Physical description & handling notes

• Dark, yellowish brown liquid
• Solid
• Insoluble
• Xanthophyll
• Foods
• Lutein was found to be present in a concentrated area of the macula, a small area of the retina responsible for central vision. The hypothesis for the natural concentration is that lutein helps protect from oxidative stress and high-energy light. Several studies show that an increase in macula pigmentation decreases the risk for eye diseases such as Age-related Macular Degeneration (AMD).

• Xanthophylls are taken for nutritional supplementation, and also for treating dietary shortage or imbalance.
• Take with foods containing vitamin C. Taking lutein with vitamin C may increase the rate of absorption of lutein. Taking lutein with carotenoids or naringenin may reduce lutein absorption.
• Xanthophylls have antioxidant activity and react with active oxygen species, producing biologically active degradation products. They also can inhibit peroxidation of membrane phospholipids and reduce lipofuscin formation, both of which contribute to their antioxidant properties. Lutein is naturally present in the macula of the human retina. It filters out potentially phototoxic blue light and near-ultraviolet radiation from the macula. The protective effect is due in part, to the reactive oxygen species quenching
