Lutein: What It Is, What It Brings and How to Choose a Supplement
Also known as Lutein and zeaxanthin, macular carotenoids
Lutein is the yellow carotenoid the eye concentrates in the macula. It is one of the clearest examples of a supplement ingredient with a defined biological role, which is why it is the cornerstone of modern eye-wellbeing formulas.
What is lutein?
Lutein and its partner zeaxanthin are dietary carotenoids found in dark leafy greens, egg yolk, maize and marigold flowers. The retina actively accumulates them in the macula.
Commercial lutein is usually extracted from marigold (Tagetes erecta) and supplied as free lutein or lutein esters.
Traditional and regional use
Dark leafy greens such as sukuma wiki, amaranth and cowpea leaves are staple African vegetables and natural dietary sources. Isolated lutein supplements are a modern development.
What is lutein known for?
Good to know. Supplements containing lutein are food supplements, so their labels describe support for everyday wellbeing.
The large AREDS2 trial studied lutein and zeaxanthin as part of a defined nutrient combination for older adults’ eye health, and it shaped the eye formulas sold today.
Because the retina actively gathers lutein, a steady daily intake from leafy greens and a well-formulated supplement go hand in hand.
How is it used in supplements?
Lutein appears in eye health formulas, usually with zeaxanthin, zinc, vitamin C, vitamin E and sometimes bilberry or astaxanthin.

How to choose a supplement containing lutein
- Check the lutein and zeaxanthin amounts separately in milligrams.
- Compare the formula with the published AREDS2 composition if that is why you are buying it.
- Take with a meal containing fat, since carotenoids are fat-soluble.

Frequently asked questions
Why is lutein in eye formulas?
The eye concentrates lutein in the macula, the part of the retina used for sharp central vision. Eye formulas combine it with zeaxanthin, zinc and vitamins C and E, following the combination studied in AREDS2.
Can I get enough from food?
Dark leafy greens are a good source, and a diet rich in them supplies meaningful amounts. A supplement adds a steady, measured daily amount on top.
