Lutein and Zeaxanthin

Lutein and Zeaxanthin

Lutein and zeaxanthin are naturally occurring dark-yellow carotenoid pigments abundant in plants such as yellow (e.g., corn pumpkins) and dark-green leafy vegetables (e.g., spinach).

Forms

• Lutein and zeaxanthin Ester: In nature, lutein and zeaxanthin occur freely (not bound) or in the ester form (bound to fatty acids). The commercial lutein ester extract is prepared from marigold flowers (Tagetes erecta), which are dried, milled, and extracted. The resulting xanthophyll-ester mixture is then purified, concentrated, standardized for lutein and zeaxanthin content, and suspended in vegetable oil. Lutein and zeaxanthin esters are hydrolyzed to free lutein and zeaxanthin by the body for absorption.

Major Health Benefits
