Lutein is a yellow carotenoid pigment produced in microalgae, macroalgae and higher plants. In nature, lutein is present as free lutein or lutein esters which are equally bioavailable. In higher plants, lutein plays a role in photo harvesting as well as photoprotection of photosystem II. Marigold flower contains a high concentration of lutein and lutein esters and is used for commercial-level production of lutein.

Free lutein is abundantly present in some microalgal species namely Chlorella pyrenoidosa and Scenedesmus obliquus, which makes them the potential sources for the industrial level-production of lutein.

Lutein shows remarkable antioxidant and anti-inflammatory activities. Several studies showed that dietary supplementation of lutein has health benefits when it comes to oxidative stress-mediated health conditions. Lutein as a functional food provides various health benefits, including protection from age-related health conditions such as macular degeneration, cognitive decline and cardiovascular diseases. Hence, lutein containing nutritional supplements has a high consumer demand.

Lutein extracted from the marigold flower is an authorized food colourant for flavoured milk drinks.
