Active Components and Constitutional Formula
Lutein from Tagetes erecta L. is a purified extract obtained from marigold oleoresin, which is extracted from the petals of marigold flowers with organic solvents. The final product, after saponification, contains, as a major component, lutein and a smaller proportion of zeaxanthin. Lutein (3R,3’R,6’R-βε-carotene-3,3’-diol) is a member of a group of pigments known as xanthophylls and has no provitamin A activity.

Indications and Usage
Lutein is a natural part of human diet when fruits and vegetables are consumed. For individuals lacking sufficient lutein intake, lutein-fortified foods are available, or in the case of elderly people with a poorly absorbing digestive system, a sublingual spray is available. As early as 1996, lutein has been incorporated into dietary supplements. While no recommended daily allowance currently exists for lutein as for other nutrients, positive effects have been seen at dietary intake levels of 6–10 mg/day. Lutein, a potent antioxidant, is used to prevent severe visual loss in patients with early age-related macular degeneration (AMD), but its effect on I/R insult is unclear.
It is also used as a food colouring agent and nutrient supplement (food additive) in a wide range of baked goods and baking mixes, beverages and beverage bases, breakfast cereals, chewing gum, dairy product analogs, egg products, fats and oils, frozen dairy desserts and mixes, gravies and sauces, soft and hard candy, infant and toddler foods, milk products, processed fruits and fruit juices, soups and soup mixes in levels ranging from 2 to 330 mg/kg.
