Toyoda Y, Thomson LR, Langner A, et al. Effect of dietary zeaxanthin on tissue distribution of zeaxanthin and lutein in quail. Investigative Ophthalmology & Visual Science. 2002;43(4):1210-21.

Content: Supplementation study with zeaxanthin in quails. Xanthophyll profiles in quail mimic those in primates. Dietary supplements of zeaxanthin effectively increased zeaxanthin concentrations in serum, retina, liver, and fat. The robust response to zeaxanthin supplementation identifies the quail as an animal model for exploration of factors regulating delivery of dietary carotenoids to the retina.

Content: Supplementation study with zeaxanthin in quails. These studies in quail provided the first experimental evidence that lens carotenoids in adult vertebrates can be manipulated by dietary Z supplements.
