What are marigold extracts？
The marigold extract mainly contains lutein and zeaxanthin. Lutein, also known as "phytolutein", coexists with zeaxanthin in nature. Lutein and zeaxanthin are the main components of plant pigments such as corn, vegetables, fruits, and flowers, and are also the main pigments that constitute the macular region of the human eye.
In nature, lutein is found in dark green leafy vegetables such as kale, kale, spinach, and flowers such as calendula and marigold. Human eyes contain high amounts of lutein and zeaxanthin, but these two elements cannot be manufactured by the human body and must be supplemented by foods containing lutein and zeaxanthin. Without these two elements, the eyes will be blind. Extracts obtained from marigold flowers provide a rich source for this medicinal benefit.
What is Lutein?
Lutein, found in some vegetables, fruits, and egg yolks, is a nutrient with many benefits. It is a member of the carotenoid family. Carotenoids are a class of chemicals related to vitamin A. Beta-carotene is well known as a precursor of vitamin A, but there are about 600 other compounds in this family that need to be understood. They have many in addition to lutein, such as alpha-carotene, lycopene, zeaxanthin, and beta-zeaxanthin.
What are the benefits of the marigold extract?
Marigold extract Lutein and other carotenoids are believed to have antioxidant properties. Antioxidants protect cells from damage caused by free radicals, a damaging byproduct of normal metabolism. Free radicals in the body rob other molecules of electrons and damage cells and genes in a process called oxidation.
Research conducted by the Agricultural Research Service of the United States Department of Agriculture (USDA) shows that lutein fights free radicals like vitamin E, a powerful antioxidant. Concentrated in the retina and lens, lutein protects vision by neutralizing free radicals and increasing pigment density. Lutein also has a shading effect against damaging glare.
