Product Overview
Lutein Esters are the core natural carotenoid active ingredients isolated and purified from Tagetes Erecta (Marigold flower). As the most classic eye-health botanical compound and approved natural food colorant (E161b), lutein esters exist in two mature commercial forms: Lutein Esters powder and Lutein Esters oil suspension.
We adopt advanced low-temperature extraction, saponification, purification and refining technology to ensure stable active content, low impurities and excellent batch consistency. The powder series is flexible for various solid formulations, while the oil suspension series is specially customized for softgel and oil-based nutrition products. Both forms retain the natural antioxidant and eye-protecting characteristics of marigold carotenoids.
