ZeaLutein® Granules is a brick red colour proprietary composition of 1% Zeaxanthin and 5% Lutein, blended in a ratio optimized to provide maximum benefits in eye health, and is available in granulated powder form. The three ingredients are naturally sourced from Tagetes erecta, Lycium barbarum and Piper nigrum, respectively. This blend delivers a perfect ratio of Zeaxanthin and Lutein (1:5) as occurring in the human eye, and is a highly bioavailable form of both these carotenoids due to the presence of piperine to help support vision health, while offering protection from free radicals.
The macula of the eye is yellow in colour owing to the presence of a pigment that is composed of two dietary xanthophyll carotenoids, Zeaxanthin and Lutein.
Lutein and Zeaxanthin pigments protect the photo-receptor cells of the retina from photo-damage, by absorbing blue light. Additionally, Lutein and Zeaxanthin are antioxidants which prevent free-radical damage to the macula.
The role of nutrition, including carotenoid intake, is receiving increasing attention for its potential in providing eye health. A recent research at the University of Utah Medical School, Utah, US, reveals that the protective effect of the combination of Lutein and Zeaxanthin is more potent than the carotenoids individually (Li et al., 2010).
Several studies have described the beneficial effects of dietary carotenoids in providing wholesome nutrition to the eye and promoting macular health. The current recommendation is consumption of foods rich in dietary carotenoids to help support eye health.
