Take you to understand the difference between lutein and lutein esters

- Aug 06, 2020-


Lutein is a carotenoid, a photosynthetic pigment, and an antioxidant, which can filter harmful light such as blue light. Animals cannot produce lutein on their own and need to be taken from food.

Lutein esters are dark red-brown fine particles produced from marigold flowers through dehydration and crushing, solvent extraction, alcohol purification and vacuum concentration.

Lutein is the main component of plant pigments such as vegetables, fruits, flowers, etc. It is also the main component of the macular area of the retina of the human eye, which can prevent the physiological structure and function of the eye from changing.

Lutein exists in the form of fatty acid esters in most plants. During the saponification process of lutein esters, the molar ratio of lutein is about 1:2.

Lutein esters can be naturally hydrolyzed into free lutein in the human body and increase the bioavailability by 61.6%.
