Effect of lutein supplementation on blood carotenoids and vitamins in a variety of marine mammals
Lutein, an oxygenated carotenoid concentrated in the retina in a variety of species, may enhance ocular health (Mares-Perlman et al., 2002). Given the high incidence of ocular pathology in captive marine mammals (Dunn et al., 1996), it was hypothesized that a lutein supplement may protect against some of these conditions. This trial examined the response of different marine mammals to...
