Lutein: Nature’s Yellow Shield for Plants and Vision
Lutein is a plant-based carotenoid, often considered a vitamin, closely related to beta-carotene and vitamin A. Derived from the Latin word luteus (yellow), it is a xanthophyll found in over 600 natural carotenoids. Synthesized only by plants, lutein is abundant in leafy greens like spinach, kale, and in marigold flowers, which are particularly rich sources. In plants, it helps regulate light energy during photosynthesis by protecting against excess light. In humans, lutein is a powerful antioxidant vital for eye health, accumulating in the macula and lens to help prevent age-related macular degeneration and cataracts. Along with zeaxanthin, it contributes to the vibrant colors in many fruits, vegetables, and flowers. Its molecular formula is C₄₀H₅₆O₂ with a mass of 568.87.

Antioxidant
The synergistic antioxidant activity of two carotenoids, lutein and zeaxanthin, was investigated using a combination of in vitro antioxidant-based and in vivo antioxidant methods based on the in vivo ethanol oxidative damage model in mice. The synergistic antioxidant activity of lutein and zeaxanthin was found to be better when the ratio of lutein to zeaxanthin was 1:2. In the study of the relationship between lutein and brain ω-3 polyunsaturated fatty acid (PUFA) oxidation, it was found that mitochondrial lutein was negatively correlated with docosahexaenoic acid (DHA) oxidation products. The accumulation of subcellular lutein and its relationship with DHA oxidation in the primate brain was also investigated, suggesting that lutein may be related to antioxidant function in the brain.
Lutein: A Powerful Ingredient for Food, Wellness, and Feed
Lutein is a natural pigment used in food, health supplements, and animal feed for color and eye health benefits.
In the Food Field
Lutein provides a bright yellow color and is stable under light, heat, acid, and alkali. Insoluble in water but soluble in oil and ethanol, it is widely used as a natural coloring agent in pastries, beverages, and jellies. It retains over 90% stability even after six months of storage.
For Health Products
Lutein is a carotenoid known for protecting eye health and preventing age-related macular degeneration. Approved by the U.S. FDA in 1995 and by China in 2008, marigold-derived lutein is now widely used in health foods and dietary supplements for its strong antioxidant and vision-supporting properties.
For Feed Product
Feed-grade lutein powder enhances yellow coloration in poultry skin, fat, shins, and egg yolks, and is also used in aquaculture for coloring trout, salmon, shrimp, and crab. In chicken feed, lutein accumulates in egg yolks, improving color and production performance, resulting in vibrant yellow poultry products.

Lutein & Zeaxanthin: Proven Support for Macular Health & AMD Management
Lutein and Zeaxanthin: Clinically Backed Nutrients for AMD and Vision Care
Supplementation with Lutein and Zeaxanthin has been shown in randomized controlled trials to increase macular pigment density, improve visual function, and reduce the risk of progression from intermediate to late-stage AMD, particularly neovascular AMD.
A 6-month course of lutein supplementation in AMD patients led to a 27.9% increase in MPOD and notable improvements in differential light threshold (MDLT), visual acuity (VA), and contrast sensitivity, supporting better visual performance and retinal health.
In a double-blind study, early AMD patients who consumed 10 mg of purified lutein and 0.3 mg of zeaxanthin (with or without antioxidants) showed a 50% increase in MPOD and significant improvement in visual functions like glare recovery, contrast sensitivity, and visual acuity.
An open trial found that long-term lutein supplementation significantly boosted macular pigment density, supporting its use in ongoing eye health maintenance, improvement of visual performance, and prevention of age-related eye diseases such as macular degeneration.
Safe Intake of Lutein Supplements
Lutein is safe at doses up to 20 mg/day, with no toxicity observed even at higher levels.
Increasing doses of lutein supplements significantly increased the serum level of lutein, and doses up to 10 mg were safely administered. No toxicity was Observed15
The observed safe level risk assessment method indicates that the evidence of safety is strong at intakes of lutein up to 20mg/d., although much higher levels have been tested without adverse effects14
