant racial, ethnic and socioeconomic diversity. Also, by design, this first-in-humans, randomized clinical trial was limited to low-risk pregnancies. Due to funding and logistical limitations, we could not follow the mothers and their infants beyond their postpartum visit. This meant we were not able to assess the role of maternal breastmilk as a continued source of lutein an zeaxanthin during the first months of life.
