Known as "eye protection gold," this extract comes from Hebei’s marigold plantations—where large-scale cultivation ensures high lutein content (≥90%). It filters blue light and supports retinal health, making it a staple in dietary supplements (eye care) and food (natural coloring, infant formula). 

Global demand exceeds $1.5 billion, with China accounting for 70% of production. As digital eye strain and juvenile myopia become global crises, its demand will surge exponentially.
