Lutein Biggest Supplier Marigold Flower Extract Lutein Powder Oil 5%-90% HPLC Zeaxanthin

The florets of Tagetes erecta are rich in the orange-yellow carotenoid lutein and are used as a food colour (INS-number E161b) in the European Union for foods such as pasta, vegetable oil, margarine, mayonnaise, salad dressing, baked goods, confectionery, dairy products, ice cream, yogurt, citrus juice and mustard. In the United States, however, the powders and extracts are only approved as colorants in poultry feed.

Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The only difference between them is in the location of the double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two.

Lutein is one of over 600 known naturally occurring carotenoids. Found in green leafy vegetables such as spinach and kale, lutein is employed by organisms as an antioxidant and for blue light absorption. Lutein is present in the plant as fatty-acid ester, with one or two fatty acids bound to the two hydroxyl-groups. Saponification of lutein esters yields lutein in approximately a 2:1 weight-to-weight conversion. Lutein is also found in egg yolks, animal fats and the corpus luteum. Lutein is a lipophilic molecule and is generally insoluble in water. The presence of the long chromophore of conjugated double bonds (polyene chain) provides the distinctive light-absorbing properties. The polyene chain is susceptible to oxidative degradation by light or heat and is chemically unstable in acids.

Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is important in the xanthophyll cycle. It is the pigment that gives paprika (made from bell peppers), corn, saffron, wolfberries, and many other plants their characteristic color. Zeaxanthin is one of the two primary xanthophyll carotenoids contained within the retina of the eye. Within the central macula, zeaxanthin is the dominant component, whereas in the peripheral retina, lutein predominates. 

Action:

1. In nature, lutein and zeaxanthin appear to absorb excess light energy to prevent damage to plants from too much sunlight, especially from high-energy light rays called blue light.

2. Lutein and zeaxanthin appear to have important antioxidant functions in the body. Along with other natural antioxidants, including vitamin C, beta carotene and vitamin E, these xanthophylls guard the body from damaging effects of free radicals, which are unstable molecules that can destroy cells and play a role in many diseases.

3. Lutein is concentrated in the retinas of your eyes and is necessary for good vision. A diet rich in lutein may lower your risk of developing cataracts and macular degeneration.

4. Lutein may also help prevent or slow down atherosclerosis, the thickening of arteries, which is a major risk for cardiovascular disease.

5. Zeaxanthin supplements are typically taken on the supposition of supporting eye health. It is believed that lutein, zeaxanthin and meso-zeaxanthin in the macula block blue light from reaching the underlying structures in the retina, thereby reducing the risk of light-induced oxidative damage that could lead to macular degeneration (AMD).
