Description
Lutein is extracted from marigold flower, and belongs to the “carotenoid” family of substances. Medical experiments have proved that the natural lutein contained in plants is an excellent antioxidant.
Adding a certain amount of lutein to food can prevent cell aging and organ aging, as well as prevent vision loss and blindness caused by age-related macular degeneration.
Through a series of medical studies, carotenoids have been suggested. It is used as a cancer preventive agent, a life prolonging agent, an ulcer resistance agent, a heart attack and coronary artery disease resistance agent.
At the same time, lutein can also be used as a feed additive for the coloring of poultry meat and eggs, and has also been used as a coloring and nutritional health care agent in the food industry.
