Lorenzo Perez-Rodriguez et al.
The Journal of experimental biology, 211(Pt 13), 2155-2161 (2008-06-17)
In animals yellow-orange-red sexual traits pigmented by carotenoids have been suggested to act as signals of current health. Because carotenoids have important physiological functions, individuals might trade-off allocating these pigments to self-maintenance versus coloration. Carotenoids may act as scavengers of

A major factor in the direct determination of lutein in spinach extracts proved to be obtaining reproducible and stable chromatography of lutein. This was achieved on a C30 column with the mobile phase acetone-0.1M triethylammonium acetate (TEAA) buffer (pH 7)

Investigative ophthalmology & visual science, 54(6), 4034-4040 (2013-05-09)
While the role of the macular pigment carotenoids in the prevention of age-related macular degeneration has been extensively studied in adults, comparatively little is known about the physiology and function of lutein and zeaxanthin in the developing eye. We therefore

We investigated the effect of daily supplementation with lutein (L) capsules on macular pigment optical density (MPOD) and visual acuity (VA) in patients with early age-related macular degeneration (AMD). A randomized, double-blind, placebo-controlled, two-center investigation of the effects of L

Experimental eye research, 115, 172-177 (2013-07-31)
Supplementation with carotenoids is proposed to protect against age-related macular degeneration. There is, however, considerable variability in retinal macular pigment response, which may be due to underlying genetic variation. The purpose of this study was to determine whether genetic factors
